| Abstract: | Five monolithic catalysts with low noble metal content were prepared by immerge method (Pt/γ-Al2O3, Pt/La-Al2O3, Pt/YSZ-Al2O3, Pt Pd/La-Al2O3 and Pd/ La-Al2O3) and their activity measurements were carried out in a conventional fixed-bed flow reactor. The results show that La-Al2O3 can promote activity of the prepared catalysts and can decrease the complete conversion temperature of cooking fume. The Pt/La-Al2O3 catalyst has the highest activity and can be applied in wide range of gas hourly space velocity (GHSV). Some characterizations (XRD, TPR) were carried out with the objective to explain differences in catalytic behaviors. The prepared catalyst shows great potential for application. |
