ABSTRACT:
A process for producing gasoline blending components from a heavy hydrocarbon composition comprising alkyl aromatics by transalkylation of said alkyl aromatics with benzene is provided. In a preferred embodiment, the process comprises (a) feeding said heavy hydrocarbon composition comprising alkyl aromatics and said benzene as feed to a cracking unit; and (b) contacting said alkyl aromatics and said benzene with cracking catalyst at catalytic cracking conditions of elevated temperature and pressure to produce transalklyation products. Also, provided is a process, for producing gasoline blending components from the jet aromatics content of jet fuel and reducing the benzene content of a benzene-rich light gasoline stream, said process comprising operating a catalytic cracker at conventional catalytic cracking conditions and reacting in said catalytic cracking reactor said aromatic jet fuel with said benzene-rich light gasoline stream to convert at least a portion of said benzene-rich gasoline and at least a portion of said jet aromatics to toluene and xylenes. The catalytic cracker can be a fluid catalytic cracker, moving bed catalytic cracker and fixed bed catalytic cracker.
