PROCESS FOR MAKING A DISTILLATE PRODUCT AND/OR C2-C4 OLEFINS

摘要

A process for making a distillate product and one or more C2-C4 olefins from a FCC feedstock containing a cellulosic material and a hydrocarbon co-feed is provided.

主权项

1. A process for making a distillate product and one or more C2-C4 olefins comprising:
a) contacting a FCC feedstock with a FCC catalyst at a temperature of at least 400° C. in a main reactor to produce a distillate product and a spent FCC catalyst, wherein the FCC feedstock comprises a solid cellulosic material and a hydrocarbon co-feed, said solid cellulosic material is supplied to the main reactor at a location upstream of the location where the hydrocarbon co-feed is supplied to the main reactor wherein the solid cellulosic material undergoes in-situ pyrolysis in the main reactor; b) separating at least a portion of the distillate product from the spent FCC catalyst; c) regenerating the spent FCC catalyst to produce a regenerated FCC catalyst; d) contacting an intermediate reactor feedstock with at least a portion of the regenerated FCC catalyst at a temperature of at least 500° C. in an intermediate reactor to produce one or more C2-C4 olefins and a used regenerated FCC catalyst; e) separating at least a portion of the one or more C2-C4 olefins from the used regenerated catalyst; and f) providing at least a portion of the used regenerated FCC catalyst as FCC catalyst in step a).
