研究了甲醇合成C207铜基催化剂硫化氢中毒本征失活动力学。常压下在内循环无梯度反应器中测定了φ5×5mm工业颗粒C207铜基催化剂在进门硫化氢含量7.19×10~(-4),分别通硫化氢4、8和12小时后甲醇分解反应宏观速率。俄歇电子能谱测定结果表明,工业颗粒铜基催化剂硫化氢中毒为表面中毒,通硫化氢4、8和12小时未中毒比半径分别为0.938,0.916和0.896,与由本征失活动力学计算的值相符合。 Intrinsic kinetics of hydrogen sulfide poisoning of methanol synthesis C207 copper-based catalyst was studied. Atmospheric pressure in the inner loop without gradient reactor was measured φ5 × 5mm industrial particles C207 copper-based catalyst in the door hydrogen sulfide content of 7.19 × 10 -4, respectively, hydrogen sulfide 4, 8 and 12 hours after the methanolysis reaction Macro rate. Auger electron spectroscopy measurement results show that industrial particle copper-based catalyst hydrogen sulfide poisoning is surface poisoning, hydrogen sulfide 4, 8 and 12 hours without poisoning radius ratio were 0.938,0.916 and 0.896, respectively, and calculated by the intrinsic inactivation kinetics The values ​​match.
