一种甲苯催化燃烧整体式催化剂的制备方法与应用
摘要：
本发明提供了一种甲苯催化燃烧整体式催化剂的制备方法与应用，所述催化剂为Pd基催化剂，所述催化剂的载体为CeO2-Pr6O11/Al2O3，通过对不同Ce/Pr摩尔比的CeO2-Pr6O11混合氧化物进行了研究，寻找高活性的最佳Ce/Pr比例，其中当Ce/Pr=4:1时，催化剂表现了最好的甲苯催化氧化活性。本发明具有催化性能良好、贵金属含量低、热稳定性好、涂覆更均匀的特点。
摘要（英）：

The invention provides a method for preparing toluene catalytic combustion monolithic catalysts and application. The toluene catalytic combustion monolithic catalysts are Pd-based catalysts, a carrier for the toluene catalytic combustion monolithic catalysts is CeO2-Pr6O11/Al2O3, CeO2-Pr6O11 mixed oxide with different Ce/Pr molar ratios is researched, accordingly, the optimal Ce/Pr proportions of the CeO2-Pr6O11 mixed oxide with the highest activity are found, and the toluene catalytic combustion monolithic catalysts are optimal in toluene catalytic oxidation activity when the Ce/Pr proportions are equal to 4:1. The method and the application have the advantages of excellent catalytic performance, low precious-metal content, good thermal stability and uniform coating.
