Combined oxide catalysts are prepared for catalytic combustion of soot and regeneration from diesel emissions. Thermo-gravimetric analysis(TGA) and temperature programmed oxidation(TPO)are used to evaluate the activity of catalysts under the influence of composition,atomic ration, H2O, calcinations temperature and mass ration between catalysts and soot. Results show that Cu-Mo-O had high activity among double metal oxide catalysts. Among multicomponent metal oxide catalysts, Cu-K-Mo-O had high activity when atomic ratio Cu: K: Mo = 1:1:2 and mass ration between catalysts and soot equals 5: 1. Under this condition, soot ignition temperature of Cu-K-Mo-O catalyst was 327 degrees C. H2O addition and calcinations temperature had little influence on it,which is one kind of compatible catalyst for soot control and catalytic regeneration from diesel emissions.
制备了用于催化燃烧碳烟和柴油机排放物再生的复合氧化物催化剂。采用热重分析（TGA）和程序升温氧化（TPO）来评估催化剂在组成、原子比、H₂O、煅烧温度以及催化剂与碳烟之间的质量比影响下的活性。结果表明，在双金属氧化物催化剂中，Cu-Mo-O具有较高活性。在多组分金属氧化物催化剂中，当原子比Cu:K:Mo = 1:1:2且催化剂与碳烟之间的质量比等于5:1时，Cu-K-Mo-O具有较高活性。在此条件下，Cu-K-Mo-O催化剂的碳烟着火温度为327℃。添加H₂O和煅烧温度对其影响较小，它是一种用于控制碳烟和柴油机排放物催化再生的兼容催化剂。
