| Abstract: | The operation of C2 front-end hydrogenation catalyst PEC-21 which developed by Lanzhou Petrochemical Research Center,PetroChina,was investigated in the 1st stage reactor of 0.8 Mt/a ethylene plant of Sichuan Petrochemical Co Ltd.The catalyst PEC-21 was calibrated and its long cycle operation was analyzed.The results showed that during the calibration of PEC-21 catalyst in the 1st stage reactor,the average conversion rate of acetylene was 62.94%and the average selectivity of ethylene and propylene were 96.03%and 95.64%respectively.After PEC-21 catalyst was operated for 2 a,the average conversion rate of acetylene and the average selectivity of ethylene were 54.60%and 91.80%,respectively. |
