ABSTRACT:
Hydrocarbons are alkylated in a fluidized riser-reactor using a solid catalyst which is regenerated within the process by contact with hydrogen. The alkylation and regeneration steps are separated to prevent the admixture of hydrogen and any olefins present in the process. Two separate modes of regeneration are performed simultaneously: a mild liquid-phase washing and a vapor-phase hot hydrogen stripping operation.
