WATER GAS SHIFT PROCESS

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° C. over a water-gas shift catalyst to form a hydrogen-enriched...

Beschreibung
Zusammenfassung:	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° 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.
