摘要

A series of Ce-Ni-Mn-O catalyst samples supported on cordierite honeycomb were prepared by the citric acid wet impregnation method with using Ce(NO₃)₂, Ni(NO₃)₂ and Mn(NO₃)₂. The effects of the molar ratio on Ce, Ni and Mn, calcinations temperature and time for the complete oxidation of benzene were investigated. The catalysts were characterized by specific surface area (BET), scanning electron microscope (SEM) and X-ray diffraction techniques (XRD). The results showed that the Ce-Ni-Mn-O complex oxides catalysts with Ce, Ni and Mn molar ratio of 1:0.5:0.5, calcining at 500°Cand 7 h exhibited high catalytic performance. With the concentration of benzene of 4.8 g/m³ and the gaseous hourly space velocity of 15000 h^-1, the conversion of toluene was 91.8% at the reaction temperature of 300°C.
