摘要
采用等温流动积分反应器，在下列条件范围内：反应温度３６０℃～３９０℃，压力０．１ＭＰａ～４．０ＭＰａ，重量空速５．０ｈ￣－１～１１．Ｏｈ￣－１、对甲酵在ＺＳＭ－５分子筛催化剂上转化制汽油反应进行了研究。根据实验结果，对Ｍｔｈａｉｌ￣［１］提出的甲醇转化成烃类机理做了某些修正。建立了甲醇在ＺＳＭ－５分子筛催化剂上转化成汽油的动力学模型，该模型是一个包括２６个方程的常微分方程组。用Ｇｅａｒ法求解此方程组，用Ｐｏｗｅｌｌ法和Ｍａｒｑｔｉａｒｄｔ法相结合的方法对实验数据进行了回归，求出了每个反应的活化能和指前因子。用此模型预测反应结果，计算值与实验值相符合较好。
The methanol to gasoline reaction over ZSM-5 zeolite catalyst was studied inan isothermal integral reactor in the range of temperature(360℃～390℃),pressure(0.1MPa～4.0MPa),and weight space velocity (5.0h￣-1～11.0h￣-1). According to the experimental re-sults, some modifications to the kinetic mechanism of MTG proposed by mihail were sug-gested.A new complex reaction network consisting of 50 reactions involving 26 chemicalspecies was proposed.A kinetic model for MTG composed of 26 ordinary differentiai equa-tions was developed.The activation energies and preexponential factors for every reactionswere estimated by regression of experimental data using Powell method followed by Mar-quardt method.The kinetic model was used to predict the MTG reaction and satisfactory a-greement was obtained between the calculated and experimental data.
