Abstract

Abstract

Manganese-cerium composite oxides catalyst was prepared with zeolite as the carrier. The binary catalytic performance of the catalyst for industrial typical VOCs was investigated, and the catalyst was characterized by BET, XRD and SEM. Results showed that the addition of the cerium promoted the dispersion of the manganese and improved the activity of the composite oxide catalyst.The catalytic performance of MnCeO_x/zeolite was the best with n(Mn)∶n(Ce) of 1∶1, loading ratio of 20% and calcination temperature of 500 ℃, with initial and complete combustion temperatures of toluene at 155 ℃ and 255 ℃, respectively. In the single component experiment, the catalysts for three organics all showed higher activity, and the temperature of conversion of 90% was below 275 ℃; the catalytic performance decreased in the order of ethyl acetate, toluene and acetone, which was mainly affected by the level of the activation energy as well as their polarity of molecule. In the binary catalytic experiment, T₅₀ and T₉₀ of three organics increased respectively by 8~13 ℃ and 14~38 ℃ than that in the single component experiment, due to the competitive adsorption.
