摘　　要：采用内循环无梯度反应器,在YL-Ⅰ型MTBE裂解制异丁烯催化剂上进行了反应动力学研究,首先完成无梯度验证和排除内扩散效应,然后通过改变反应温度、原料组成和接触时间,得到一系列动力学数据。用线性最小二乘法进行模型的筛选和参数估值,并经过方差分析、F检验后,确认了反应动力学表达式。The reaction kinetics of methyl tertiary-butyl ether cracking for isobutylene over the commercial catalyst YL-1 was studied by varying the feed composition and residence time in a temperature range of 155-215℃ using an internal circulation gradientless reactor, and a series of kinetic data was obtained. By using the linear least-square fitting method for evaluation of kinetic parameters and inspected through square error analysis and F test, a rate equation is proposed.
