摘要： The present invention provides a catalytic cracking catalyst, processing method and use thereof. When the catalyst is added into a commercial catalytic cracking unit, it has an initial activity of not higher than 80, preferably not higher than 75, more preferably not higher than 70, a self-balancing time of 0.1-50 h, and an equilibrium activity of 35-60. Said method enables the activity and selectivity of the catalyst in the catalytic cracking unit to be more homogeneous and notably improves the selectivity of the catalytic cracking catalyst, so as to obviously reduce the dry gas and coke yields, to sufficiently use steam and to reduce the energy consumption of the FCC unit.

摘要： The present invention relates to a catalytic conversion process for improving the product distribution, characterized in that a feedstock oil of good quality is contacted with a hot regenerated catalyst having a lower activity in a reactor to carry out a cracking reaction, the reaction product is separated from the spent catalyst to be regenerated, then the reaction product is fed into a separation system, and the spent catalyst to be regenerated is stripped, regenerated and recycled in the process. The isobutene content in the liquefied petroleum gas (LPG) produced by the process is increased by a factor of more than 30%, and the olefin content in the gasoline composition may be increased to more than 30 wt. %. The product distribution is optimized, and the yields of dry gas and coke are decreased, so as to sufficiently utilize the petroleum resources.
摘要翻译：本发明涉及一种用于改善产物分布的催化转化方法，其特征在于将质量好的原料油与反应器中具有较低活性的热再生催化剂接触以进行裂解反应，将反应产物分离从待再生的废催化剂中，然后将反应产物进料到分离系统中，将待再生的废催化剂在该过程中被汽提，再生和再循环。通过该方法生产的液化石油气（LPG）中的异丁烯含量增加了大于30％，并且汽油组合物中的烯烃含量可以增加到大于30wt。％。产品分布优化，干气和焦炭产量下降，充分利用石油资源。
