采用磁力搅拌内循环无梯度反应器在 5MPa、 2 30～ 2 70℃和气体组成 (摩尔分率 ) CO0 .0 391～ 0 .1 72 3,CO2 0 .0 0 55～ 0 .1 2 38,H2 0 .5840～ 0 .7349(余为 N2 和 CH4 )条件下 ,对国产 NC30 6型铜基甲醇合成催化剂的低压宏观动力学特性进行了实验研究。基于 CO、CO2 竞争加氢双路线合成甲醇反应模式 ,以 Simplex- Powell复合法对实验数据进行搜索、寻优 ,建立了 NC30 6催化剂的宏观动力学模型。统计检验结果表明 ,所建模型良好地吻合了实验结果 ,是适宜和可信的。 The magnetic stirring internal circulation non-gradient reactor was used at 5MPa, 230 ~ 270 ℃ and gas composition (mole fraction) CO0.0391 ~ 0.1272, CO2.0.055 ~ 0.1238, H2 0 .5840 ~ 0 .7349 (the balance of N2 and CH4) under the conditions of domestic NC306 copper-based methanol synthesis catalyst macroscopic kinetic characteristics of low-pressure experiments were carried out. Based on the CO2 and CO2 competition hydrogenation methanol synthesis reaction mode, the experimental data were searched by Simplex-Powell complex method and optimized. The macromodelical model of NC306 catalyst was established. Statistical test results show that the model is in good agreement with the experimental results, is appropriate and credible.
