制备了负载型钙钛矿型复合氧化物ＡＢＯ３／ＣａＯ（Ａ和Ｂ位分别由两种不同组份调变）系列催化剂，采用Ｘ－光衍射分析仪、固定床微型反应装置和热重分析仪对其物相结构、ＣＯ催化氧化能力和烧炭助燃性能进行了系统的表征和评价。结果表明，此催化剂的ＣＯ氧化活性在高温区略低于现行的铂系助燃剂，而烧炭速度和去焦能力却优于铂系助燃剂。根据这些试验结果对表观烧炭动力学进行了初步探讨，证明当加入此催化剂时，在分子筛含炭量较高的烧炭初期，催化烧炭过程符合一级动力学方程，给出了烧炭表观动力学常数。
Preparation of a supported perovskite type composite oxide ABO3 / CaO (A and B bits were modulated by two different components) series of catalysts, using X-ray diffraction analyzer, fixed bed microreactor and thermogravimetric analyzer The phase structure, catalytic oxidation of CO and char combustion performance were systematically characterized and evaluated. The results showed that the CO oxidation activity of the catalyst was slightly lower than that of the current platinum catalyst in the high temperature range, but the charcoal burning rate and the decoking ability were superior to those of the platinum catalyst. According to the results of these experiments, the kinetics of apparent charcoal burning was preliminarily discussed. It was proved that when the catalyst was added, the catalytic combustion of charcoal was in accordance with the first-order kinetic equation at the initial stage of charring with high charcoal content, Carbon apparent kinetic constants.
