摘要：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。
The intrinsic deactivation kinetics of methanol synthesis C 207 Cu--based catalyst poisoned by hydrogen sulfide has been studied.The activity is expressed with the relative value of methanol decomposition rate at atmospheric pressure.After the addition of inlet H2S content 7.19×10-4 for 4,8 and 12 hours respectively,the methanol decomposition reaction global rates of 5×5 mm cylindrical catalyst pellets have been measured at atmospheric pressure in an internal recycle gradient less reactor.The poisoning of commercial catalyst by H2S is surface poisoning.The experimental values of non-poisoned dimensionless radius determined by Auger electron spectroscopy are 0.938,0.916 and 0.896 respectively with the addition of H2S for 4 ,8 and 12 hours,they are coincident with the calculated values by the intrinsic deactivation kinetics.
