Patent attributes
A process for catalytically reforming a gasoline boiling range hydrocarbonaceous feedstock in the presence of hydrogen involving the following steps:(a) reforming at least 5 vol % and at most 50 vol % of the feedstock in a first reforming unit having a fixed bed of catalyst particles;(b) passing the effluent stream of the first reforming unit to a separation zone having a separator and a stabilizer to produce a hydrogen-rich gaseous stream, a C4− hydrocarbon stream and a first reformate;(c) reforming the remainder of the feedstock and at least part of the first reformate in a second reforming unit having one or more serially connected reaction zones, each having 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 having a separator and a stabilizer to produce a hydrogen-rich gaseous stream, a C4− hydrocarbon stream and a second reformate.
