摘　　要：进行了催化裂化轻汽油(HK^75℃)中C5烯烃与甲醇反应生成甲基叔戊基醚的宏观动力学研究,在消除外扩散影响的前提下,得出轻汽油中C5烯烃醚化的反应速率方程和其他动力学参数,并对所建的动力学模型进行了实验检验。结果表明:在不同的液体空速及反应温度下,叔戊烯醚化转化率计算值与实验值的相对误差均小于5%,所建模型高度显著,可实现对实际工艺操作过程的模拟。Macrokinetics on etheriflcation reaction between methanol and C5 olefin in fluid catalytic cracking light gasoline ( HK ~ 75℃) to form methyl tert - amyl ether was studied. The reaction rate equation and other kinetics parameters were set up and also verified under the condition of eliminating the influence of external diffusion. The results showed that the relative errors of trimethylacetic olefin etheriflcation conversion between calculated value and experimental data were less than 5% respectively under the different liquid hourly space velocity and reaction temperature. The model was remarkable highly and could be applied to simulation of the actual processing operation of C5 olefln etheriflcation.
