Abstract
A catalyst and process for treating gas streams which contain halogenated organic compounds, non-halogenated organic compounds, carbon monoxide or mixtures thereof, and particularly gas streams which contain organobromides. The catalyst comprises at least one platinum group metal, zirconium oxide and at least one oxide of manganese, cerium or cobalt.
Claims28
A catalyst for treating a gas stream which contains compounds selected from the group consisting of halogenated organic compounds, non-halogenated organic compounds, carbon monoxide and mixtures thereof, said catalyst comprising at least one platinum group metal, zirconium oxide and manganese oxide in an amount of at least about 10 weight percent (as Mn.sub.2 O.sub.3, and wherein the catalyst is substantially free of vanadium.
A catalyst for treating a gas stream which contains compounds selected from the group consisting of halogenated organic compounds, non-halogenated organic compounds, carbon monoxide and mixtures thereof, said catalyst comprising i) a core material consisting essentially of zirconium oxide and manganese oxide in an amount of at least about 10 weight percent;
- and ii) at least one platinum group metal dispersed on said core material in an amount from about 0.01 to about 8 weight percent, based on the total weight of the catalyst, wherein the catalyst is substantially free of vanadium.
