Hydrocarbon feedstocks containing C 5 olefins, C 5 diolefins, CPD, DCPD, and aromatics are CPD, DCPD, C 5 diolefins, benzene, toluene and xyl in the heating zone 100 so that the CPD dimerizes to DCPD. The hydrocarbon feedstock 102 containing the lene is heated to form a first effluent 104; A first effluent is separated into a C 6 + stream 110 and a C 5 diolefin stream 108; The C 6 + stream is separated into a C 6 -C 9 stream 114 and a C 10 + stream; The C 10 + stream is separated into a fuel oil stream 134 and a DCPD stream 132; The C 6 -C 9 stream is subjected to hydrogenation to form a BTX stream.n n n n Hydrocarbon, DCPD, Hydrogenation, Hydrogen Desulfurization, BTX |
