	Gasification - Wikipedia, the free encyclopedia
		Gasification is a process that converts carbonaceous materials, such as coal, petroleum, petroleum coke or biomass, into carbon monoxide and hydrogen.
		The gasification process was originally developed in the 1800s to produce town gas for lighting and cooking.
		It is now recognized that gasification has wider applications; in particular the production of electricity using Integrated Gasification Combined Cycles (IGCC), with the long-term aim of producing hydrogen for fuel cells.

	EPA: Federal Register: Regulation of Hazardous Oil-Bearing Secondary Materials From the Petroleum Refining Industry and ... (Site not responding. Last check: 2007-11-03)
		Proponents of gasification technologies likewise maintain that petroleum refineries would be more likely to recycle their solid waste if the regulatory status of the devices and the gasification system were clearly identified to be a part of the fuel manufacturing process.
		Gasification of hazardous oil-bearing secondary materials from petroleum refineries involves the recovery of organic components from the residuals of crude oil refining to produce a gaseous fuel, which can be viewed as part of a fuel production process.
		Gasification systems can be designed to operate at high or low pressures, reducing conditions, using dry or wet feed systems, but they are all operated in a manner that limits the complete oxidation of hydrogen and carbon monoxide to water and carbon dioxide.

	IGCC
		Gasification technology has been in use for over 100 years from the "town gas" operations in the late 19th and early 20th centuries.
		By the late 1980s, gasification technology was then integrated with a combined cycle power plant to produce a high efficiency low-emission coal fueled power plant.
		The term "gasification" refers to the process of converting carbon based feedstocks to synthetic gas, called "syngas." Gasification can use a wide range of fuels including coal, petroleum coke, biomass, oil refinery bottoms (waste oil), digester sludge, and virtually anything that contains carbon and can be fed into a gasification chamber.

	Gasification and pyrolysis of biomass (summary)
		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.
		With pressurised gasification higher overall electrical efficiencies can be achieved, but greater technical and financial resources are required to feed the biomass into the gasifier, and problems with gas cleaning may occur.
		At present, biomass gasification is starting from an even less favourable economical position than energy use of biomass through combustion, as the technically attractive gasification systems are in an earlier phase of development and demonstration.

	What is Gasification? (Site not responding. Last check: 2007-11-03)
		The gasification process converts any carbon-containing material into a synthesis gas composed primarily of carbon monoxide and hydrogen, which can be used as a fuel to generate electricity or steam or used as a basic chemical building block for a large number of uses in the petrochemical and refining industries.
		Gasification adds value to low- or negative-value feedstocks by converting them to marketable fuels and products.
		Typical raw materials used in gasification are coal, petroleum based materials (crude oil, high sulfur fuel oil, petroleum coke, and other refinery residuals), gases, or materials that would otherwise be disposed of as waste.

	What is Gasification? (Site not responding. Last check: 2007-11-03)
		Gasification is a thermal process that converts solid fuel into an fuel gas mixture of medium to low heating value.
		Indirect gasification is accomplished using steam as an oxidant.
		Steam gasification is thermodynamically more efficient than direct gasification, but practical heat transfer limitations and thermodynamic availability requirements for high temperature heat exchange often makes reality a bit different.

	Electricity from wood waste
		Heat was applied to the fuel either internally or externally to initiate a self-sustaining gasification of the fuel in an oxygen deprived environment.
		Wood-gas modified vehicles were therefore technically a "dual fuel" vehicle in that a self-sustaining gasification of the wood charcoal, or coal required another fuel to start the process.
		Both these varieties of biomass were found to be quite suitable for gasification, i.e., a process by which the biomass is converted into producer gas through partial combustion in the presence of controlled supply of oxygen.

	Troubled Times: Coal Gasification
		Coal gasification is a process for converting coal partially or completely to combustible gases.
		From the early 19th century until the 1940s almost all fuel gas distributed for residential or commercial use in the United States was produced by the gasification of coal or coke.
		The simplest method, and the first used, was to heat coal in a retort in the absence of air, partially converting coal to gas with a residue of coke; the Scottish engineer William Murdock used this technique in pioneering the commercial gasification of coal in 1792.
