Abstract

A process for producing cumene comprising converting plastics to hydrocarbon liquid and pyrolysis gas; feeding hydrocarbon liquid to hydroprocessor to yield hydrocarbon product and first gas stream; feeding hydrocarbon product to reforming unit to produce reforming product, second gas stream, and hydrogen; separating reforming product into non-aromatics recycle stream and second aromatics stream (C+ aromatics); recycling non-aromatics recycle stream to reforming unit; separating second aromatics stream into benzene, C, C, C, C, and C+ aromatics; contacting C, C, and/or Caromatics with a disproportionation&transalkylation catalyst/H2 to yield benzene&xylenes; conveying C+ aromatics to hydroprocessor; introducing pyrolysis gas, first and/or second gas stream to first separator to produce first propylene stream, first C&Cunsaturated stream, and saturated gas (Hand Csaturated hydrocarbons); introducing first C&Cunsaturated stream to metathesis reactor to produce second propylene stream; and feeding benzene, and first and/or second propylene stream to alkylation unit to produce cumene.
