Abstract: Ru/ZSM-5,a ruthenium-based catalyst,is prepared by impregnation method with ZSM-5 molecular sieve as support.Its properties in catalytic oxidation of toluene is studied at different concentrations and at different space velocity.Its stability and selectivity to CO2 are discussed.It is indicated that the catalyst has a good stability and an excellent selectivity for CO2,and higher space velocity and concentration will reduce the catalytic activity of the catalyst.Under experimental conditions,the lowest T90 value of catalytic oxidation of toluene over Ru/ZSM-5 is 161℃,and the catalyst shows superior catalytic oxidation performance to toluene at low temperature in a large space velocity range.
