Catalysts for removing organic compounds from a gas stream containing the same and processes for removing organic compounds from the gas stream using the cataylst are disclosed.According to the first aspect, a combustion catalyst for removing organic compounds comprises a mixture of a zeolite and a metal oxide containing at least one of the elements of the platinum group. According to the second aspect, a combustion catalyst for removing organic compounds 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 accumlated pore volume of pores having radii in the range of "a"±Å is at least 65% of the total volume of all the pores, said alumina containing less than 1% by weight of rare earth elements and being loaded with one or more elements of the platinum group.According to third aspect, there is a process for removing organic compounds, said process comprising the step of contacting organic compounds with either one of the catalysts according to the first and second aspects of the invention.
