甲醇脱水制二甲醚的动力学与催化剂粒内效率因子

Study on Kinetics of Methanol Dehydrolyzing to DME and Effectiveness Factors of the Catalyst

测定了常压下ＣＭ－３－１催化剂上甲醇气相法脱水生成二甲醚的本征与宏观反应速率，得到幂函数型本征动力学方程，提出了计算催化剂粒内效率因子的两维正交配置方法。所得效率因子的计算值与实验值吻合。

The intrinsic and global reaction rates of methanol dehydrolyzing to dimethyl ether on CM-3-1 catalyst by gas phase method were determined under atmospheric pressure and power type kinetic equation was obtained. The calculation results of effectiveness factors obtained by two-dimension orthogonal collocation method fit to experimental data well.
