建立了ＭＦＴ合成（ＭｏｄｉｆｉｅｄＦｉｓｃｈｅｒＴｒｏｐｓｃｈＳｙｎｔｈｅｓｉｓ）工艺中ＺＳＭ５分子筛催化剂上转化的结焦动力学模型，获得了合理的模型参数，模型计算值与实验值的相对误差在±１０％以内。利用所建动力学模型可以准确地预测ＭＦＴ工业改质反应器出口附近催化剂上的焦含量。根据获得的动力学模型及模型参数的意义，对结焦机理进行了探讨
The kinetic model for the conversion of ZSM5 molecular sieve catalyst in MFT synthesis (Modified FischerTropschSynthesis) process was established. The reasonable model parameters were obtained. The relative errors between calculated and experimental values were within ± 10%. The dynamic model can be used to predict the coke content on the catalyst near the exit of MFT industrial upgrading reactor. According to the kinetic model and the significance of the model parameters, the coking mechanism is discussed
