This book was released on 2015 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diesel engines are attractive power units that are used widely in many fields and have become one of the larger contributors of total petroleum consumption. However, diesel engines are among the main contributors to emissions into the air, especially particulate matter (PM) and nitrogen oxides (NOx). PM is one of the major pollutants emitted by diesel engines and has adverse effects on human health. However, not many studies have been conducted on the PM concentration and PM morphological and size distribution on biodiesel fuel. Biodiesel, which produces less PM than diesel fuel, is preferred as an alternative source for diesel engines. Therefore, using palm oil methyl ester (POME) for diesel engines would be a more economical and sustainable solution. The objective of this research is to study the PM emissions characteristic from diesel engines fuelled with a diesel and POME blend. A transmission electron microscope (TEM) was used to determine the aggregate fractal prefactor, spherule, and aggregate size distribution. A comparison between diesel and the POME blend was made in terms of PM characterization, which involves PM mass concentration, its components soluble organic fraction (SOF) and dry soot (DS), and its influence on PM morphology such as spherule and aggregate correlation. Combustion characteristics such as in-cylinder pressure and rate of heat release of the engine as well as gaseous emissions were also observed at different operating engine loads. The results show that PM emissions of B100 are lower than those of diesel fuel owing to the oxygen content of POME. Observations of images on PM morphology showed a chainlike agglomeration, which is an extremely small non-uniform nanostructure. Simultaneously, the aggregate size distribution shifted to a smaller diameter as the blending ratio of POME in the fuel increased. The observation of in-cylinder pressure showed that the increment of pressure with the increasing POME blend as well as the increasing engine load is due to high cetane number for B100 that led to a shorten ignition delay. The engine brake thermal efficiency between the POME blend and mineral diesel was comparable. Furthermore, B100 fuels showed lower engine power at higher brake-specific fuel consumption compared to other tested fuels. In terms of gaseous emissions, increasing POME blends led to an increase in CO2 and NOx while decreasing CO emission. Meanwhile, as the engine load increased, CO2, NOx and CO also continued to increase. The effect of the POME blend on the PM-NOx trade-off observation showed that B100 simultaneously increased the NOx and decreased the PM emission. Both the wavelet analysis and coefficient of variation revealed that increasing the POME ratio provided a noticeable effect on increasing the engine cycle-to-cycle variations. It can be concluded that POME creates lower PM concentration while giving some negative feedback to NOx and resulting in smaller particle size. Moreover, the findings reveal that by having the wavelet analysis, one can predict the behavior of the PM emissions and subsequently further research helps to reduce them effectively and economically.

This book was released on 2009 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this research has been to investigate how the oxidation characteristics of diesel particulate matter (PM) are affected by blending soy-based biodiesel fuel with conventional ultra low sulfur diesel (ULSD) fuel. PM produced in a light duty engine from different biodiesel-conventional fuel blends was subjected to a range of physical and chemical measurements in order to better understand the mechanisms by which fuel-related changes to oxidation reactivity are brought about. These observations were then incorporated into a kinetic model to predict PM oxidation. Nanostructure of the fixed carbon was investigated by HR-TEM and showed that particulates from biodiesel had a more open structure than particulates generated from conventional diesel fuel, which was confirmed by BET surface area measurements. Surface area evolution with extent of oxidation reaction was measured for PM from ULSD and biodiesel. Biodiesel particulate has a significantly larger surface area for the first 40% of conversion, at which point the samples become quite similar. Oxidation characteristics of nascent PM and the fixed carbon portion were measured by temperature programmed oxidation (TPO) and it was noted that increased biodiesel blending lowered the light-off temperature as well as the temperature where the peak rate of oxidation occurred. A shift in the oxidation profiles of all fuels was seen when the mobile carbon fraction was removed, leaving only the fixed carbon, however the trend in temperature advantage of the biofuel blending remained. The mobile carbon fraction was measured by temperature programmed desorption found to generally increase with increasing biodiesel blend level. The relative change in the light-off temperatures for the nascent and fixed carbon samples was found to be related to the fraction of mobile carbon. Effective Arrhenius parameters for fixed carbon oxidation were directly measured with isothermal, differential oxidation experiments. Normalizing the reaction rate to the total carbon surface area available for reaction allowed for the definition of a single reaction rate with constant activation energy (112.5 ± 5.8 kJ/mol) for the oxidation of PM, independent of its fuel source. A kinetic model incorporating the surface area dependence of fixed carbon oxidation rate and the impact of the mobile carbon fraction was constructed and validated against experimental data.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Biomass can be used to produce renewable electricity, thermal energy, transportation fuels (biofuels), and high-value functional chemicals. As an energy source, biomass can be used either directly via combustion to produce heat or indirectly after it is converted to one of many forms of bioenergy and biofuel via thermochemical or biochemical pathways. The conversion of biomass can be achieved using various advanced methods, which are broadly classified into thermochemical conversion, biochemical conversion, electrochemical conversion, and so on. Advanced development technologies and processes are able to convert biomass into alternative energy sources in solid (e.g., charcoal, biochar, and RDF), liquid (biodiesel, algae biofuel, bioethanol, and pyrolysis and liquefaction bio-oils), and gaseous (e.g., biogas, syngas, and biohydrogen) forms. Because of the merits of biomass energy for environmental sustainability, biofuel and bioenergy technologies play a crucial role in renewable energy development and the replacement of chemicals by highly functional biomass. This book provides a comprehensive overview and in-depth technical research addressing recent progress in biomass conversion processes. It also covers studies on advanced techniques and methods for bioenergy and biofuel production.
