Abstract
A catalyst is disclosed for treating gas streams containing organic compounds such as halogenated organic compounds. The catalyst is comprised of vanadium oxide, zirconium oxide and at least one oxide of manganese, cerium or cobalt. Also disclosed is a process for treating gas streams using such catalysts.
Claims26
A catalyst for treating a gas stream containing compounds selected from the group consisting of halogenated organic compounds, other organic compounds and mixtures thereof, said catalyst comprising from about 40 up to about 88 weight percent of zirconium oxide and (i) vanadium oxide and (ii) at least one oxide selected from the group consisting of manganese oxide, cerium oxide and cobalt oxide.
A catalyst for treating a gas stream containing compounds selected from the group consisting of halogenated organic compounds, other organic compounds and mixtures thereof, said catalyst comprising i) a core material consisting essentially of zirconium oxide and manganese oxide;
- and ii) vanadium oxide dispersed on said core material in an amount from about 0.1 weight percent up to about 20 weight percent (as V.sub.2 O.sub.5) of the catalyst.
A process for treating a gas stream containing compounds selected from the group consisting of halogenated organic compounds, other organic compounds and mixtures thereof, comprising contacting said gas stream at a temperature of from about 175.degree. C. up to about 550.degree. C. with a catalyst comprising from about 40 up to about 8 weight percent of zirconium oxide and (i) vanadium oxide and (ii) at least one oxide selected from the group consisting of manganese oxide, cerium oxide and cobalt oxide in the presence of an effective amount of oxygen and water.
A process for treating a gas stream containing compounds selected from the group consisting of halogenated organic compounds, other organic compounds and mixtures thereof, comprising contacting said gas stream at a temperature of from about 175.degree. C. up to about 550.degree. C. with a catalyst comprising i) a core material consisting essentially of zirconium oxide and manganese oxide;
- and ii) vanadium oxide dispersed on said core material in an amount from about 0.1 weight percent up to about 20 weight percent (as V.sub.2 O.sub.5) of the catalyst.
