本文在常压下用直流管式等温积分反应器研究了C301型铜基催化剂上CO-H_2-CH_3OH 系统中甲醇分解反应本征动力学。在不同温度和组成的情况下测定了甲醇分解的速率。用非线性最小二乘法对幂函数型甲醇分解反应本征动力学模型进行了参数估值,得到甲醇分解的动力学方程为:R_m=-(dN_m)/(dW)m=0.3202×10~(10)exp(-(26610)/(R_gT))p_(H_2)~(-0.25)p_(CO)~(-0.25)p_m~(0.5)mol/(g·hr)由甲醇分解反应的活化能求得合成反应的活化能为14990 cal/mol。
In this paper, the intrinsic kinetics of methanol decomposition in CO-H_2-CH_3OH system on C301 copper-based catalyst was investigated by using a direct current tubular isothermal reactor at atmospheric pressure. The rate of methanolysis was determined at different temperatures and compositions. The kinetic equation of methanol decomposition was obtained by nonlinear least squares method. The kinetic equation of methanol decomposition was obtained as follows: Rm = - (dNm) / (dW) m = 0.3202 × 10 ~ 10) exp (- 26610) / (R_gT)) p_ (H_2) -0.25 p CO (-0.25) p m ~ (0.5) mol / (g hr) is calculated from the activation energy of the methanolysis reaction The activation energy of the synthesis reaction was 14990 cal / mol.
