ABSTRACT:
A process is disclosed for reforming a hydrocarbon in a multi-stage endothermic reforming series of reforming reactors where the hydrocarbon is passed through a series of reforming reactors to form a reformate with substantial reduction in polynuclear aromatic compounds. An adsorption zone comprising an adsorbent selective for adsorption of polynuclear aromatics is situated intermediate the series of reactors. The adsorbent is followed by an intermediate heating means to insure that the temperature of the hydrocarbon product entering the next reforming stage is at a temperature sufficient that the hydrocarbon product will have a temperature of at least 750.degree. F. when egressing from the next respective reforming zone. The contemplated reforming feeds are C.sub.6 to C.sub.10 naphthas having a boiling point of 100.degree. F. to 400.degree. F. while the ultimate reformate is used as a blending agent for gasolines to increase the octane value of the respective gasoline.
