Coal Gasification and Its Applications $148.16 Skyrocketing energy costs have spurred renewed interest in coal gasification. Currently available information on this subject needs to be updated, however, and focused on specific coals and end products. For example, carbon capture and sequestration, previously given little attention, now has a prominent role in coal conversion processes. This book approaches coal gasification and related technologies from a process engineering point of view, with topics chosen to aid the process engineer who is interested in a complete, coal-to-products system. It provides a perspective for engineers and scientists who analyze and improve components of coal conversion processes. The first topic describes the nature and availability of coal. Next, the fundamentals of gasification are described, followed by a description of gasification technologies and gas cleaning processes. The conversion of syngas to electricity, fuels and chemicals is then discussed. Finally, process economics are covered. Emphasis is given to the selection of gasification technology based on the type of coal fed to the gasifier and desired end product: E.g., lower temperature gasifiers produce substantial quantities of methane, which is undesirable in an ammonia synthesis feed. This book also reviews gasification kinetics which is informed by recent papers and process design studies by the US Department of Energy and other groups, and also largely ignored by other gasification books. - Approaches coal gasification and related technologies from a process engineering point of view, providing a perspective for engineers and scientists who analyze and improve components of coal conversion processes - Describes the fundamentals of gasification, gasification technologies, and gas cleaning processes - Emphasizes the importance of the coal types fed to the gasifier and desired end products - Covers gasification kinetics, which was largely ignored by other gasification books Provides a perspective for engineers and scientists who analyze and improve components of the coal conversion processes Describes the fundamentals of gasification, gasification technologies, and gas cleaning processes Covers gasification kinetics, which was largely ignored by other gasification books

Combustion and Gasification in Fluidized Beds $179.5 Besides being one of the best Clean Coal Technologies, fluidized beds are also proving to be the most practical option for biomass conversion. Although the technology is well established, the field lacks a comprehensive guide to the design and operating principles of fluidized bed boilers and gasifiers. With more than 30 years of research and industrial experience, Prabir Basu answers this pressing need with Combustion and Gasification in Fluidized Beds. This book is a versatile resource that explains how fluidized bed equipment works and how to use the basic principles of thermodynamics and fluid mechanics in design while providing insight into planning new projects, troubleshooting existing equipment, and appreciating the capabilities and limitations of the process. From hydrodynamics to construction and maintenance, the author covers all of the essential information needed to understand, design, operate, and maintain a complete fluidized bed system. It is a must for clean coal technology as well as for biomass power generation. Beginning with a general introduction to fossil or biofuel conversion choices, the book surveys hydrodynamics, fundamentals of gasification, combustion of solid fuels, pollution aspects including climate change mitigation, heat transfer in fluidized beds, the design and operation of bubbling and circulating fluidized bed boilers, and various supporting components such as distributor grates, feeding systems, and gas-solid separators.

Energy from Biomass: A Review of Combustion and Gasification Technologies $24.95 While energy is essential for development, standard fossil fuels are often in short supply in countries where it is needed most. However, alternative fuel resources abound in the form of agricultural and municipal waste or "biomass." This report reviews the state of the art of biomass combustion and gassification systems, their advantages and disadvantages. It also encourages investment in use of these technologies to enable developing countries to better exploit their biomass resources and help close the gap between their energy needs and their energy supply.

Fundamental Issues in Control of Carbon Gasification Reactivity (Nato Science Series E: (closed)) $378.84 There are two basic issues in controlling the reactivity of carbon: (i) reduction of the gasification rate of carbon materials in hostile environments, and (ii) increasing the gasification rate in order to utilize carbonaceous compounds more effectively. Although these two objectives appear somewhat contradictory, they are both necessary to a general understanding of the gasification reactivity of...

Gasification Of Biomas From Wood Pellets To Algae

Gasification of biomass, which is a renewable and sustainable energy source, is a promising alternative to using fossil fuel based fuels, at high and extremely variable cost. Energy sources will come from an increasing list of biomass resources - sources of energy which have gone largely ignored and unused for more than 50 years. The list is likely to be so wide that even algae are likely to be produced to meet the demand for cheap and sustainabl grenn energy in the future.

Combining the application of biomass gasification - where a mixture of mainly hydrogen and carbon monoxide is generated - with fuel cells - where the hydrogen is electrochemically converted into electricity - offers a highly efficient and incredibly flexible energy source. Gasification systems basically consists of a gasifier unit, purification system and energy converters - burner or engine.

Wood Pellet Gasification

In one not atypical gasification system fuel, initially wood pellets, is supplied from an indoor wood pellet storage site into the gasification plant. The fuel is fed through lock hopper systems by feeding screws into the lower section of the gasifier's fluidized bed.

Fuels which can be used without difficulty include ground seed corn, switchgrass, cornstover, RDF (refused derived waste - subject to licensing constraints), woodchips, and sawdust to name just a few. The gasifier is a fluidized bed gasifier meaning that a tube of sand (the bed) is mixed (fluidized) by passing air through holes in the bottom plate of the tube.

Producer gas is created in the gasifier and this isa fuel gas and chemcial source which can be used to replace fossil fuels in a wide range of devices, including road and rail transport.

Other devices which could be retrofitted with gasifiers are furnaces for melting non-ferrous metals and for heat treatment, tea dryers, ceramic kilns, boilers for process steam and thermal fluid heaters. Producer gas can also commonly be used for commercial cooking applications.

Gasification of wood and wood-type residues and waste in fixed bed or fluidised bed gasifiers with subsequent burning of the gas for heat production is state of the art in Northern Europe. However, the market has hardly yet been expoited aven in those countries where the wood gasifiers which are employed in the Scandinavian countries are used almost almost entirely just for heat generation.

Biomass is a sustainable energy resource which is destined to play an important role in future energy production and as an organic chemical raw material supply source, with biomass gasification the most promising conversion technology and very effective in reducing greenhouse gas emissions.

Biomass is converted into a gaseous mixture of hydrogen, carbon monoxide, carbon dioxide, and other compounds by applying heat under pressure in the presence of steam and a controlled amount of oxygen (in a unit called a gasifier). The biomass is broken apart chemically by the gasifier's heat, steam, and oxygen, setting into motion chemical reactions that produce a synthesis gas, or "syngas"-a mixture of primarily hydrogen, carbon monoxide, and carbon dioxide. It is this synthesis gas which can then be further reacted and refined to replace oil as a raw material for use in refineries.

Finally, we said that we would be telling you about the, improbable as it may seem, use of algae as a biomass energy source.

Algae Energy Farms

Algae energy farms which might be light enough to be integrated into large, flat rooftops and could therefore be present even right in the centre of our cities could be manufacturing green energy from the sun on a daily basis. If factory and commercial buildings could support the carbon recycling systems on-site, the waste heat and other byproducts of the carbonizer and fuel cell could be used for industrial process heat or space heat. In addition algae has been a hot topic lately as a possible solution to most of our fuel and food needs. Nearly half of an alga's mass is made up of lipids (a major component of vegetable oil) that can be used in the production of biofuels, and all sorts of plastic and the chemicals now made from oil.

So, if someone you know suggests that you should consider using gasification in some way, don't just laugh and dismiss him as a crank. He just could be right!
