Abstract:
1. An apparatus for alkylating benzene with ethylene comprising: a fluid catalytic cracking reactor for contacting cracking catalyst with a hydrocarbon feed stream to crack the hydrocarbon feed to cracked products having lower molecular weight and deposit coke on the cracking catalyst to provide coked cracking catalyst; a regenerator for combusting coke from said coked cracking catalyst by contact with oxygen; a separator in communication with said fluid catalytic cracking reactor for separating C a reforming reactor for contacting a naphtha stream with reforming catalyst to produce a reformate stream; and an alkylation reactor in communication with said separator and said reforming reactor for alkylating benzene in said reformate stream with ethylene in said dilute ethylene stream over a fixed bed of alkylation catalyst to heavier alkyl benzene hydrocarbons, wherein no fractionation column is in communication between said separator and said alkylation reactor.
