Patent ID: 7419583

Claim:
A process for catalytically reforming a gasoline boiling range hydrocarbonaceous feedstock in the presence of hydrogen comprising the following steps: (a) reforming a first feedstock, which is at least 5 vol % and at most 50 vol % of the gasoline boiling range hydrocarbonaceous feedstock to said process, in a first reforming unit comprising a fixed bed of catalyst particles; (b) passing the effluent stream of the first reforming unit to a separation zone comprising a separator and a stabilizer to produce a hydrogen-rich gaseous stream, a C4− hydrocarbon stream and a first reformate; (c) reforming a second feedstock, which is at least 50 vol % of the gasoline boiling range hydrocarbonaceous feedstock to said process, and at least part of the first reformate from step (b) in a second reforming unit comprising one or more serially connected reaction zones, each comprising a moving catalyst bed, which are operated in a continuously catalyst regeneration mode; and (d) passing the effluent stream of the second reforming unit to a separation zone comprising a separator and a stabilizer to produce a hydrogen-rich gaseous stream, a C4− hydrocarbon stream and a second reformate.
