A process for producing benzene and xylenes comprising introducing hydrocarbon liquid stream to hydroprocessor to yield first gas stream and hydrocarbon product (C5+); optionally introducing hydrocarbon product to first aromatics separating unit to produce saturated hydrocarbons (C5+) and first aromatics stream (C6+); 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 C6+ 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 C6 aromatics (benzene), C7 aromatics (toluene), C8 aromatics (xylenesðylbenzene), C9 aromatics, C10 aromatics, and C11+ aromatics; introducing C7 aromatics, C9 aromatics, C10 aromatics, or combinations thereof to disproportionation and transalkylation unit to yield third aromatics stream (benzene and xylenes); and conveying C11+ aromatics to hydroprocessor.
A process for producing benzene and xylenes comprising:
