表层中毒C207联醇催化剂的效率因子

Effectiveness Factors of Surface Poisoned C207 Catalyst

本文提出了表层中毒Ｃ２０７联醇催化剂效率因子的单组分模型和多组分模型的一维正交配置解，表层中毒深度由实验测定的失活速率方程求得。计算结果表明：随硫化氢含量和使用时间增加，催化剂效率因子减小；随反应温度升高，表层中毒深度增加，又受内扩散影响，催化剂效率因子明显减小。

The single component model and the multicomponent model of the effectiveness factor of the surface poisoned C207 methanol synthesis catalyst were presented and solved by one-dimensional orthogonal collocation method. The depth poisoned by hydrogen sulfide was calcutated by the intrinsic deactivation rate equation. The calculation results indicated that the effectiveness factors decrease with the increase of the H_2S and the time;the poisoned depth of catalyst increases with the increase of the reaction temperature and the effectiveness factors severely decrease because of the limiting of the intraparticle diffusion.
