Low pressure reforming process utilizing high purity hydrogen

Claim 1

A PROCESS FOR THE REFORMING OF A GASOLINE BOILING RANGE HYDROCARBON CHARGE STOCK CONTAINING PARAFFINS AND NAPHTHENES WHICH COMPRISES: INTRODUCING SAID HYDROCARBON CHARGE STOCK AND A SUBSTANTIALLY PURE HYDROGEN STREAM INTO A REFORMING REACTION ZONE CONTAINING A PLATINUM GROUP METAL REFORMING CATALYST, SAID ZONE BEING MAINTAINED AT REFORMING REACTION CONDITIONS INCLUDING A TEMPERATURE OF ABOUT 800*F. TO ABOUT 1050*F., A HYDROGEN TO HYDROCARBON MOLE RATIO OF ABOUT 3 TO ABOUT 20, AND A LHSV OF ABOUT 0.5 TO ABOUT 5; AND MAINTAINING A REACTOR PRESSURE SELECTED WITHIN THE RANGE BOUDED BY THE EQUATIONS Y=0.833X-14 AND Y=X-150 WHERE X IS THE TEMPERATURE IN *F. OF THE 95% POINT OF THE CHARGE STOCK ON AN ENGLER DISTILLATION CURVE BEING LIMITED TO A MAXIMUM OF ABOUT 400* F. AND Y IS THE PRESSURE IN P.S.I.G. BEING LIMITED FROM 50 TO 300 P.S.I.G., SAID REFORMING CONDITIONS AD PRESSURE BEING SELECTED TO PRODUCE A REFORMATE HAVING AN F-1 CLEAR OCTANE NUMBER GREATER THAN ABOUT 90.
