ABSTRACT:
Catalyst for use in the high temperature shift reaction comprising in its active form a mixture of zinc alumina spinel and zinc oxide in combination with an alkali metal selected from the group consisting of Na, K, Rb, Cs and mixtures thereof. The catalyst has a Zn/Al molar ratio in the range 0.5 to 1.0 and a content of alkali metal in the range 0.4 to 8.0 wt % based on the weight of oxidized catalyst.
