ABSTRACT:
A process for the catalytic reforming of a hydrocarbonaceous feedstock, preferably to produce high quality gasoline boiling range products, is disclosed. Relatively impure hydrogen is separated from the reforming zone effluent, compressed, and recontacted with at least a portion of the liquid reformate product to provide relatively pure hydrogen, a portion of which is recycled to the reforming zone. The balance is further compressed and recontacted with at least a portion of the liquid reformate product to provide an improved recovery of normally gaseous hydrocarbons as well as an improved recovery of purified hydrogen at a pressure suitable for use in the relatively high pressure hydrotreating of sulfur-containing feedstocks.
