Conversion of waste plastic through pyrolysis to high value products like benzene and xylenes

Abstract

A process for producing benzene and xylenes comprising introducing hydrocarbon liquid stream to hydroprocessor to yield first gas stream and hydrocarbon product (C+); optionally introducing hydrocarbon product to first aromatics separating unit to produce saturated hydrocarbons (C+) and first aromatics stream (C+); feeding hydrocarbon product and/or saturated hydrocarbons to reformer to produce reformer product, second gas stream, and hydrogen stream; introducing reformer product to second aromatics separating unit to produce a non-aromatics recycle stream and second aromatics stream comprising C+ aromatics; recycling non-aromatics recycle stream to reformer; introducing first aromatics stream and/or second aromatics stream to third aromatics separating unit to produce first Caromatics (benzene), Caromatics (toluene), Caromatics (xylenes&ethylbenzene), Caromatics, Caromatics, and C+ aromatics; introducing Caromatics, Caromatics, Caromatics, or combinations thereof to disproportionation and transalkylation unit to yield third aromatics stream (benzene and xylenes); and conveying C+ aromatics to hydroprocessor.
