摘　　要：2017年4月,由中国石油石油化工研究院自主开发的PEC-21前加氢催化剂在中国石油大庆石化公司270 kt/a的乙烯装置上进行了工业应用试验。PEC-21催化剂装填于一段反应器,不注入CO直接开工,运行4 h后产出合格产品,具有优异的开工稳定性。该装置已连续运行180 d以上,催化剂提温速率慢,能够满足长周期稳定运行的要求。标定结果表明,乙炔平均转化率为55.8%、乙烯平均选择性为95.4%、丙烯平均选择性为96.3%,优于技术协议考核指标,可满足装置的生产需求。In April 2017,acetylene front-end hydrogenation catalyst PEC-21 developed by Petrochemical Research Institute of Petrochina was carried out on the 270 kt/a ethylene plant of Daqing Petrochemical Company.PEC-21 catalyst was loaded in the first reactor by using of non-CO go into operation.After 4 h,export products qualified.The catalyst has good starting stability,continuous operation for more than 180 d,the catalyst’s temperature growth rate is slow,meeting long-term stable operation requirements.The calibration results show that the average conversion of acetylene is 55.8%,ethylene selectivity is 95.4%,and propylene selectivity is 96.3%,which is better than that of technical agreement.
