    摘要： This invention relates to a process for cracking hydrocarbon feedstock containing resid comprising: (a) heating a hydrocarbon feedstock containing resid; (b) adding molecular hydrogen to said heated feedstock to form a mixture stream; (c) adding a catalyst containing metal-sulfide particles to said heated feedstock and/or said mixture stream; (d) reacting said mixture in a catalytic hydrovisbreaking reactor under conditions of temperature, pressure and residence time sufficient to catalytically hydrovisbreak at least a portion of said resid into hydrovisbroken hydrocarbon components; (e) passing said reacted mixture stream into a high pressure separator and separating hydrogen from said reacted mixture; (f) passing said reacted mixture through a knockout drum to remove catalyst and unreacted or uncracked resid as a bottoms stream; and (g) passing said catalytically hydrovisbroken hydrocarbon components into a steam cracking furnace and thermally cracking said hydrocarbon components to form light olefins, alternately the knockout drum of step (f) is integrated into the steam cracking furnace of step (g).
