    • The object of the present invention is to provide a catalyst regeneration process which can improve catalyst selectivity. A first aspect of the invention is characterized in that a spent catalyst from a reactor is introduced into a first fluidized bed regenerator and contacted with an oxygen-containing gas stream and optional steam to carry out a coke combustion reaction, wherein the resultant mixture of the partially regenerated catalyst and flue gas is introduced into a second fluidized bed regenerator and contacted with steam and an optional oxygen-containing gas stream to carry out a further regeneration reaction, and then the regenerated catalyst is introduced into the reactor. A second aspect of the invention is characterized in that a spent catalyst from a reactor is introduced into a fluidized dense bed regenerator and contacted with an oxygen-containing gas stream and steam to carry out a coke combustion reaction, and then the regenerated catalyst is introduced into the reactor. The inventive processes result in a more uniform distribution of the regenerated catalyst activity; due to the exposure of the catalyst to a low temperature for a long time, a part of the heavy metals are buried by the matrix and the remaining are passivated. Thereby dry gas and coke yields decrease sharply when hydrocarbons are subjected to a catalytic cracking reaction on the regenerated catalyst.
    • 本发明的目的是提供一种能够提高催化剂选择性的催化剂再生方法。 本发明的第一方面的特征在于将来自反应器的废催化剂引入第一流化床再生器中并与含氧气流和任选的蒸汽接触以进行焦炭燃烧反应,其中所得的 将部分再生的催化剂和烟道气引入第二流化床再生器中,并与蒸汽和任选的含氧气流接触以进行进一步的再生反应,然后将再生催化剂引入反应器。 本发明的第二方面的特征在于将来自反应器的废催化剂引入流化密床再生器中并与含氧气流和蒸汽接触以进行焦炭燃烧反应,然后引入再生催化剂 进入反应堆。 本发明的方法导致再生催化剂活性的更均匀分布; 由于催化剂长时间暴露于低温下,部分重金属被基质掩埋,其余的被钝化。 因此当烃在再生催化剂上进行催化裂化反应时,干气和焦炭产量急剧下降。

    • 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.
