Coal gasification is a process in which coal is converted to a lowgrade gas; it can be regarded in many ways as fuelrich combustion. Oxygenblown coal gasifiers operate at overall equivalence ratios (fuel to oxidizer ratio normalized by fuel to oxidizer ratio required to fully oxidize fuel) greater than two. Commercial or nearcommercial ...

The process involves pumping oxygen and steam through a small borehole into the coal seam to produce a small and controlled combustion. Unlike coalbed methane, therefore, the actual coal is converted from a solid state into gas. The hydrogen, methane, carbon monoxide and CO2 are then siphoned off through a second borehole.

Exxon process. In the 1970 s, Exxon company [6], [7], [8] developed a continuous and stable 1 t/d process development unit (PDU) (inner diameter m and height 25 m), as shown in Fig. 1, in which the coal is gasified at 973 K and MPa with 8 wt% KOH and K 2 CO 3 as the catalysts and superheated steam (1073 K) as the gasification agent, respectively.
The GE gasification units will be installed at a coal chemical plant in Yulin, Shaanxi Province. Once the project is completed, the facility is expected to process enough coal to produce approximately 25 million normal cubic meters of syngas per day, which will be used to make approximately million tons of methanol per year making it the ...

Underground coal gasification (UCG) is an industrial process which converts coal into product gas. UCG is an insitu gasification process, carried out in nonmined coal seams using injection of oxidants and steam. The product gas is brought to the surface through production wells drilled from the surface. The predominant product gases are methane, hydrogen, carbon monoxide and carbon dioxide.
