This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Petroleum prices have made alternative fuel crops a viable option for ethanol production. Sweet sorghum [Sorghum bicolor] is a non-food crop that may produce large quantities of ethanol with minimal inputs. Eleven cultivars were planted in 2008 and 2009 as a half-season crop. Four-row plots 6.9 m by 0.5 m, were monitored bimonthly for °Brix, height, and sugar accumulation. Yield and extractable sap were taken at the end of season. Stalk yield was greatest for the cultivar Sugar Top (4945 kg ha -1) and lowest for Simon (1054 kg ha−1). Dale ranked highest ethanol output (807 L ha−1) while Simon (123 L ha−1) is the lowest. All cultivars peak Brix accumulation occurs in early October. Individual sugar concentrations indicated sucrose is the predominant sugar with glucose and fructose levels dependent on cultivar. Supplemental ethanol in fermented wort was the best preservative tested to halt degradation of sorghum wort.

This book was released on 2012-12-06 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 28 (thesis year 1 983) a total of 10,661 theses titles from 26 Canadian and 197 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 28 reports theses submitted in-1983, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
Download or read book Lignocellulose Conversion written by Vincenza Faraco and published by Springer Science & Business Media. This book was released on 2013-06-12 with total page 207 pages. 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 Introduction to Biomass Energy Conversions written by Sergio Capareda and published by CRC Press. This book was released on 2013-07-09 with total page 649 pages. Available in PDF, EPUB and Kindle. Book excerpt: The potential that biomass energy has to supplement traditional fuels and reduce greenhouse gas emissions has put it front and center in the plan to replace fossil-based fuels with renewable fuels. While much has been written about biomass conversions, no single textbook contains all the information needed to teach a biomass conversion course—until now. Introduction to Biomass Energy Conversions presents a comprehensive review of biomass resources available for conversion into heat, power, and biofuels. The textbook covers biomass characterization and discusses facilities, equipment, and standards (e.g. ASTM or NREL) used for analysis. It examines the range of biomass resources available for conversion and presents traditional biomass conversion processes along with extensive biomass characterization data tables, illustrations, and graphical presentations of the various biomass energy conversion processes. The author also describes how to set up a laboratory for biomass energy conversion, and presents economics and sustainability issues. Loaded with real-world examples, the text includes numerous worked examples and problems in each chapter. No one knows what the price of oil will be next year or in future decades. It is governed by many factors other than supply and demand (politics, wars, etc.), however, whatever the future of energy is, bio-fuels will play an important role. This technical guide prepares students for managing bio-refineries, no matter what type of bio-fuel is produced. It also provides practicing engineers with a resource for starting a small bio-fuel business.

Download or read book Managing Sweet Sorghum for Optimum Ethanol Yield in Missouri written by Michael Joseph William Maw and published by . This book was released on 2013 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sweet sorghum has the potential in Missouri for production as a biofuel feedstock, but little is known of the crop's yields and appropriate nitrogen management for optimizing ethanol yields. This thesis is a collection of three field studies examining the potential for sweet sorghum (Sorghum bicolor (L.) Moench) to be adopted as a biofuel feedstock for ethanol production in the Midwestern U.S. Limited research exists examining the optimum nitrogen fertilizer rate for maximum ethanol yields as well as sweet sorghum's adaptability to the lower Midwestern states. The first study included testing the effects of five N fertilizer rates (0, 56, 112, 168, 224 kg-N ha-1) on the production of two sweet sorghum cultivars (Dale and Top 76-6) over three years in central Missouri. Yields measured included dry matter, stem juice, Brix, fermentable sugar, theoretical juice ethanol, theoretical lignocellulosic ethanol, and total theoretical ethanol. N fertilizer treatment mostly increased yields, as total dry matter yield averaged 16.8 Mg ha-1, fermentable sugar yield averaged 1055 kg ha-1, and total ethanol yield averaged 5828 L ha-1 . The optimal range for N fertilizer rates was between 112 and 168 kg N ha-1. The second study included determining the above-ground plant N concentration, plant N content, N recovery efficiency, and physiological N-use efficiency of sorghum from the first study. Nitrogen treatment significantly affected plant N concentration and N content. Greater yields resulted in greater N recovery efficiency but did not always result in greater N-use efficiency. The optimum range for highest nitrogen recovery and use efficiencies was identified as 0-112 kg N ha-1 . The purpose of the third study was to better understand sweet sorghum's affect on soil organic carbon. This involved comparing the effects of an alternative sweet sorghum--soybean (Glycine max L.) rotation to a maize (Zea mays L.)--soybean rotation at three study sites in Missouri and Arkansas on yields, soil organic carbon, the labile soil carbon fraction and the physically-stabilized fraction. Sweet sorghum ethanol yields were greater than maize yields across sites, but the soil carbon similarly decreased regardless of crop and location. Sweet sorghum is a high-yielding biomass feedstock that shows promise for production in Missouri, especially in marginal lands. With proper nitrogen fertilizer management sweet sorghum is shown to be an efficient plant for ethanol yield, but it may negatively affect soil organic carbon following land-use changes for biofuel production.

Download or read book Growing Sweet Sorghum as a Source of Fermentable Sugars for Energy written by Gary John Gascho and published by . This book was released on 1984 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies were conducted to evaluate the potential of sweet sorghum as a fuel ethanol feedstock for the southern coastal plain. Several cultural aspects were studied and a methol for rapid evaluation of the fermentable sugar concentrtions in the stalks was developed. The major findings of the studies were. 1. Wray, M81E, and MN1500 were the highest yielding early, medium, and late-maturing cultivars tested. Because of its high sugar concentration and resistance to lodging, Wray was the best single cultivar. 2. On the better agricultural soils of the area, the yield potential is five to six metric tons of total sugars per hectare. 3. The best planting time is in early May. Yields are reduced in plantings after mid-May because of early maturity and damage from the fall armyworm (Spodoptera frugiperda (J.E. Smith). The best harvest time is at the soft, to hard-dough stages of the seed. To maintain a constant supply of high-yielding sweet sorghum for a fuel ethanol plant, it was demonstrated the combinations of cultivars, planting dates, and harvest stages resulted in 95% of maximum sugar yield over a four-month period. 5. Nutrient requirements for sweet sorghum were low in comparisons to corn. No response to P or K was found when the soil test was high or medium for the elements, respectively. For a medium P soil test, yield responses were obtained to at least 25 kg P/ha. For a low K test, response was obtained to 186 kg K/ha. Response was obtained to about 100 kg N/ha. The N application should be split, with about one-half to two-thirds applied as a sidedressing when the sorghum is 30 to 60 cm high. No response was found to a 10-34-0 starter fertilizer, but the P soil test was high in this study. 6. The actual removal of nutrients by a sweet sorghum crop was determined to be 1,5 kg/MT fresh stalks for N, 0.3 for P, 1.8 for K, 0,6 for Ca and 0,3 for Mg. 7. No yield advantage was found in decreasing the row sapcing from 90 cm nor was there as advantage to increasing the population above 75 thousand plants per hectare. 8. The best control of annual grasses was obtained with a propazine plus metolachlor treatment. 9. No positive responses were found to the application of several growth regulators. 10. As automated analysis for determining the concentrations of total sugars in fresh or frozen sweet sorghum stalks was developed using an AutoAnalyzer II.
