World gasification capacity is expected to grow by more than 70% by 2015. While gasification is not a new process, the higher price in crude has lead operators and refineries to look at all possible coal-based technologies for energy conversion, and with the flow of heavy oil, tar sands and other unconventional feedstocks making their way to the refineries for processing, refinery managers and engineers alike must be made aware of how to process these uncommon energy sources. Gasification of Unconventional Feedstocks addresses these unfamiliar feeds and provides a quick and up-to-date reference on the background, process technology and downstream applications required to help refineries maximize profits turning low-value feedstock to beneficial syngas and other fuel products. Clear and comprehensive, Gasification of Unconventional Feedstocks provides engineers and refinery managers with the tools needed to quickly adapt to the more unconventional feedstocks and still maximize their refineries potential. Get up to speed on how to adjust your refinery's processing to unconventional feedstocks Understand the technology necessary to safely and effectively manage unfamiliar feeds Turn low-value product to profit quickly with must-have tips and rules of thumb

Most coveted energy forms nowadays are gas in nature and electricity due to their environmental cleanness and convenience. Recently, gasification market trend is starting to switch to low-grade feedstock such as biomass, wastes, and low-rank coal that are still not properly utilized. In this sense, the most promising area of development in gasification field lies in low-grade feedstock that should be converted to more user-friendly gas or electricity form in utilization. This book tried to shed light on the works on gasification from many parts of the world and thus can feel the technology status and the areas of interest regarding gasification for low-grade feedstock.

Five economically advantaged biomass feedstocks identified in the US Department of Energy's 2016 Billion Ton Study were gasified and the syngas reformed at the bench scale to study the feedstock price-performance relationship. The distribution of reformed syngas compositions, heating values, and yields were similar across the different feedstocks and blends thereof, which ranged from inexpensive residual wastes to more expensive and higher quality biomass, revealing that feedstock performance was mostly insensitive to its price. Custom blended feedstocks produced syngas with characteristics resembling linear combinations of syngas from single-component feedstocks, supporting the ability to customize and predict blended properties based on single-feedstock data. A techno-economic analysis of specific feedstock costs for producing high-octane gasoline showed that miscanthus and forest residues were the most cost-effective with gas yields consistent with experimental gasification data. A field-to-wheels life-cycle assessment of greenhouse gas emissions showed that forest residues was the most environmentally benign feedstock of those studied.

With the need for developing a more sustainable world, there is a desire to shift from fossil fuels to biofuels, produced using the concept of biorefineries. Within the last few decades, thermochemical conversion technologies have gained a great deal of attention for producing advanced biofuels. In this context, this chapter elaborates different aspects of biomass gasification technology, as a representative of thermochemical pathways, and suggested potential solutions to enhance the efficacy of the process. To fulfill this goal, different types of biomass feedstock are employed to examine the potential of each in bioenergy production through gasification process. The chapter is consisting of a series of dependent studies to investigate the path for advancements in the gasification process. The first study investigates the parametric effect of experimental conditions during gasification of individual biomass feedstocks to select the best biomass feedstock for next study. It is also demonstrated that how the variation in the syngas composition interacts with H2/CO ratio. The other study investigates the potential of composite feedstocks based on the results from the first study. The last study investigates the potential failure scenarios and the likelihood of their occurrence are explored.

As a follow-up to the Handbook of Gasification Technology, also from Wiley-Scrivener, Synthesis Gas goes into more depth on how the products from this important technology can reduce our global carbon footprint and lead the United States, and other countries, toward energy independence. The environmental benefits are very high, and, along with carbon capture and renewable fuels, synthesis gas (or syngas) is a huge step toward environmental sustainability. Synthesis gas is one of the most important advancements that has ever occurred in energy production. Using this technology, for example, coal, biomass, waste products, or a combination of two or more of these can be gasified into a product that has roughly half the carbon footprint of coal alone. Used on a massive scale, just think of the potential for reducing carbon emissions! Synthesis Gas covers all aspects of the technology, from the chemistry, processes, and production, to the products, feedstocks, and even safety in the plant. Whether a veteran engineer or scientist using it as a reference or a professor using it as a textbook, this outstanding new volume is a must-have for any library.

Gasification provides an excellent overview of current technologies for the gasification of coal, oil, gas, biomass and waste feed stocks. Starting from the basic theory, it reviews the potential feed stocks and their suitability for different types of gasification process. Commercial and near-commercial processes are described individually and various features discussed in detail. There is a comprehensive review of contaminants in synthesis gas as well as of gas treating processes. Gasification, the key technology enabling the production of biofuels from all viable sources--some examples being sugar cane and switch grass. This versatile resource not only explains the basic principles of energy conversion systems, but also provides valuable insight into the design of biomass gasifiers. The author provides many worked out design problems, step-by-step design procedures and real data on commercially operating systems. After fossil fuels, biomass is the most widely used fuel in the world. Biomass resources show a considerable potential in the long term if residues are properly handled and dedicated energy crops are grown.
