摘要：针对二氧化碳加氢生产甲醇的轴向反应器,建立了一维拟均相数学模型,采用Runge-Kutta法求解数学模型。对二氧化碳加氢反应动力学模型中的各参数进行了修正拟合,通过MatlabR软件计算了二氧化碳加氢反应器中的反应情况,并优化了反应器的操作参数,得到了较优的反应器操作条件:进料n(CO2):n(H2)为1:4、n(CO2):n(CO)为10:1、温度为235℃,管外换热水温度230℃,单管进料速度为2.1 mol/s。在此条件下,二氧化碳的转化率为17.9%,目标产物甲醇的选择性为72.8%,单套生产能力为300 kt/a,为工业化反应器设计提供了理论支持。
A one-dimensional quasi homogeneous mathematical model of axial reactor for hydrogenation of carbon dioxide to methanol was established and calculated by the Runge-Kutta method.The hydrogenation kinetic parameters were calculated and fitted.Hydrogenation of carbon dioxide to methanol in axial reactor was studied by MatlabR,and the operating parameters of the reactor were optimized.The optimal operating conditions of the reactor were obtained as follows:feed gas CO2/H2 molar ratio of 1:4,CO2/CO molar ratio of 10:1 and temperature of 235℃;hot water temperature outside the tube of 230℃;and the feed rate of single tube is 2.1 mol/s.Under these conditions,the conversion of carbon dioxide is 17.9%,the selectivity of methanol is 72.8%,and the capacity of one axial reactor is 300 kt/a.The results provides a theoretical support for industrial reactor design.
