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 kinetics of the reaction was studied on a YL-Ⅰ MTBE pyrolysis isobutylene catalyst using an inner loop gradientless reactor. First, the gradient-free validation and exclusion of internal diffusion were performed. Then, by changing the reaction temperature, the composition of the raw materials and the contact time, A series of kinetic data. The linear least square method was used to select the model and estimate the parameters. After analysis of variance and F test, the reaction kinetic expression was confirmed.
