Underground coal gasification (UCG) is a method of converting unworked coal coal still in the ground into a combustible gas. UCG technology allows countries that are endowed with coal to fully utilise their resource from otherwise unrecoverable coal deposits. UCG uses a similar process to surface gasification.

Patent: Coal or coke gasification. [Process for reducing losses of combustibles in gasification of coal with steam and O in fluidized bed; process carried out at 1025 atm]
The process can costeffectively remove more than 95 percent of the mercury in coal, and more than 99 percent of the sulfur can be recovered and marketed for use primarily in the fertilizer industry. Additionally, the gasification process produces no ash and recycles byproducts into useful products, including road construction materials.

Since the first coal gasifier using the Air Products Gasification Process began operating nearly 40 years ago, there are now more than 100 Air Products Gasification Process reactors operating or in the planning stages around the world. Over 100 coal types have been successfully processed, including blends of highash coal and petcoke.
coal mill in coke gasification process. Coal gasification Wikipedia. Coal gasification is the process of producing syngas–a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), methane (CH 4), and water vapour (H 2 O)–from coal .
In this paper, a novel highefficiency coal gasification technology is proposed in which a regenerative unit is applied to recover syngas sensible heat to generate steam; then, the hightemperature steam is used to gasify coke from a pyrolyzer.
This plant uses petroleum coke or coal coke to produce synthetic gas, which can be raw material for the manufacturing of many chemicals such as ammonia, methanol, hydrogen cyanide, etc., and fuel for electrical power plants. This complete plant includes coke handling system, gasification reactors, syngas scrubber and purification system, as well as slag treatment system.

the RENUGAS® technology for gasification of highly reactive fuels such as peat, biomass, pulp mill residues and wastes. Through this development process it was determined that a single gasifier design could be used for all of these fuels, including mixtures such as biomass and coal. GTI''s gasification process is an excellent
Petroleum coke gasification: A review. ... The influences of coal slurry concentration and O 2/coal ratio on the gasification process are investigated. Under the condition of feeding carbon being ...
Coal utilization Coal utilization Gasification: While the goal of combustion is to produce the maximum amount of heat possible by oxidizing all the combustible material, the goal of gasification is to convert most of the combustible solids into combustible gases such as carbon monoxide, hydrogen, and methane. During gasification, coal initially undergoes devolatilization, and the residual ...
Coal gasification is a process whereby a hydrocarbon feedstock (coal) is converted into gaseous components by applying heat under pressure in the presence of steam. Rather than burning, most of the carboncontaining feedstock is broken apart by chemical reactions that produce "syngas." Syngas is primarily hydrogen and carbon monoxide, but the exact composition can vary.
Apr 05, 2013· Coal Gasification processes. Various coal gasification processes are based on fixed bed ( Lurgi), Fluidized bed (Winkler) and Entrained bed (Shell and Texaco). The characteristics of these processes are compared in Tab 1. The most popular Fixed bed dry bottom type process has been described in detail.
Coal Gasification. Coal gasification is a wellproven technology that began with the production of coal gas for towns and progressed to the production of fuels, such as oil and synthetic natural gas (SNG), chemicals, and more recently, to largescale integrated gasification combined cycle .
