This book was released on 2020-07-20 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of the multi-dimensional approach for the production of ethanol from lignocellulosic biomass. The sustainability of this biofuel, the current and future status of the technology and its role in waste valorization are also addressed. Bioethanol from lignocellulosic material has emerged as an alternative to the traditional first-generation bioethanol. The book also discusses various pretreatment methods for effective separation of the various components of lignocellulosic feedstock as well as their advantages, and limitations. It describes the valorization of lignocellulosic waste through the production of bioethanol and emphasizes the significance of waste utilization in managing the production cost of the fuel. Finally, the utilization of genetically engineered plants and microorganisms to increase the conversion efficiency is reviewed.

Available in PDF, EPUB and Kindle. Book excerpt: Bioethanol has been recognized as a potential alternative to petroleum-derived transportation fuels. Even if cellulosic biomass is less expensive than corn and sugarcane, the higher costs for its conversion make the near-term price of cellulosic ethanol higher than that of corn ethanol and even more than that of sugarcane ethanol. Conventional process for bioethanol production from lignocellulose includes a chemical/physical pre-treatment of lignocellulose for lignin removal, mostly based on auto hydrolysis and acid hydrolysis, followed by saccharification of the free accessible cellulose portions of the biomass. The highest yields of fermentable sugars from cellulose portion are achieved by means of enzymatic hydrolysis, currently carried out using a mix of cellulases from the fungus Trichoderma reesei. Reduction of (hemi)cellulases production costs is strongly required to increase competitiveness of second generation bioethanol production. The final step is the fermentation of sugars obtained from saccharification, typically performed by the yeast Saccharomyces cerevisiae. The current process is optimized for 6-carbon sugars fermentation, since most of yeasts cannot ferment 5-carbon sugars. Thus, research is aimed at exploring new engineered yeasts abilities to co-ferment 5- and 6-carbon sugars. Among the main routes to advance cellulosic ethanol, consolidate bio-processing, namely direct conversion of biomass into ethanol by a genetically modified microbes, holds tremendous potential to reduce ethanol production costs. Finally, the use of all the components of lignocellulose to produce a large spectra of biobased products is another challenge for further improving competitiveness of second generation bioethanol production, developing a biorefinery.
Download or read book Next Generation Biofuels written by William T. Coyle and published by DIANE Publishing. This book was released on 2010 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Assesses the short-term outlook for production of next-generation biofuels and the near-term challenges facing the sector. Next-generation U.S. biofuel capacity should reach about 88 mill. gal. in 2010, thanks to one plant becoming commercially operational in 2010, using non-cellulosic animal fat to produce green diesel. U.S. production capacity for cellulosic biofuels is estimated to be 10 mill. gal. for 2010, much less than the 100 mill. gal. originally mandated in 2007. Near-term sector challenges include reducing high capital and production costs, acquiring financial resources for pre-commercial development, developing new biomass supply arrangements, and overcoming the constraints of ethanol¿s current 10-percent blending limit with gasoline.

Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive coverage on the growing science and technologyof producing ethanol from the world's abundant cellulosicbiomass The inevitable decline in petroleum reserves and its impact ongasoline prices, combined with climate change concerns, havecontributed to current interest in renewable fuels. Bioethanol isthe most successful renewable transport fuel—with corn andsugarcane ethanol currently in wide use as blend-in fuels in theUnited States, Brazil, and a few other countries. However, thereare a number of major drawbacks in these first-generation biofuels,such as their effect on food prices, net energy balance, and poorgreenhouse gas mitigation. Alternatively, cellulosic ethanol can beproduced from abundant lignocellulosic biomass forms such asagricultural or municipal wastes, forest residues, fast growingtrees, or grasses grown in marginal lands, and should be produciblein substantial amounts to meet growing global energy demand. The Handbook of Cellulosic Ethanol covers all aspects ofthis new and vital alternative fuel source, providing readers withthe background, scientific theory, and recent research progress inproducing cellulosic ethanol via different biochemical routes, aswell as future directions.

Download or read book Evaluation of Feedstocks for Cellulosic Ethanol and Bioproducts Production in the Northwest written by Wesley Clair Miller and published by . This book was released on 2011 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cellulosic ethanol production for transportation fuel is one source to help satisfy the increasing worldwide demand for energy and depletion of the fossil fuel supply. Evaluating potential production from plants and waste in Oregon, Washington and Idaho is the purpose of this study. Reed Canary grass, Annual Ryegrass, wheat straw, corn cobs, corn pericarp, gorse and waste newspaper are studied. Except for the newspaper (an analogue of municipal solid waste), these are common agricultural crops or invasive plants which are adapted to this area, and most of the United States. This paper estimates the potential for production of ethanol from these feedstocks through an investigation of available cropland combined with laboratory research into ethanol yield from these materials. Laboratory data for the various feedstocks ranged up to 237kg/Mg (72 gallons/ton) of ethanol produced. Total Northwest cropland is 7,502,272 hectares (18,538,517 acres) with 2,638,955 hectares (6,520,793 acres) of that under irrigation. (2007 Census of Agriculture - County Data, 2008). Common gorse, Ulex europaeus L., was examined for amounts of ether, hexane, ethanol and steam extracts and cellulosic ethanol yield at different times of the year. The highest seasonal amount of each component was approximately double that of the lowest.
Download or read book Renewable Fuel Standard written by National Research Council and published by National Academies Press. This book was released on 2012-01-29 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the United States, we have come to depend on plentiful and inexpensive energy to support our economy and lifestyles. In recent years, many questions have been raised regarding the sustainability of our current pattern of high consumption of nonrenewable energy and its environmental consequences. Further, because the United States imports about 55 percent of the nation's consumption of crude oil, there are additional concerns about the security of supply. Hence, efforts are being made to find alternatives to our current pathway, including greater energy efficiency and use of energy sources that could lower greenhouse gas (GHG) emissions such as nuclear and renewable sources, including solar, wind, geothermal, and biofuels. The United States has a long history with biofuels and the nation is on a course charted to achieve a substantial increase in biofuels. Renewable Fuel Standard evaluates the economic and environmental consequences of increasing biofuels production as a result of Renewable Fuels Standard, as amended by EISA (RFS2). The report describes biofuels produced in 2010 and those projected to be produced and consumed by 2022, reviews model projections and other estimates of the relative impact on the prices of land, and discusses the potential environmental harm and benefits of biofuels production and the barriers to achieving the RFS2 consumption mandate. Policy makers, investors, leaders in the transportation sector, and others with concerns for the environment, economy, and energy security can rely on the recommendations provided in this report.
Download or read book Bioalcohol Production written by Keith W. Waldron and published by Elsevier. This book was released on 2010-05-24 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioethanol is one of the main biofuels currently used as a petroleum-substitute in transport applications. However, conflicts over food supply and land use have made its production and utilisation a controversial topic. Second generation bioalcohol production technology, based on (bio)chemical conversion of non-food lignocellulose, offers potential advantages over existing, energy-intensive bioethanol production processes. Food vs. fuel pressures may be reduced by utilising a wider range of lignocellulosic biomass feedstocks, including energy crops, cellulosic residues, and, particularly, wastes.Bioalcohol production covers the process engineering, technology, modelling and integration of the entire production chain for second generation bioalcohol production from lignocellulosic biomass. Primarily reviewing bioethanol production, the book's coverage extends to the production of longer-chain bioalcohols which will be elemental to the future of the industry.Part one reviews the key features and processes involved in the pretreatment and fractionation of lignocellulosic biomass for bioalcohol production, including hydrothermal and thermochemical pretreatment, and fractionation to separate out valuable process feedstocks. Part two covers the hydrolysis (saccharification) processes applicable to pretreated feedstocks. This includes both acid and enzymatic approaches and also importantly covers the development of particular enzymes to improve this conversion step. This coverage is extended in Part three, with chapters reviewing integrated hydrolysis and fermentation processes, and fermentation and co-fermentation challenges of lignocellulose-derived sugars, as well as separation and purification processes for bioalcohol extraction.Part four examines the analysis, monitoring and modelling approaches relating to process and quality control in the pretreatment, hydrolysis and fermentation steps of lignocellulose-to-bioalcohol production. Finally, Part five discusses the life-cycle assessment of lignocellulose-to-bioalcohol production, as well as the production of valuable chemicals and longer-chain alcohols from lignocellulosic biomass.With its distinguished international team of contributors, Bioalcohol production is a standard reference for fuel engineers, industrial chemists and biochemists, plant scientists and researchers in this area. - Provides an overview of the life-cycle assessment of lignocelluloses-to-bioalcohol production - Reviews the key features and processes involved in the pre-treatment and fractionation of lignocellulosic biomass for bioalcohol production - Examines the analysis, monitoring and modelling approaches relating to process and quality control in pre-treatment, hydrolysis and fermentation
