Abstract
A process for the catalytic reforming of a hydrocarbonaceous feedstock at reforming conditions including a pressure of from about 50 to about 250 psig. is disclosed. A portion of the hydrogen-rich vapor phase recovered from the reforming zone effluent at a relatively low pressure is compressed and recycled to the reforming zone without further purification. The balance of said hydrogen-rich vapor phase, or the net hydrogen, is compressed to a relatively high pressure and recontacted with at least a portion of the liquid hydrocarbon phase recovered from said low pressure separation to effect a further purification of said net hydrogen and to maximize the recovery of C.sub.3 -C.sub.6 + material in the liquid phase.
