Abstract: This invention relates to a process and system for cracking hydrocarbon feedstock containing vacuum resid comprising: (a) subjecting a vacuum resid to a first thermal conversion in a thermal conversion reactor (such as delayed coker, fluid coker, Flexicoker™, visbreaker and catalytic hydrovisbreaker) where at least 30 wt % of the vacuum resid is converted to material boiling below 1050° F. (566° C.); (b) introducing said thermally converted resid to a vapor/liquid separator, said separator being integrated into a steam cracking furnace, to form a vapor phase and liquid phase; (c) passing said vapor phase to the radiant furnace in said steam cracking furnace; and (d) recovering at least 30 wt % olefins from the material exiting the radiant furnace (based upon the weight of the total hydrocarbon material exiting the radiant furnace).

Abstract: A method and system for converting hydrocarbons into C2+ unsaturates is described. The method includes providing a structural member upstream of a reaction zone having a surface of a catalytic material, wherein the catalytic material is rendered catalytically active to promote the reaction of coke and/or coke precursors with hydrogen (H2) and/or an oxidant. Then, the method involves exposing a hydrocarbon stream to the catalytic material, wherein the hydrocarbon stream comprising coke and/or coke precursors react in the presence of the catalytic material to convert at least a portion of the coke and/or coke precursors to vapor products. Finally, the hydrocarbons in the hydrocarbon stream containing vapor products and hydrocarbons are converted in the reaction zone to produce a reactor product having C2+ unsaturates.
