The Effect of the Preparation Conditions of Al₂O₃ Support to Catalysts for Diesel Particulate Removal from Exhaust Gases

Abstract:

A study has been conducted on the preparation conditions of Al₂O₃ for the catalysts for diesel particulate matter. The results show that the preparation conditions of Al₂O₃ support had great contribution to performance of Sn-Cu-K-V/Zr0₂-Al₂O₃ catalyst. The conditions of precipitant, pH value and calcination temperature were investigated. The experiment results show that the suitable precipitant was Na₂CO₃, the pH value of the solution was 9 and calcination temperature was 1000°C. The catalyst which active components were loaded on the modified support by immersion method showed better catalytic activity.
