ABSTRACT:
A process for producing alkylaromatics using a multibed alkylation reaction zone is disclosed. The alkylation reaction zone effluent is divided into three portions, the first being recirculated to the inlet of the reaction zone, the second being cooled and recirculated to one or more other beds in the reaction zone, and the third being passed to a product recovery zone where the alkylaromatic is recovered. This process insures that all of the catalyst beds operate in an optimum temperature range. This in turn insures that byproduct formation is minimized and catalyst life is maximized. Ethylbenzene and cumene may be produced by this process.
