Abstract:
A process for upgrading hydrocarbons comprising the steps of:a) heating a hydrocarbon feedstock comprising CPD, DCPD, C.sub.5 diolefins, benzene, toluene, and xylene in a heating zone, to dimerize CPD to DCPD, thereby forming a first effluent;b) separating said first effluent into a C.sub.6 + stream and a C.sub.5 diolefin stream comprising C.sub.5 diolefins;c) separating said C.sub.6 + stream into a C.sub.6 -C.sub.9 stream and a C.sub.10 + stream;d) separating said C.sub.10 + stream into a fuel oil stream and a DCPD stream comprising DCPD; ande) hydrotreating said C.sub.6 -C.sub.9 stream to thereby form a BTX stream comprising benzene, toluene and xylene.
