Abstract
A process for producing methanol wherein coal is gasified by a treatment with water vapor and oxygen at elevated temperature, the resulting gas is cooled and is scrubbed with an organic solvent to remove impurities from the gas, the carbon oxides contained in the gas are catalytically reacted with hydrogen to form methanol, and the methanol is separated, the improvement comprises subjecting the residual gas left after the separation of the methanol to a catalytic cracking treatment with water vapor under pressure and at elevated temperature to form hydrogen and carbon oxides and cooling the cracked gas and recycling it to the methanol synthesis.
