Abstract
An integrated hydrocarbon conversion process is described. The process includes contacting a heavy hydrocarbon feedstock with a hydrocarbon cracking catalyst in a fluidized reactor zone to produce light olefins to form a fluid catalytic cracker (FCC) effluent stream comprising a range of hydrocarbons. The FCC effluent stream is separated to form at least a stream rich in C4 hydrocarbons which comprises isobutane and 1-butene. The stream rich in C4 hydrocarbons is introduced into an alkylation reaction zone where the isobutane and the 1-butene are alkylated to form a reaction product mixture comprising dimethylhexanes and C9+ hydrocarbons. The reaction product mixture is dehydrocyclized to form a stream rich in xylenes.
