加工劣质原料油增产丙烯专用催化剂设计

为了扩大催化裂化进料来源,中山天乙石化公司在该公司产量为40万t/a的催化裂化装置上加工M-100类劣质原料油,该类原料油性质较差、金属含量高、裂化难度大,因此,对所使用的催化剂提出了苛刻的要求。中石化石油化工研究院(RIPP)和中石化催化剂长岭分公司设计并生产出该装置所专用的催化剂CMO,经实验评价,CMO具有很好的活性和活性稳定性、优异的抗金属污染性能、优秀的重油转化能力,能有效地增产丙烯。

A special catalyst designing for increasing propylene from inferior crude oil

For expanding the RFCC's feedstock, Zhongshan Tianyi Petrochemical Co., Ltd. has to process some kinds of inferior crude oil like as M-100 with the characteristic of bad properties, high content of metal and difficult cracking in the fluidized catalytic cracking set with the output of 400 000 t/a. Therefore the catalyst used in the RFCC unit is required grindingly. The special catalyst, CMO, is designed and manu-factured for this unit by Sinopec research institute of petroleum processing (ab.as RIPP) and Sinopec catalyst company Changling Division according to the rule of customer-making. The evaluation shows that the catalyst CMO has good activity and stabilization, excellent anti-metal contamination and outstanding capacity of processing inferior crude oil. The said catalyst is effective to increase the propylene.
