Book excerpt: Biodiesel use and production has significantly increased in the United States and in other parts of the world in the past decade. This change is driven by energy security and global climate legislation mandating reductions in the use of petroleum-based diesel. Recent air quality research has shown that emission of some pollutants such as CO, particulate matter (PM), SO2, hydrocarbons, and carcinogenic polycyclic aromatic hydrocarbons (PAHs) is greatly reduced with biodiesel. However, studies have also shown that some unregulated emissions, such as gas-phase carbonyls, are increased with biodiesel combustion. Very limited research has been done to investigate the particle-phase carbonyl and quinone emissions from biodiesel combustion. Also, very limited studies have investigated the ozone oxidation of biodiesel exhaust PM. Fatty acid methyl esters (FAMEs) are found in high abundance in biodiesel exhaust PM. The presence of these FAMEs in biodiesel exhaust PM can potentially alter the kinetics of the reactions between ozone and particle-phase PAHs. In this study, an Armfield CM-12 automotive light-duty diesel engine operated on a transient drive cycle was used to generate PM from various waste vegetable oil (WVO) and soybean biodiesel blends (containing 0%, (B00), 10% (B10), 20% (B20), 50% (B50), and 100% (B100) biodiesel by volume). The primary PM emissions were sampled using Teflon-coated fiberfilm filters. Laboratory PAHs, FAMEs, and B20 exhaust PM were exposed to ~0.4 ppm ozone for time periods ranging from 0-24 hours in order to study the effect of FAMEs and biodiesel exhaust PM on the ozonolysis of PAHs. Organic chemical analysis of samples was performed using gas chromatography/mass spectrometry (GC/MS). PAHs, carbonyls, FAMEs, and n-alkanes were quantified in the exhaust PM of petrodiesel, WVO and soybean fuel blends. The emission rates of the total PAHs in B10, B20, B50, and B100 exhaust PM decreased by 0.006-0.071 ng/μg (5-51%) compared to B00, while the emission rates for the FAMEs increased with increasing biodiesel content in the fuel. The emission rates of the total n-alkanes in B10, B20, B50, and B100 exhaust PM decreased by 0.5-21.3 ng/μg (4-86%) compared to B00 exhaust PM. The total emission rates of the aliphatic aldehydes in biodiesel exhaust PM (B10, B20, B50, and B100) increased by 0.019-2.485 ng/μg (36-4800%) compared to petrodiesel. The emission rates of the total aromatic aldehydes, total aromatic ketones, and total quinones all generally decreased with increasing biodiesel content in the fuel. With the exception of benzo[a]pyrene, the pseudo-first order ozone reaction rate constants of all the PAHs decreased by 1.2-8 times in the presence of the FAMEs. Phenanthrene, fluoranthene, and pyrene were the only PAHs detected in the B20 exhaust PM, and their ozone reaction rate constants were about 4 times lower than those obtained when the PAHs alone were exposed to ozone. The findings of this study indicate that there are both positive and negative effects to emissions associated with biodiesel use in light-duty diesel engines operating on transient drive cycle.

This book was released on 2016 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical properties (cloud point, kinematic viscosity, and flash point) of biodiesel blends of commercial biodiesel fuels were measured. Four different biodiesel blends (10, 20, 50, 100 %) based on three feedstocks (tallow oil, soybean, and waste cooking oil) were tested, and the results were compared with ultra-low-sulfur diesel (ULSD). All the tests were conducted according to the American Society for Testing and Materials (ASTM) standard methods. The test results were evaluated statistically. The tested properties showed strong dependence on blends, which means that the percentage of biodiesel in a biodiesel/ULSD mixture is an important factor that determines the biodiesel properties. It was also found that the type of feedstock is a controlling factor in the biodiesel properties. Contents of saturated fatty acids and triglycerides at higher percentages are thought to be the main determinant of the degree of the dependence, and also the cause of undesired variations in the cold flow properties, kinematic viscosity and flash point. These variations may be controlled through modifications in the transesterification process or by using additives, which is necessary for better engine performance with biodiesel blends. Particulate matter (PM) emissions from mobile sources are the major contributors of urban atmospheric particulate matter especially PM2.5. Particulate matter released from diesel engines contains various organic and inorganic compounds. It is necessary to measure the PM size distribution shape, elemental and organic carbon etc., released from vehicles in order to quantify the source contribution and understand the possible health impacts. Previous studies stated PM2.5 and PM10 to be highly toxic and roots for respiratory illnesses such as asthma and chronic bronchitis, lung inflammation and also increases cardiovascular related risk factors. Biodiesel is one of alternative fuels that are being increasingly used to reduce the release of PM emissions from mobile sources. The current literature shows that the release of PM from transit buses decreases by increasing the biodiesel blend percentage with regular diesel. In this study, the experiments were conducted on the Toledo Area Regional Transit Authority (TARTA) buses 701 and 802, which run on B20 soybean biodiesel (20 vol% biodiesel + 80 vol% ultra-low sulfur diesel). PM emissions were collected on quartz filter papers and were further analyzed for PM characterization. A new approach of measuring particulate matter has been developed based on the dynamic light scattering and electric double layer of PM particles using a NICOMP 380 ZLS Zeta potential particle size analyzer and sonication process to suspend the PM into a liquid. Regardless of the bus number, average mean diameter was more for emissions from hot idling than cold. Also, 701 has PM of larger diameter than 802 in both idling modes. Tests results were also analyzed for Elemental Carbon (EC) and Organic Carbon (OC). Elemental carbon was formed from fuel rich engine locations at high combustion temperatures, whereas organic carbon was formed from primary fuel combustion and atmospheric chemical reactions at low vapor pressure. EC concentration has reduced to nearly 10% of TC from 701 to 802 during idle modes, whereas in the same situation OC concentration has increase to 89%. Hot idling has been the main source for EC emissions, and to control EC and PM emissions hot idling must be avoided. From all these finding in this study biodiesel fuel with NOx emission controlling equipment's are better than the conventional diesel fuels and are suitable for the diesel engines. This will help in improving the sustainability of the fuel and also moderate the emissions.

