Abstract
Methanol is synthesised in a synthesis loop wherein recycled unreacted gas, optionally together with part of the make-up gas, is passed through a bed of synthesis catalyst under methanol synthesis conditions, make-up gas is then added and the mixture passed through at least one further bed of synthesis catalyst under methanol synthesis conditions prior to separation of the synthesised methanol. Preferably the further bed of synthesis catalyst is located in a heat exchange reactor producing pressurised hot water which is employed to saturate a hydrocarbon feedstock from which the make-up gas is produced by steam reforming.
