Patent ID: 7435394

Claim:
An apparatus for treating a perfluorocompound comprising a means for obtaining a gas flow by diluting a perfluorocompound with nitrogen or air; a means for adding steam to said gas flow; a reactor for bringing said gas flow containing the added steam into contact with a catalyst to decompose the perfluorocompound; a heating means for heating said catalyst comprising Ni, Al and W as catalytically active ingredients and comprising a composite oxide of Ni and Al and a composite oxide of Ni and W which has been packed in said reactor, to the decomposition temperature of the perfluorocompound; an exhaust gas washing tank for bringing a gas containing decomposition products produced in said reactor into contact with water or an alkali to remove hydrogen fluoride from the gas, wherein a mole number of W is less than a mole number of Ni, and the mole number of Ni is less than a mole number of Al; and said catalyst contains W in a proportion of 1 to 5 wt % based on a total weight of said catalyst comprising a composite oxide of Ni and Al.
