Book excerpt: Abstract: In the US, the main source for ethanol production is corn grain fermented to ethanol by the dry-mill (DG) process. Corn has high starch content and is the largest crop produced in the US making it the most suitable source for ethanol production. However, during this process, as much as 6% of the starch in the corn grain is not converted and remains in the dry distiller's grains with solubles (DDGS). In addition, cellulose present in the grain, another potential supply of glucose for fermentation to ethanol, is also not converted during this process. Hydrodynamic cavitation is a phenomenon that releases energy due to the collapse of cavities formed inside a liquid flow. In this study, this phenomenon is used as a pretreatment along with cellulase addition to improve the yield of ethanol by releasing and hydrolyzing the unconverted carbohydrate fractions. A hydrodynamic cavitation unit was installed at a 100-gallon pilot plant and at a 100 million gallon dry mill ethanol plant. During pilot scale experiments four and three different cavitation pressures in a range from 50psi to 350psi were evaluated on starch release after liquefaction and on ethanol production after simultaneous saccharification and fermentation (SSF). The effects of the cavitation and a jet cooker treatment on ethanol production after SSF were also compared. At commercial scale cavitation and cellulase addition during liquefaction and SSF was tested to determine its impact on glucose and ethanol production. Three different experiments were conducted and the effects of hydrodynamic cavitation were assessed on liquefaction parameters. The effects of hydrodynamic cavitation and cellulase addition on SSF parameters and ethanol production were determined. During pilot scale three effect-levels was identified according to the results on ethanol production: 1) Minimum, pressures showing no significant difference as compared to control pressure; 2) Optimum, pressures showing significant differences as compared to the control but not with the maximum; 3) Maximum, pressure with the best ethanol production within the pressure range tested in this study. Results showed an increase of 11.6% in total glucose released after liquefaction and 2.7% in the ethanol production after SSF with the maximum tested level of cavitation, while traditional jet cooking systems reduced ethanol production by 0.4% as compared to controls. Commercial scale tests at the optimum caviation pressure demonstrated that cavitation affected the liquefaction parameters and led to significant increases on ethanol production and solids conversion after SSF. Ethanol production increased by 2.2% in cavitated samples as compared to uncavitated samples. Cellulase also affected uncavitated and cavitated samples, increase in ethanol production was around 2.5% for uncavitated and 4.3% for cavitated. The electrical energy used for cavitation during commercial scale ethanol production was 1/16th of that contained in the additional ethanol produced and the value of the ethanol created was more than thirty times the cost of the electricity used to produce it. In summary, hydrodynamic cavitation can be used to increase ethanol production at pilot and commercial scales improving the productivity, profitability and net energy value (NEV) of DG ethanol plants.

Book excerpt: Biofuels production is one of the most extensively studied fields in the energy sector that can provide an alternative energy source and bring the energy industry closer to sustainability. Biomass-based fuel production, or renewable fuels, are becoming increasingly important as a potential solution for man-made climate change, depleted oil reserves, and the dangers involved with hydraulic fracturing (or "fracking"). The price of oil will always be volatile and changeable, and, so long as industry and private citizens around the world need energy, there will be a need for alternative energy sources. The area known as "biofuels and biofeedstocks" is one of the most important and quickly growing pieces of the "energy pie." Biofuels and biofeedstocks are constantly changing, and new processes are constantly being created, changed, and improved upon. The area is rapidly changing and always innovative. It is important, therefore, that books like the volumes in this series are published and the information widely disseminated to keep the industry informed of the state-of-the-art. This third volume in the Advances in Biofeedstocks and Biofuels series focuses on the production of liquid biofuel, covering all of the major biofuels, such as biodiesel, biobutanol, bioethanol, and others. This engaging text touches on all of the most important new processes and technologies, providing the most up-to-date coverage of the science available to industry. It is a must-have for any engineer or scientist working with biofuel technology.

A total of oral presentations (including Special Topic presentations) and 329 poster presentations were delivered. The high number of poster submissions required splitting the poster session into two evening sessions. (Conference details are posted at http://www.eere.energy.gov/biomass/biotech_symposium/.) Almost 35% of the attendees were international, showing the strong and building worldwide interest in this area. Nations represented included Australia, Austria, Belgium, Brazil, Canada, Central African Republic, China, Denmark, Finland, France, Gambia, Germany, Hungary, India, Indonesia, Italy, Japan, Mexico, The Netherlands, New Zealand, Portugal, South Africa, South Korea, Spain, Sweden, Thailand, Turkey, United Ki- dom, and Venezuela, as well as the United States. One of the focus areas for bioconversion of renewable resources into fuels is conversion of lignocellulose into sugars and the conversion of s- ars into fuels and other products. This focus is continuing to expand toward the more encompassing concept of the integrated multiproduct biorefinery--where the production of multiple fuel, chemical, and energy products occurs at one site using a combination of biochemical and ther- chemical conversion technologies. The biorefinery concept continues to grow as a unifying framework and vision, and the biorefinery theme f- tured prominently in many talks and presentations. However, another emerging theme was the importance of examining and optimizing the entire biorefining process rather than just its bioconversion-related elements.

This book was released on 2002-08-31 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomethanization of the Organic Fraction of Municipal Solid Wastes is a comprehensive introduction to both the fundamentals and the more practical aspects of the anaerobic digestion of organic solid wastes, particularly those derived from households, that is, the organic fraction of municipal solid wastes (OFMSW). It can be used as a textbook for specialized courses and also as a guide for practitioners. In the first part, the book covers the relevant aspects of anaerobic digestion (AD) of organic wastes. The fundamentals and kinetic aspects of AD are reviewed with particular emphasis on the aspects related to solid wastes. This introduction is necessary to have a comprehensive view of the AD process and to understand the practical principles as well as the origin of possible problems arising from the management of the process. Chapter 2 emphasizes the role of kinetics in designing the reactor, paying special attention to existing models, particularly the dynamic ones. Through this introduction, it is intended to facilitate the technology transfer from laboratory or pilot plant experiences to full-scale process, in order to implement improvements in current digesters. Laboratory methods are described for the analysis and optimization of reactor performance, such as methanogenic activity tests or experimental evaluation of the biodegradation kinetics of solid organic waste. The different reaction patterns applied to industrial reactors are outlined. Industrial reactors are classified in accordance with the system they use, pointing out advantages and limitations. Co-digestion, enabling the co-treatment of organic wastes of different origin in a more economically feasible way, is described in detail. Examples of co-digestion are given, with OFMSW as a base-substrate. Finally, full-scale co-digestion plants are discussed. Various types (mechanical, biological, physico-chemical) of pre-treatment to increase the biodegradability, and thus the yields of the process, are reviewed in detail. The use of the fermentation products of anaerobic digesters for biological nutrient removal processes in wastewater treatment plants is described. This constitutes an example of integrated waste management, a field in which both economic and technical advances can be achieved. Balances are given to justify the approach, and a full-scale case study is presented. The important topic of economics and the ecological advantages of the process are emphasized. The use of compost, the integration with composting technology, and advantages over other technologies are detailed in the framework of an environmental impact assessment of biowaste treatment. Finally, the anaerobic digestion of MSW in landfills is reviewed in detail, with emphasis on landfill process enhancement and strategies for its application.
