【摘要】 本文通过在MoO3上添加不同金属氧化物,制备了系列含低熔点物质的催化剂,利用程序升温控制反应,研究了这些催化剂分别在碳烟和催化剂的紧接触和松接触的不同条件下对柴油机尾气中碳烟和NOx的同时催化去除性能,研究表明具有流动性好的氧化物催化剂能改善接触,提高催化活性。更多还原

【Abstract】 MnO3-based catalysts with different additions of metal oxides were prepared. The catalytic performances of there catalysts for diesel soot oxidation and NOx reduction were investigated with temperature-programmed reaction. It is shown that the contact condition between soot and catalyst is an important parameter, and the catalysts that are mobile are able to increase the catalytic activity.更多还原
