Combination process for upgrading reduced crude

Patent ·
OSTI ID:5212526
A process is described for the conversion of a feed containing high boiling hydrocarbons and having Conradson carbon producing materials, which process is carried out in a hydrocarbon conversion system comprising a riser conversion zone and a regeneration zone. The process consists of: A. contacting the feed with a fluid hydrocarbon conversion catalyst in the riser conversion zone in the presence of water and a first CO-rich flue gas to form a gasiform effluent containing lower molecule weight hydrocarbons and coke on the catalyst; B. separating the gasiform effluent from the coked catalyst; C. regenerating the coked catalyst in the regeneration zone consisting of a first regeneration stage and a second regeneration stage; D. sending the regenerated catalyst to the riser conversion zone; E. separating the gasiform effluent from and riser conversion zone into a C/sub 2/-minus gaseous product, a C/sub 3/-plus hydrocarbon product and a water-containing condensation product and recovering separately therefrom hydrogen; F. purifying the hydrogen to form purified hydrogen for use in producing a synthesis gas; and G. recovering useful hydrocarbon products from the C/sub 3/-plus hydrocarbon product.
