以VPO催化剂上正丁烷选择氧化制顺酐为例 ,对以变价金属复合氧化物为催化剂、按照氧化 -还原机理进行的一大类烃类选择氧化反应催化循环的温度匹配问题进行了初步模拟 .结果表明 ,使烃类选择氧化 (催化剂被还原 )和催化剂氧化再生分开进行 ,特别是根据催化剂氧化再生动力学的要求 ,适当调节再生过程的温度 ,既能明显改善反应系统的性能 ,又可以大幅度降低催化剂固体颗粒的循环量 ,取得节能降耗的效果 .本文介绍模型的建立和求解方法
Taking the selective oxidation of n-butane to maleic anhydride over VPO as an example, a preliminary simulation was performed on the temperature matching of a large class of hydrocarbon selective oxidation catalytic cycles with variable-valent metal composite oxide as a catalyst in accordance with the oxidation-reduction mechanism The results show that selective oxidation of hydrocarbons (catalyst reduction) and catalyst oxidation regeneration separately, especially according to the requirements of catalyst oxidation and regeneration kinetics, proper regulation of the regeneration process temperature can not only significantly improve the performance of the reaction system, but also Greatly reduce the circulation of catalyst solid particles, to achieve the effect of saving energy and reducing consumption.This article describes the model establishment and solution method
