环境污染的治理是人们关心的问题。催化燃烧是废气处理的有效方法,关键是寻找好的燃烧催化剂。1972年,Voorhoeve等首先提出用钙钛矿型稀土催化剂作为汽车排气净化催化剂。由于稀土钙钛矿结构稳定,A、B两种离子可在较大范围内选择,此类催化剂引起了广泛的注意。前人除较多地研究了CO的催化燃烧外,对于碳氢化合物曾研究过苯、丙烷在稀土钙钛矿催化剂上的深度氧化,但未见丁烯-1的深度氧化的研究报道。此外,本文催化反应器的设计,反应条件最佳化的选择与控制都以催化动力学为基础。
Environmental pollution control is a matter of concern. Catalytic combustion is an effective method of exhaust gas treatment, the key is to find a good catalyst for combustion. In 1972, Voorhoeve et al. First proposed perovskite type rare earth catalyst as an automobile exhaust gas purification catalyst. Due to the stable structure of rare earth perovskite, A and B ions can be selected in a wide range. Such catalysts have drawn wide attention. In addition to the previous studies on the catalytic combustion of CO, we have studied the deep oxidation of benzene and propane over rare earth perovskite catalysts for hydrocarbons, but no deep oxidation of butene-1 has been reported. In addition, the design and optimization of reaction conditions in this paper are based on catalytic kinetics.
