Methanol from coal An adaption from the past

1979-11-1  Coal from the mine is crushed and dried to 8% moisture, then sent to a fluidized bed gasifier which produces H2, CO, CO2, methane and inert material from subbituminous coal. The hot gas is treated to ensure the proper H2 to CO ratio and remove sulfur and excess CO2, and is compressed in a methanol synthesis loop in order to produce a total of 7050 tons/day of methanol and 35 liquid

Production of Coal Bed Methane in Germany

Methane, the major component of mine gas, is a 20 times more potent greenhouse gas than CO 2. Extraction of gas from coal seams for power generation and heat supply thus reduces the emissions significantly. Abandoned Mine Methane (AMM) and Coal Mine Methane (CMM) projects are now prevalent in several sites in North Rhine-Westphalia and Saarland.
