    • An FCC process for obtaining light olefins comprises contacting a hydrocarbon feed stream with blended catalyst comprising regenerated catalyst and coked catalyst. The catalyst has a composition including a first component and a second component compring a zeolite with no greater than medium pore size wherein the zeolite comprises at least 1 wt-% of the catalyst composition. The hydrocarbon feed stream is in contact with the blended catalyst in a riser for less than or equal to 2 seconds on average. A first portion of the coked catalyst is passed to a regeneration zone, while a second portion of the coked catalyst is blended with the regenerated catalyst and introduced to the riser.
    • 用于获得轻质烯烃的FCC方法包括使烃进料流与包含再生催化剂和焦化催化剂的混合催化剂接触。 催化剂具有包含第一组分和第二组分的组合物,该组分包含不大于中等孔径的沸石,其中沸石包含至少1重量%的催化剂组合物。 烃进料流在提升管中与混合的催化剂平均接触小于或等于2秒。 将焦化催化剂的第一部分通入再生区,同时将第二部分的焦化催化剂与再生催化剂混合并引入提升管。
