本文主要结合实验,展开对甲醇制稀烃反应催化剂再生动力学的探究。通过失活SAPO-34催化剂的烧炭再生动力学模型的分析,构建相关的宏观动力学模型,这样就可以得到模型获取动力学的相关参数,进而以参数为基准展开合理的分析,如果分析数据与参数相接近,就可以进行其他数据的验证,但要确保计算后产生数据与实际数据误差控制范围在5%以内,这样才可以保证宏观动力学模型可靠。其次,要对化学试剂对外扩散产生的影响进行试验,结合甲醇制稀烃反的主要结构和实际的性质,确反应工程原理,这样就可以确定甲醇稀烃扩散有效系数为0.75,扩散效果较为明显,必须要降低扩散,避免其对反应效率产生影响。
In this paper, the main combination of experiments, expand the catalyst for the methanol-made rare-earth catalyst regeneration kinetics. Through the analysis of charcoal regeneration kinetics model of inactivated SAPO-34 catalyst, the related macroscopic kinetic model is constructed, so that the kinetic parameters of the model can be obtained and then the rational analysis can be carried out based on the parameters. If the analysis data Close to the parameters, you can verify other data, but to ensure that the calculated data and actual data error control within 5%, so as to ensure that the macro-dynamic model is reliable. Secondly, to test the influence of chemical diffusion on external diffusion, combined with the main structure and actual properties of methanol-made rare-earth reaction, it is confirmed that the effective coefficient of diffusion of methanol and rare-earth hydrocarbon is 0.75 and the diffusion effect is obvious , We must reduce the proliferation, to avoid its impact on the efficiency of the reaction.
