Abstract
A method for decomposing halogenated organic compounds which comprises: (a) heating the halogenated organic compound to a temperature above about 300.degree. C. and (b) contacting the heated organic compound with a catalytic amount of ruthenium-platinum catalyst in the presence of an oxidizing agent at a temperature of at least about 350.degree. C.
Claims16
A method for decomposing chlorinated organic compounds, said chlorinated orgainc compounds containing 1 to 4 carbon atoms and containing at least as many hydrogen atoms as chlorine atoms, said method comprising:
- a. heating the chlorinated organic compounds to a temperature above about 300.degree. C., and
- b. then contacting the heated organic compound with a catalytic amount of ruthenium-platinum catalyst in the presence of an oxidizing agent, selected from the group consisting of air, oxygen, and mixtures of nitrogen and oxygen, at a temperature of at least about 350.degree. C., said catalysts being present in the range of 1 to 20 parts of platinum per part of ruthenium.
A method for substantially reducing the amount of chlorinated organic compounds in a gaseous stream containing chlorinated organic compounds by decomposing said chlorinated organic compounds, said chlorinated organic compounds containing 1 to 4 carbon atoms and containing at least as many hydrogen atoms as chlorine atoms, said method comprising:
- a. heating a gaseous stream comprising said chlorinated organic compounds and an oxidizing gas selected from air and a mixture of nitrogen and oxygen to a temperature above about 300.degree. C., and
- b. then passing the heated gaseous stream of step (a) through a heated zone having a temperature of at least about 350.degree. C. wherein it contacts a catalytic amount of a ruthenium-platinum catalyst said catalysts being present, based on the noble metal content thereof, in the range of 1 to 20 parts of platinum per part of ruthenium.
