ABSTRACT:
A combustion catalyst for removing organic compounds which includes a mixture of a zeolite and a metal oxide containing at least one of the elements of the platinum group. Another combustion catalyst for removing organic compounds which comprises an alumina having such a pore size distribution that, where “a” represents a pore radius in Å at the maximum of the pore size distribution curve, the accumulated pore volume of pores having radii in the range of “a” ±25 Å is at least 65% of the total volume of all the pores, the alumina containing less than 1% by weight of rare earth elements and being loaded with one or more elements of the platinum group. A process for removing organic compounds, the process including the step of contacting organic compounds with either one of the above catalysts.
