This book was released on 2020-03-23 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Production and utilization of sustainable energy toward maintaining a clean environment is a major challenge. At the same time, the continued depletion of fossil fuels and the global dependency on non-renewable fuels is a chief concern. Moreover, the long-term economic and environmental issues associated with the high utilization of fossil fuel, such as global warming, are also important, particularly in the context of the predicted increase in the global population to around 5 billion by 2050. In recent years, researchers have been investigating alternative, renewable fuels to replace fossil fuels. Of the various options, biofuels are especially attractive due to their low production costs and the fact that they are pollution free. Also known as transportation fuels, their energy is derived from biological resources or through the biological processes. Biofuels such as biohydrogen, biomethane, biogas, ethanol and butanol offer a number of advantages and can be economically produced from cellulosic biomass. As such, they can play a vital role in sustainably meeting future energy demands. Biofuels have the potential to become a global primary energy source, offering significant reductions in greenhouse gas emissions as well as opportunities to increase economic and social development in rural communities and reduce the problems associated with waste disposal. However, low yields and lack of process technology are some of the aspects that need to be addressed. This book offers an overview of existing biofuels and the technologies to solve the problems associated with their practical implementation. Evaluating the biofuel options and discussing the opportunities and risks in relation to resources, technologies, practices, markets and policy, it provides insights into the development of economically viable bioenergy industries.

Available in PDF, EPUB and Kindle. Book excerpt: From basic tenets to the latest advances, this is the most comprehensive and up-to-date coverage of the process of biodesulfurization in the petroleum refining industry. Petroleum refining and process engineering is constantly changing. No new refineries are being built, but companies all over the world are still expanding or re-purposing huge percentages of their refineries every year, year after year. Rather than building entirely new plants, companies are spending billions of dollars in the research and development of new processes that can save time and money by being more efficient and environmentally safer. Biodesulfurization is one of those processes, and nowhere else it is covered more thoroughly or with more up-to-date research of the new advances than in this new volume from Wiley-Scrivener. Besides the obvious benefits to biodesulfurization, there are new regulations in place within the industry with which companies will, over the next decade or longer, spend literally tens, if not hundreds, of billions of dollars to comply. Whether for the veteran engineer needing to update his or her library, the beginning engineer just learning about biodesulfurization, or even the student in a chemical engineering class, this outstanding new volume is a must-have. Especially it covers also the bioupgrading of crude oil and its fractions, biodenitrogenation technology and application of nanotechnology on both biodesulfurization and biodenitrogenation technologies.

Download or read book Algae and Environmental Sustainability written by Bhaskar Singh and published by Springer. This book was released on 2015-12-22 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the dynamic role of algae in a sustainable environment. Two major aspects, namely bioenergy and bioremediation, have been elaborated in various chapter contributed by scientists and teachers from different geographical areas throughout the world. Algal biofuels is an emerging area of equal interest to researchers, industries, and policy makers working or focusing on alternative (i.e. renewable) fuels. Algae have been an area of interest due to their wide range of applications. Over the last 5 decades, eukaryotic algae have been used in the aquaculture industry as feed for invertebrates, providing a rich source of antioxidants, dietary fiber, minerals and protein. More recently, there has been a focus on the use of algal biomass in the development of alternative fuels. The extraction of oil from algae has been widely explored as a much more viable feedstock than plant-based oils in large-scale fuel production. using algae as feedstock has the advantages that it doesn’t require arable land and that wastewater can be used as a source of nutrients in their culture. The multifunctional approach of algae includes pollution remediation, carbon sequestration, biofuels production, and delivery of value-added products. However, there are still some obstacles that need to be overcome to make their use as potential feedstock for biofuels techno-economically feasible. In order to maintain the sustainability aspect of algal biofuels, various aspects have to be studied and critically analyzed to assess the long-term sustainability of algal derived biofuels. This book discusses the role of algae as a promising future feedstock for biofuels. They are known to sequester carbon in much larger amounts than plants and as such the book also describes their phycoremediation potential for conventional as well as emerging contaminants. It describes the role of anaerobic digestion in algal biorefineries; bioreactions and process parameters; biogas recovery and reuse. The role of algal biofilm based technology in wastewater treatment and transforming waste into bio-products is discussed, and remediation of sewage water through algae is assessed. The book also describes the production of biohydrogen, bio-oil, biodiesel; and the major bottlenecks in their usage. The emerging characterization techniques of these biofuels (bio-oil and biodiesel) are described, as are the decolorizing potential of algae and the genetic engineering techniques that could enhance the production of lipids in algae. Other aspects of the book include the role of remote sensing technology in the monitoring of algae and a life cycle assessment of algal biofuels.

Download or read book Anaerobic Digestion of Yard Waste and Biogas Purification by Removal of Hydrogen Sulfide written by Phil Boone Cherosky and published by . This book was released on 2012 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Lignocellulosic biomass feedstocks, in particular yard waste, are highly desired for anaerobic digestion as they are widely available and tipping fees are commonly associated with disposal. The high concentration of lignin presents a major challenge for utilizing yard wastes as a feedstock for anaerobic digestion. Therefore, additional steps are necessary to increase the biodegradability of yard waste. The initial focus of this study was to test two potential methods for increasing the methane production of yard waste: pretreatment and co-digestion. Sodium hydroxide (NaOH) pretreatment was studied at NaOH concentrations of 3% and 5%. It was found that 3% NaOH pretreatment had no significant improvement on methane production while 5% NaOH pretreatment had a significant negative effect on methane production. The second method studied was co-digestion of yard waste and food waste. Co-digestion at a ratio of 75% food waste and 25% yard waste showed a four-fold increase in methane yield compared to digestion of 50% food waste and 50% yard waste and a two-fold increase in methane production compared to digestion of 100% food waste. Anaerobic digestion of food waste containing protein and other sulfur containing substances produces hydrogen sulfide in biogas. Hydrogen sulfide (H2S) in biogas causes corrosion of metal components such as regulators, gas meters, valves, and mountings. Combustion of biogas containing H2S produces poisonous sulfur dioxide (SO2). The SO2 also dissolves in engine oil causing the oil to become acidic and lose its ability to lubricate. One method for H2S removal involves using hydrated iron oxides supported on a media comprised of wood chips or wood shavings. The iron oxide reacts with the H2S in the gas to form iron sulfide and water. This method is called an iron sponge. The second focus of this study was to test hydrogen sulfide removal using the iron sponge method. The first goal was to determine the optimum operating parameters of an iron sponge system. Using ground yard waste, ideal operating parameters for the iron sponge were determined to be 0.1875" particle size and 15%-25% moisture content. Moisture was found to be a critical factor in the operation of the H2S scrubber system. Optimum moisture content varies with particle size and the materials' ability to absorb water. The iron sponge needs water to properly facilitate H2S conversion to Fe2S3, but high moisture can be problematic. The second and primary goal of this research was to develop and test iron sponge materials using alternative media to the commercial material, SulfaMasterTM, and to identify those with equal or superior performance. An iron sponge using digested yard waste from an anaerobic digester as a media material at 25% moisture was determined to be an ideal alternative to the SulfaMasteTM material removing 90% of the hydrogen sulfide in biogas at initial levels near 1000ppm H2S. The digested yard waste had similar performance to SulfaMasterTM and is an inexpensive substitute. Ground yard waste at 0.1875" particle size performed similarly but results were more erratic. Spent tobacco was not an effective medium for the iron sponge.
