Hydrocarbonaceous feedstocks admixed with a flow-through catalyst and hydrogen are hydroprocessed in a hydroprocessing reactor containing a captive hydroprocessing catalyst. The flow-through catalyst is continually withdrawn with the hydroprocessed feed from the hydroprocessing reactor. The flow-through catalyst may be an FCC, hydrocracking, isomerization or ring-opening catalyst. In a preferred embodiment, the captive hydroprocessing catalyst contains Co, Ni and/or Mo on an alumina base and the flow-through catalyst is an FCC zeolitic catalyst which is withdrawn with the hydroprocessed feed from the hydroprocessing reactor and then sent to an FCC unit.

[ What is claimed is:] [1.] In a process for hydroprocessing a hydrocarbon feed which has not been previously hydroprocessed by contact with hydrogen in a hydroprocessing reactor, the improvement which comprises:(a) introducing into the hydroprocessing reactor the hydrocarbon feed and a flow-through catalyst which has acidic sites and enhances the performance of the hydroprocessing catalyst by promoting hydrocracking, or isomerization, or ring opening, or combinations thereof of the feed;(b) hydrotreating the hydrocarbon feed in the hydroprocessing reactor containing a captive hydroprocessing catalyst under hydroprocessing conditions which do not materially deactivate the flow-through catalyst;(c) recovering a mixture of hydroprocessed feed and the flow-through catalyst from the hydroprocessing reactor; and(d) delivering and introducing the mixture of hydroprocessed feed and the flow-through catalyst from the hydroprocessing reactor to an FCC system.
