<p>A process for the alkylation of benzene contained in a mixed refinery stream is disclosed wherein the refinery stream (2) is first subjected to hydrogenation (14) of higher olefins prior to alkylation (12) to the benzene with selected types and quantities of lower olefins (1). Streams containing sulfur compounds may be pretreated by hydrodesulfurization. All of the process steps are advantageously carried out in distillation column reactors (10) to take advantage of that mode operation.</p> |
