ABSTRACT:
Hydrocarbons are alkylated using slowly moving cylindrical beds of solid catalyst in a process featuring a cooling zone within the reaction zone and a moving bed catalyst regeneration zone. The catalyst passes downward through both zones, which may be stacked upon one another. The reaction zone is operated at liquid-phase conditions, and the catalyst is periodically subjected to a regeneration procedure employing a hydrogen-containing stream. Direct heat exchange within the reaction zone removes the heat of the reaction.
