1. A catalyst material comprising:
a carrier material; and a catalytically-active molybdenum compound, a catalytically-active tungsten compound, or a combination thereof, disposed on the carrier material, present in the range of about 1 weight % to about 10 weight % based on the total weight of the catalyst material; wherein any additional catalytically-active metal compounds that are present are present in a total amount less than about 1 weight % based on the total weight of the catalyst material; wherein the amount of any catalytically-active molybdenum compound is calculated as MoO3, wherein the amount of any catalytically-active tungsten compound is calculated as WO3, and wherein the amounts of any additional catalytically-active metal compounds are calculated as oxide; wherein “catalytically-active” refers to catalytic activity in the sour gas shift reaction; and wherein the catalyst material is in sulfided form.
