Method and Apparatus for Converting Hydrocarbons Into Olefins Using Hydroprocessing and Thermal Pyrolysis

摘要

An apparatus and method are provided for processing hydrocarbon feeds. The method may contact hydrogen (H2) and a hydrocarbon feed containing ≧10 wt % resid in the hydrocarbon feed with a catalyst to form a hydroprocessed product. Then, a pyrolysis feed derived from the hydroprocessed product is exposed at high-severity thermal pyrolysis operating conditions to produce a reactor product that comprises ethylene and acetylene. Further, at least a portion of the hydrogen (H2) may be separated from the reactor product, wherein the hydrogen (H2) contacting the catalyst includes at least a portion of the separated hydrogen (H2).

1. A method for processing hydrocarbons comprising:
contacting hydrogen (H2) and a hydrocarbon feed containing ≧10.0 wt % resid in the hydrocarbon feed with a catalyst to form a hydroprocessed product; exposing a pyrolysis feed derived from the hydroprocessed product at high-severity thermal pyrolysis operating conditions to produce a reactor product that comprises hydrogen, ethylene and acetylene; and separating at least a portion of the hydrogen (H2) from the reactor product, wherein the hydrogen (H2) contacting the catalyst comprises at least a portion of the separated hydrogen (H2).
