摘　　要：研究了FCC汽油中C5馏分合成甲基叔戊基醚(TAME)的宏观动力学。C5原料与甲醇摩尔比为1/1,在温度分别为55℃～90℃时反应得到了动力学实验数据。采用非线性曲线拟合方法处理实验数据,建立了叔戊烯醚化反应动力学方程,并对活化能的变化进行了分析。用动力学模型求得的计算值与实验值比较,结果表明相对误差均小于5%,说明所建动力学模型能较好地描述叔戊烯醚化反应,且具有良好的外推性。The kinetics of tertamyl methyl ether （TAME） synthesis using C5 fraction of FCC gasoline was studied. The molar ratio of tertiary amylene to methanol was 1.0 and the kinetic experimental data was obtained at the temperature range from 55℃ to 90℃. The nonlinear curve fitting method was adopted to deal the experimental data. The kinetic equation was established and the change of activation energy was analyzed. Compared the calculated values with the experimental values, the relative error all less than 5%. This showed that the kinetic equation could preferably describe the etherification reaction and had a favorable extrapolation.
