表面中毒甲醇成催化剂效率因子

对ＣＯ、ＣＯ２加氢合成甲醇平行反应提出了表面中毒催化剂效率因子的关键组分计算模型，并用正交配置法求解．硫化氢表面中毒深度由失活速率方程求得．计算结果表明。随Ｈ２Ｓ含量增加和使用时间增加，催化剂效率因子减小；随反应温度升高，表面中毒深度增加，又受内扩散影响，催化剂效率因子明显减小．

The catalytic effectiveness factor of methanol synthesis catalyst subjected to surface poisoning

A calculation model for the key comPOnents influencing on the catalytic effectiveness factor of catalyst with surds poisoning has been put forward with regard to the parallel methanol synthesis reactions of hydrogenation of CO and CO2. The solution was obtained by orthogonal array method. The surface POisoning depth by hydrogen sulfide was derived from its equation of deactivation rate. The results indicate that the catalytic effectiveness factor of catalyst will decrease,as the HZS content and the service time increase,further' more,tbe catalytic effectiveness factor will be decreased significantly with the reaction temperature,surface POisoning depth as well as the inner-diffusion effect being increased
