Abstract:
1. A hydrocarbon upgrading process comprising: (a) treating a hydrocarbon feed in at least one of a steam cracker, catalytic cracker, coker, hydrocracker, and reformer under suitable conditions to produce a first stream comprising olefinic and aromatic hydrocarbons; (b) recovering from said first stream a second stream composed mainly of C (c) contacting at least part of the second stream with a catalyst in the absence of added hydrogen under reaction conditions including a temperature of about 450° C. to about 700° C. effective to dealkylate, transalkylate, crack and aromatize components of said second stream to produce a third stream having an increased benzene and/or toluene content compared with said second stream and a C (d) recovering C (e) separating a fourth stream comprising toluene from said third stream; and (f) methylating at least part of the fourth stream with a methylating agent to produce a xylene-enriched C
