This book was released on 2012-12-06 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2012 in the subject Engineering - Chemical Engineering, Addis Ababa University, language: English, abstract: Lignocellulosic materials (eg.Prosopis juliflora) can be utilized to produce ethanol, a promising alternative energy source for the limited crude oil. This study involved optimisation of acid hydrolysis in ethanol production from prosopis juliflora. The conversion of prosopis juliflora to ethanol can be achieved mainly by three process steps: pretreatment of prosopis juliflora wood to remove lignin and hemicellulose, acid hydrolysis of pretreated prosopis juliflora to convert cellulose into reducing sugar(glucose) and fermentation of the sugars to ethanol using Saccharomyces cerevisiae in anaerobic condition. A two level full factorial design with four factors, two levels and two replicas (24*2=32 experimental runs) was applied to optimize acid hydrolysis and study the interaction effects of acid hydrolysis factors, namely, acid concentration, solid fraction, temperature, and time. An optimization was carried out to optimize acid hydrolysis process variables so as to determine the best acid concentration, solid fraction, temperature, and contact time that resulted maximum ethanol yield. The screening of significant acid hydrolysis factors were done by using the two-level full factorial design using design expert® 7 software. The statistical analysis showed that the ethanol yield of (40.91% (g/g)) was obtained at optimised acid hydrolysis variables of 0.5%v/v acid concentration, 5%w/w solid fraction,105.01°C temperature, and 10 minutes hydrolysis time. Keywords: Prosopis juliflora, pretreatment, hydrolysis, fermentation, 2 level factorial, optimization.

Download or read book High temperature Acid Hydrolysis of Cellulose for Alcohol Fuel Production written by John D. Wright and published by . This book was released on 1983 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents parametric analyses of high temperature dilute acid hydrolysis of cellulosic feedstocks for the production of ethanol fuels. The chemical and physical structure of cellulosic feedstocks is described, and their influence on the hydrolysis reactions explained. The rationale for the acid hydrolysis process is presented, and the steps described in detail. Hydrolysis kinetics are discussed in detail and illustrated graphically. Large reductions in the price of ethanol are possible, as improvements are made in presently available processes. Increasing the solids concentration in the reactor feed causes the largest reduction in sales price.

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. The seventeen chapters includeinformation on: Advantages of cellulosic ethanol over first-generation ethanolas a transportation fuel Various biomass feedstocks that can be used to make cellulosicethanol Details of the aqueous phase or cellulolysis route,pretreatment, enzyme or acid saccharification, fermentation,simultaneous saccharification fermentation, consolidatedbioprocessing, genetically modified microorganisms, and yeasts Details of the syngas fermentation or thermochemical route,gasifiers, syngas cleaning, microorganisms for syngas fermentation,and chemical catalysts for syngas-to-ethanol conversion Distillation and dehydration to fuel-grade ethanol Techno-economical aspects and the future of cellulosicethanol Readership Chemical engineers, chemists, and technicians working onrenewable energy and fuels in industry, research institutions, anduniversities. The Handbook can also be used by studentsinterested in biofuels and renewable energy issues.

Available in PDF, EPUB and Kindle. Book excerpt: This book offers a broad understanding of bioethanol production from sugarcane, although a few other substrates, except corn, will also be mentioned. The 10 chapters are grouped in five sections. The Fuel Ethanol Production from Sugarcane in Brazil section consists of two chapters dealing with the first-generation ethanol Brazilian industrial process. The Strategies for Sugarcane Bagasse Pretreatment section deals with emerging physicochemical methods for biomass pretreatment, and the non-conventional biomass source for lignocellulosic ethanol production addresses the potential of weed biomass as alternative feedstock. In the Recent Approaches for Increasing Fermentation Efficiency of Lignocellulosic Ethanol section, potential and research progress using thermophile bacteria and yeasts is presented, taking advantage of microorganisms involved in consolidating or simultaneous hydrolysis and fermentation processes. Finally, the Recent Advances in Ethanol Fermentation section presents the use of cold plasma and hydrostatic pressure to increase ethanol production efficiency. Also in this section the use of metabolic-engineered autotrophic cyanobacteria to produce ethanol from carbon dioxide is mentioned.
