摘要: A catalytic reforming process uses a riser reactor with multiple catalyst injection points to obtain high aromatics yields from a naphtha feedstock. Product from the riser reactor typically is discharged into a fluidized-reforming reactor, in which the reforming reaction is completed and catalyst is separated from hydrogen and hydrocarbons. Hydrocarbons from the reactor are separated to recover an aromatized product. Catalyst is regenerated to remove coke and reduced for reuse in the reforming process.

摘要: 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.
