Abstract

A naphtha is catalytically reformed by contacting with a platinum catalyst in the presence of hydrogen under a pressure of 100-300 p.s.i.g. to cause aromatization, separating a heavy fraction boiling above 230 DEG F. from the liquid reformate and catalytically reforming this heavy fraction in the presence of hydrogen and a platinum or molybdena catalyst under a pressure of 300-800 p.s.i.g. to cause dealkylation. The feed is preferably a C5+ naphtha boiling below 480 DEG F. and is treated in the first stage with a fixed or fluidized bed of catalyst containing 0.2-2% of platinum on alcoholate alumina, activated alumina, silica gel, zinc alumina or zinc alumina spinel, and containing if desired zinc, calcium oxide, ceria or potassia. Suitable conditions are 800-1000 DEG F. with 2000-6000 SCF of added hydrogen per barrel of feed. The liquid reformate is separated from gaseous effluent which may be recycled or used in the second reforming. The heavy reformate led to the second reforming preferably boils between 230 DEG and 400 DEG F. and may be mixed with fresh naphtha if desired; the light reformate is removed as product. Conditions in the second reforming may be 880-1100 DEG F., with 2000-6000 SCF of added hydrogen per barrel. In this stage hydrogen is consumed and light hydrocarbons formed and the normally gaseous effluent cannot be used as recycle gas without at least partial removal of light hydrocarbons. The product may be fractionated, if desired in the same fractionator as the reformate from the first stage, product boiling below 250 DEG F. being removed as product and higher boiling material being recycled to the second stage.