This book was released on 2021-09-10 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research related to ambient particulate matter (PM) remains very relevant today due to the adverse effects that PM have on human health. PM are pollutants with varying chemical compositions and may originate from multiple emission sources, which directly affects their toxicity. To formulate effective control and mitigation strategies, it is necessary to identify PM sources and to estimate their influence on ambient PM concentration, a process that is known as source apportionment (SA). Depending on the geographical location and characteristics of an area, many anthropogenic and natural sources may contribute to PM concentration levels, such as dust resuspension, sea salt, traffic, secondary aerosol formation, industrial emissions, ship emissions, biomass burning, power plant emissions, etc. Different methodological approaches have been used over the years to study the aforementioned topics, but some scientific challenges remain, mainly related to the following subjects: real-time chemical analysis and SA, uncertainty estimation of SA results, and analytical optimization for PM samples. Additionally, there are areas in the world for which the results regarding composition and sources of PM are still scarce. The objective of this collection was to include studies on all aspects of PM chemical characterization and source apportionment regarding the inorganic and/or organic fractions of PM.

Download or read book Analysis of Particulate Matter Emission in Diesel Engine Operated with Waste Cooking Oil Biodiesel written by Nur Fauziah Jaharudin and published by . This book was released on 2015 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diesel engines which is an attractive power unit used widely in many fields are among the main contributors to air pollutions for the large amount of emissions, especially particulate matter (PM) and nitrogen oxides (NOx). PM is one of the major pollutants emitted by diesel engine which have adverse effects on human health. Accordingly, many research have been done to find alternative fuels that are clean and efficient. In this study, waste cooking oil (WCO) biodiesel has been used as an alternative source for diesel engine which produces lower PM than diesel fuel. The emission of PM and gaseous emission (carbon monoxide (CO), carbon dioxide (CO2), nitric oxide (NO) and NOx) has been collected from single cylinder diesel engine fuelled with diesel and WCO biodiesel blends (B5, B10 B20 and B100) at five different engine speed (1200 rpm, 1500 rpm, 1800 rpm, 2100 rpm and 2400 rpm) with constant load of 20 Nm. The comparison between diesel and WCO biodiesel blends has been made in terms of PM characterization which is PM mass concentration, its component ( soluble organic fraction (SOF) and soot) and its influence on PM formation, PM morphology and PM size distribution. In addition, combustion characteristic which is in-cylinder pressure of the engine as well as exhaust temperature also has been observed. The results show PM emission of B100 is lower than diesel fuel with variation of 5.56% to 21.82 % . This is due to oxygen content contained in B100. As for SOF concentration, blended fuels B10, B20, and B100 have higher SOF value (3.23 % to 82.36 % ) compared to diesel fuel at moderate and high engine speed. Meanwhile, soot concentration for blended fuels B10, B20 and B100 is lower (10 % to 62.50 %. ) compared to diesel fuel Observation on PM morphology shows that the images is chain-like agglomeration which is extremely small non uniform nanostructure. As for the PM size distribution, the trend were similar for diesel and WCO biodiesel blends. The size distribution of diesel fuel and WCO biodiesel blends were shifted to the larger size as the engine speed is increase d. Simultaneously, the size distribution is shifted to the smaller PM diameter as blending ratio of WCO biodiesel in the fuel blend is increase. The observation of in-cylinder pressure shows uncertain trend with the WCO biodiesel ratio in the fuel blend while decreasing with the increasing engine speed due to the prolong ignition delay period. At the same time, WCO biodiesel blends gives higher value of exhaust temperature which is 1.49 % compared to diesel fuel and it increases as the engine speed increase. In terms of gaseous emission, increasing engine speed increased the CO, CO2, NOx and NO emission while decrease the O2emission. The effect of WCO biodiesel blends on the gaseous emission shows uncertain trend while PM-NOx trade off observation showsB100 simultaneously decrease both NOx and PM emission at the same time. This study shows that the PM and gaseous emission as well as combustion characteristic of the WCO biodiesel are comparable with diesel fuel thus WCO biodiesel has potential as an alternative fuel to be used in diesel in the future.

