ABSTRACT:
In producing methanol by the reaction of carbon monoxide and hydrogen, a starting gas deficient in hydrogen, e.g. as produced by coal gasification, is mixed with a hydrogen rich gas and fed to a synthesis loop where it is mixed with unreacted gas from the synthesis stage. A part stream of gas is taken from the loop. Either that part stream, or the gas in the loop prior to synthesis, is subjected to the catalytic shift reaction with steam. Carbon dioxide is removed from the gas taken from the loop to form the hydrogen rich stream.
