A process is described for increasing the hydrogen content of a synthesis gas mixture comprising hydrogen, carbon oxides and steam, comprising the steps of: passing the synthesis gas mixture at an inlet temperature in the range 170-500&#xb0; C. over a water-gas shift catalyst to form a hydrogen-enriched shifted gas mixture, wherein the water-gas shift catalyst is in the form of a cylindrical pellet having a length C and diameter D, wherein the surface of the cylindrical pellet has two or more flutes running along its length, said cylinder having no through-holes and domed ends of lengths A and B such that (A+B+C)/D is in the range 0.25 to 0.25, and (A+B)/C is in the range 0.03 to 0.30.

Water gas shift process

A catalyst precursor, suitable for use after reduction as a water-gas shift catalyst, is described, which is in the form of a pellet comprising one or more oxides of iron, wherein the catalyst precursor has a pore volume 0.30 cm/g and an average pore size in the range 60 to 140 nm The precursor may be prepared by calcination of precipitated iron compounds at temperatures in the range 400-700&#xb0; C.
