Processing scheme and arrangement for increasing the relative yield of light olefins involves integration of the cracking a heavy hydrocarbon feedstock to produce an effluent comprising a range of hydrocarbon products including C<SUB>4</SUB>-C<SUB>7 </SUB>olefins and the subsequent cracking at least a portion of the C<SUB>4</SUB>-C<SUB>7 </SUB>olefins to produce additional light olefins. |
