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) feeding said second stream and a methylating agent to a reaction zone containing a catalyst under reaction conditions including a temperature of about 450° C. to about 700° C., such that aromatics components in the second stream undergo dealkylation, transalkylation and/or methylation and aliphatic components undergo cracking and aromatization to produce a third stream having an increased xylene content compared with said second stream and a C (d) recovering the C (e) recovering at least para-xylene from at least part of said third stream.
