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 Energy Analysis of Sweet Sorghum Ethanol Using a Bottom up Energy Return Ratio Matrix Approach written by John A. Veracruz and published by . This book was released on 2015 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Between 2012 and 2013 the world increased biofuel consumption by 6.1% and if forecasts hold, according to the International Energy Agency, by 2050 27% of the world’s transport energy will come from biofuels. Rather than succumb to a shortage of corn, alternative feedstocks must gain the same traction corn has gained within the ethanol production industry. When considering an alternative feedstock what must also be considered it is that energy output from ethanol production exceeds the energy needed to produce one liter of alcohol. With origins traced back to Africa, sweet sorghum, or Sorghum bicolor(L) Moench, has gained traction as a viable ethanol feedstock due to the plant’s ability to reach a harvest maturity in as little as four months. With similarities to that of sugarcane, sweet sorghum’s stalk contains a relatively balanced amount of both insoluble and soluble carbohydrates. Although sweet sorghum will flourish with the appropriate amount of water, its drought resistance provides versatility other ethanol feedstocks do not possess. However, lower inputs, drought resistance, and the ability to grow on fallow land are all meaningless if growers miss a relatively short harvesting window, or even worse, allow fermentable sugars to decay by not expediting fermentation. If sweet sorghum ethanol is to displace any amount of corn and prove its feedstock viability, its energy balance must show more energy is output than is input. By using a bottom-up matrix based approach using energy return rations (ERRs), a product’s system may be evaluated to determine its usefulness to society. The Brandt et al. framework requires the creation of two matrices; a technology matrix, A, and an intervention matrix, B. Devising information from these matrices requires the use of three main vectors which serve as the foundation for calculating the desired ERR. Using this method in conjunction with four ERRs allows the study of energy processes used to create inputs for sweet sorghum pathways and possibly allude to how this energy is used to eliminate waste or improve efficiency through cleaner energy sources.

Book excerpt: Governments are setting challenging targets to increase the production of energy and transport fuel from sustainable sources. The emphasis is increasingly on renewable sources including wind, solar, geothermal, biomass based biofuel, photovoltaics or energy recovery from waste. What are the environmental consequences of adopting these other sources? How do these various sources compare to each other? Life Cycle Assessment of Renewable Energy Sources tries to answer these questions based on the universally adopted method of Life Cycle Assessment (LCA). This book introduces the concept and importance of LCA in the framework of renewable energy sources and discusses the key issues in conducting their LCA. This is followed by an in-depth discussion of LCA for some of the most common bioenergy sources such as agricultural production systems for biogas and bioethanol, biogas from grass, biodiesel from palm oil, biodiesel from used cooking oil and animal fat, Jatropha biodiesel, lignocellulosic bioethanol, ethanol from cassava and sugarcane molasses, residential photovoltaic systems, wind energy, microalgal biodiesel, biohydrogen and biomethane. Through real examples, the versatility of LCA is well emphasized. Written by experts all over the globe, the book is a cornucopia of information on LCA of bioenergy systems and provides a platform for stimulation of new ideas and thoughts. The book is targeted at practitioners of LCA and will become a useful tool for researchers working on different aspects of bioenergy.
Download or read book Evaluation of Sweet Sorghum Cultivars as a Potential Ethanol Crop in Mississippi written by David Scott Horton (II) and published by . 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.
Download or read book Biofuel Production Technologies Critical Analysis for Sustainability written by Neha Srivastava and published by Springer Nature. 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: ABSTRACT: Biofuels are emerging as a potential replacement for fossil fuel derived liquid fuels and with increasing production rates is has become essential to understand the environmental and energetic impacts of their production. This study focuses on ethanol production from four feedstocks: corn, sweet sorghum, sugarcane and pine. The main objective of this study is to evaluate the assessment methods used for calculating the impacts of biofuel production and this has been carried out with the help of five methods: net energy analysis, life cycle assessment, cumulative exergy analysis, consumptive water analysis, and emergy synthesis. Detailed data acquisition was carried out to obtain primary input data required for the four feedstocks. This data with some secondary data from literature was used to calculate the impacts using five assessment methods. A sensitivity analysis was also performed to evaluate the stability of the five assessment methods. Three scenarios were considered viz., change in biomass yield, change in transportation distance and change in ethanol yield. It was found that emergy synthesis and life cycle assessment are relatively less sensitive to changes in input than cumulative exergy and net energy analysis methods. Finally the five methods were compared and the advantages and limitations of each have been discussed. Two case studies to demonstrate combining two or more methods have also been presented.
