Abstract
A process is disclosed for reforming two hydrocarbon feedstocks by contacting one feedstock and hydrogen with a reforming catalyst in a first reforming zone at reforming conditions including a relatively high reforming pressure; separating a hydrogen-rich gas and first hydrocarbon product from the effluent from the first zone at a pressure below the first reforming pressure; recycling a first portion of the hydrogen-rich gas to provide hydrogen for the first reforming zone; contacting the other feedstock and a second portion of the hydrogen-rich gas with a second reforming catalyst in a second reforming zone at reforming conditions including a pressure lower than the first reforming pressure, with all of the hydrogen gas introduced into the second reforming zone being obtained solely from the first reforming zone effluent; and recovering a second hydrocarbon product from the effluent from the second reforming zone. The process eliminates a hydrogen recycle compressor for the second reforming zone and operates without compressing hydrogen passed from the first reforming zone to the second reforming zone.