This book was released on 2015-06-04 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of the IARC Monographs provides evaluations of the carcinogenicity of diesel and gasoline engine exhausts, and of 10 nitroarenes found in diesel engine exhaust: 3,7-dinitrofluoranthene, 3,9-dinitrofluoranthene, 1,3-dinitropyrene, 1,6-dinitropyrene, 1,8-dinitropyrene, 6-nitrochrysene, 2-nitrofluorene, 1-nitropyrene, 4-nitropyrene, and 3-nitrobenzanthrone. Diesel engines are used for transport on and off roads (e.g. passenger cars, buses, trucks, trains, ships), for machinery in various industrial sectors (e.g. mining, construction), and for electricity generators, particularly in developing countries. Gasoline engines are used in cars and hand-held equipment (e.g. chainsaws). The emissions from such combustion engines comprise a complex and varying mixture of gases (e.g. carbon monoxide, nitrogen oxides), particles (e.g. PM10, PM2.5, ultrafine particles, elemental carbon, organic carbon, ash, sulfate, and metals), volatile organic compunds (e.g. benzene, formaldehyde) and semi-volatile organic compounds (e.g. polycyclic aromatic hydrocarbons) including oxygenated and nitrated derivatives of polycyclic aromatic hydrocarbons. Diesel and gasoline engines thus make a significant contribution to a broad range of air pollutants to which people are exposed in the general population as well as in different occupational settings. An IARC Monographs Working Group reviewed epidemiological evidence, animal bioassays, and mechanistic and other relevant data to reach conclusions as to the carcinogenic hazard to humans of environmental or occupational exposure to diesel and gasoline engine exhausts (including those associated with the mining, railroad, construction, and transportation industries) and to 10 selected nitroarenes. -- Back cover.

Book excerpt: This third volume of the handbook presents a representative sample of the population papers in the field of petrodiesel fuels. Following the substantial public concerns on the adverse impact of the emissions from petrodiesel fuels on the environment and human health, the research has intensified in the areas related to the reduction of these adverse effects. Thus, bioremediation of spills from crude oils and petrodiesel fuels at sea and soils as well as desulfurization of petrodiesel fuels have emerged as publicly important research areas. Similarly, the emissions from diesel fuel exhausts, due to their adverse effects on both human health and environment, have been researched more in recent years. These emissions cover particulate emissions, aerosol emissions, and NOx emissions. Research on the adverse impact of petrodiesel fuel exhaust emissions on human health has primarily progressed along the lines of respiratory illnesses, cancer, and other illnesses, such as cardiovascular illnesses, brain illnesses, and reproductive system illnesses, through human, animal, and in vitro studies. It is clear that these illnesses caused by the petrodiesel fuel exhaust emissions have been one of the most significant reasons to develop alternative biodiesel fuels. Part IX presents a representative sample of the population papers in the field of crude oils covering major research fronts. It covers crude oil spills in general, crude oil spills and their cleanup, properties and removal of crude oils, biodegradation of crude oil-contaminated soils, and crude oil recovery besides an overview paper. Part X presents a representative sample of the population papers in the field of petrodiesel fuels in general covering major research fronts. It covers combustion of biodiesel fuels in diesel engines, bioremediation of biodiesel fuel-contaminated soils, biodiesel power generation, and desulfurization of diesel fuels besides an overview paper. Part XI presents a representative sample of the population papers in the field of emissions from petrodiesel fuels covering major research fronts. It covers diesel emission mitigation, diesel particulate emissions, and diesel NOx emissions, besides an overview paper. Part XII presents a representative sample of the population papers in the field of the health impact of the emissions from petrodiesel fuels covering major research fronts. It covers respiratory illnesses, cancer, cardiovascular, brain, and reproductive system illnesses, besides an overview paper.

