WATER-GAS SHIFT CATALYST

摘要

A catalyst precursor for preparing a catalyst suitable for use in a sour water-gas shift process is described, including; 5 to 30% by weight of a catalytically active metal oxide selected from tungsten oxide and molybdenum oxide; 1 to 10% by weight of a promoter metal oxide selected from cobalt oxide and nickel oxide; and 1 to 15% by weight of an oxide of an alkali metal selected from sodium, potassium and caesium; supported on a titania catalyst support.
