A process for producing alkyl aromatics using a transalkylation reaction
zone and an alkylation reaction zone is disclosed. The transalkylation
reaction zone effluent passes to the alkylation reaction zone where
aromatics in the transalkylation reaction zone effluent are alkylated to
the desired alkyl aromatics. This process decreases the capital and
operating costs of recycling the aromatics in the transalkylation reaction
zone effluent. This process is well suited for solid transalkylation and
alkylation catalysts. Ethylbenzene and cumene may be produced by this
process.