Available in PDF, EPUB and Kindle. Book excerpt: This book explains, compares and assesses the legal implications of Dieselgate within a range of selected jurisdictions and at the EU, international and comparative law level.The book analyses the US EPA-VW $14.7 billion dollar settlement of 2016, one of the largest civil settlements in the history of environmental law. As it shows, the Dieselgate affair has raised a host of issues concerning corporate and social responsibility, tort liability, environmental liability, contractual defective products, warranty, and false environmental claims in a range of jurisdictions. Issues like repurchasing or retrofitting cars from consumers and making direct payments to consumers through car buy-backs and compensation are analysed. Further, the book relates how Dieselgate has also contributed to the discussion about the introduction of more effective collective measures of redress for consumers, such as class actions, in Germany, France, Italy and the UK.The book subsequently reviews the criminal offences Volkswagen is currently confronted with in Germany, France and Italy, i.e. fraud and manipulation of capital markets (by belatedly providing shareholders with essential information relevant for the share value), and, potentially, environmental crimes. It demonstrates how Dieselgate has sparked new debates in Germany, Italy, France and the UK about the need to introduce enterprise liability for organised crimes, lack of compliance and control structures, and intentional violations of the law.Lastly, the book discusses how EU law has sought to respond to Dieselgate and thus investigates the controversial EU Regulation No. 2016/646 introducing a "temporary conformity factor" of 2.1 (equivalent to a 110% increase on the current limit) to be applied for NOx in the new RDE testing cycle, and the works of the EU committee of inquiry into Emissions Measurements in the Automotive Sector (EMIS).

Download or read book The Effects of Oxidized Biodiesel Fuel on Fatty Acid Methyl Ester Composition and Particulate Matter Emissions From a Light Duty Diesel Engine written by Jack Elliot Reed and published by . This book was released on 2021 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diesel particulate matter (PM) is classified by the EPA as carcinogenic, with the transportation sector largely responsible these emissions within the United States. Biodiesel (B100) is derived from renewable sources, providing similar chemical composition to diesel fuel and is in the current diesel supply up to 5% across the nation. However, biodiesel has an inherent oxidation issue due to the unique mixture of fatty acid methyl ester (FAME) molecules present in the biodiesel that are not in diesel. Biodiesel oxidation can only be delayed, and the inevitable process results in changes to the original fuel composition that may alter emissions profiles. There have been limited studies on the effect of oxidized biodiesel fuel on PM emissions, and with increasing biodiesel production volumes, it is important to assess due to possible adverse human health effects. In this study, it was hypothesized that the change in fuel composition due to oxidation would lead to lower PM emissions because the presence of more fuel oxygen molecules and secondary oxidation products would enhance self-combustion characteristics. In this study, PM mass generated from a light-duty diesel engine running on three different fuel types--pure ("neat") B100 biodiesel, pure B0 diesel, and B20 (20% v/v biodiesel blend with diesel)--was quantified and compared to the PM mass (and concentrations) from repeated emissions testing using artificially oxidized B100 and B20 biodiesel as the fuel source. B100 fuel was heated at 110oC for 5, 10, and 20 hours ("oxidation states" 3, 2, and 1, respectively), verifying the extent of fuel oxidation by building an apparatus (Biodiesel Oxidation Stability Surveyor, BOSS) that quantified the biodiesel fuel's oxidative stability using a method equivalent to standard methods for determining the biofuel's induction period. Induction period increased linearly with time spent under the artificial oxidation conditions. A custom, load-based steady-state modal drive cycle was specially developed for emissions testing each neat and oxidized B100 and B20 fuel type in a light-duty diesel engine dynamometer. Observed changes in PM mass with increased fuel oxidation time occurred only for B20 fuel with a 51 ±13% decrease. Fuel properties such as cetane number, biodiesel content, density, and total aromatics were compared between neat and oxidized B20 and B100 samples. Cetane number increased 7% from 66.8 to 71.7 from B100 neat to B100 OX1 (20hrs) and density increased from 0.709g/cm3 to 0.723g/cm3. Chemical analysis of the biodiesel fuels by gas chromatography mass spectrometry (GCMS) quantified individual FAME compounds to determine key species involved in fuel oxidation. B100 FAME concentration widely varied, however, the B20 fuel blend showed that 20 hour artificial oxidation treatment decreased concentrations of the unsaturated FAMEs for C18:3n3, C18:2 cis-9,12, C18:1 (both cis- and trans- isomers) by 41.7 ±3.5%, 33.25 ±8.8%, and 21.9 ±6.9% relative to their initial concentration in the unoxidized fuel, respectively, in general agreement with literature values. The findings of this study help contribute a better understanding of oxidation effects on biodiesel fuel and link together fuel properties, chemical composition, and particulate emissions whereas most literature excludes detailed analysis of biodiesel fuel composition and associated emissions effects.
