ABSTRACT:
A carbon monoxide shift process at a pressure of at least 15 atm. abs. is carried out over an oxidic and/or sulphidic catalyst of a specified level of activity in a 2-zone bed. The upstream zone has an outlet temperature in the range 350.degree.-400.degree. C. and the downstream zone has a higher outlet temperature, for example up to 550.degree. C. The catalyst in the upstream zone differs from the catalyst in the downstream zone by containing more catalytic material per unit volume and/or by having a lower area/volume ratio and/or by having a lower porosity.
