    Abstract: Systems and methods for upgrading hydrocarbons are provided. A first hydrocarbon can be cracked in the presence of one or more catalysts to provide a first cracked mixture containing one or more light cycle oils (LCOs) and one or more coked catalysts. A second hydrocarbon, containing one or more C4 to C20 hydrocarbons and having a Research Octane Number of less than 88, can be mixed with the one or more catalysts to provide a first mixture at a second temperature. A third hydrocarbon can be combined with the first mixture to provide a second mixture. The second mixture can be cracked to provide a second cracked mixture containing propylene, one or more mixed hydrocarbons in the gasoline boiling range having a Research Octane Number greater than 88, and one or more coked catalysts. The first cracked mixture and second cracked mixture can be combined to provide a third mixture.

    Abstract: The conventional wye (where the clean regenerated catalyst returns from the regenerator to contact the feed as it enters the riser) is replaced with two or more wyes, all connected between the regenerator outlet and the inlet to a common short cracking riser. Each wye has a separate injector which can inject; e.g., diesel oil, so that neat (unmixed) diesel contacts clean catalyst and the mixture rises up a smaller riser before entering a short main riser where the largely cracked mixture is admixed with similar cat-vacuum bottoms, etc. mixtures from the other wyes. Most cracking occurs before entering the common riser so the effect is similar to a riser cracker operating on a single unmixed feed.

    Abstract translation: 传统的叶片（其中清洁的再生催化剂从再生器返回到进料器进入提升管时与进料接触）用两个或更多个叶片代替，所有两个或多个叶片全部连接在再生器出口和入口之间以连接到共同的短裂纹提升管。 每个眼睛都有一个可注射的单独注射器; 例如柴油，使得整齐的（未混合的）柴油接触清洁的催化剂，并且混合物在进入短的主提升管之前升高较小的提升管，其中将大部分裂化的混合物与类似的真空底部等混合， 。 大多数裂纹发生在进入普通提升管之前，因此效果类似于在单个未混合进料上操作的提升裂解器。

    Abstract: A catalytic cracking process is disclosed which comprises:(a) thermally and/or catalytically cracking a hydrogen-rich hydrocarbon feed in the lower region of a riser reactor in the presence of a catalyst composition comprising a first catalyst component, and, optionally, a second catalyst component, said first catalyst component being an amorphous cracking catalyst and/or large pore crystalline cracking catalyst, said second catalyst component being a shape selective medium pore crystalline silicate zeolite catalyst, to provide a gasiform material contributing hydrogen species and/or carbon-hydrogen fragments; and,(b) catalytically cracking a thermally treated heavy hydrocarbon feed in a higher region of the riser in the presence of said catalyst composition and gasiform material to provide gasoline boiling range material in increased yield and/or of higher quality.
