Reforming-hydroforming system

Claim 1

THE METHOD OF CONVERTING A NAPHTHA IN HIGH YIELDS TO MOTOR FUEL OF ABOUT 100 OCTANE NUMBER (CFR-R), WHICH METHOD COMPRISES FRACTIONATING SAID NAPHTHA TO FORM A LIGHT FRACTION HAVING AN END POINT OF APPROXIMATELY 200* F. AND A HEAVY FRACTION BOILING IN THE RANGE OF ABOUT 200 TO 400* F., REFORMING THE LIGHT FRACTION BY DEHYDROGENATION AND AROMATIZING OF THE LIGHT FRACTION BY CONTACT WITH ALKALIZED CHROMIA-ON-ALUMINA CATALYST AT ABOUT 975 TO 1125* F. UNDR A PRESSURE IN THE RANGE OF ATOMSPHERIC TO 200 P.S.I.G. WITH A SPACE VELOCITY IN THE RANGE OF .1 TO 10 VOLUMES OF LIGHT NAPHTHA PER HOUR PER VOLUME OF CATALYST, REMOVING NORMALLY GASEOUS HYDROCARBONS FROM THE REFORMED LIGHT FRACTION TO OBTAIN DEBUTANIZED REFORMATE, HYDROFROMING THE HEAVY FRACTION BY CONTACT IN AT LEAST 3 HEATING-REACTION STAGES WITH PLATINUM-ON-ALUMINA CATALYST AT ABOUT 850 TO 1000* F. AND 100 TO 400 P.S.I. IN THE PRESENCE OF RECYCLED HYDROGEN TO PRODUCE HYDROFORMED HEAVY NAPHTHA, REMOVING NORMALLY GASEOUS HYDROCARBONS FROM THE HYDROFORMED HEAVY MAPHTHA, FRACTIONATING THE REMAINING HYDROFORMED HEAVY MAPHTHA TO REMOVE FROM HEAVY HYDROFORMATE COMPONENETS BOILING BELOW ABOUT 200* F., INTRODUCING SAID LAST NAMED COMPONENTS TOGETHER WITH SAID LIGH FRACTION TO THE LIGH FRACTION CONTRACTING STEP FOR REFORMING WITH SAID ALKALIZED CHROMIA-ON-ALUMINA CATALYST AND COMBINING SAID DEBUTANIZED REFORMATE WITH SAID HEAVY HYDROFORMATE TO OBTAIN A FULL BOILING RANGE GASOLINE OF AT LEAST ABOUT 100 CFR-R OCTANE NUMBER ON AN UNLEADED BASIS

Claim 2

THE METHOD OF CONVERTING A NAPHTHA IN HIGH YIELDS TO MOTOR FUEL OF ABOUT 100 OCTANE NUMBER (CFR-R), WHICH METHOD COMPRISES FRACTIONATING SAID NAPHTHA TO FORM A LIGHT FRACTION HAVING AN END POINT OF APPROXIMATELY 200* F. AND A HEAVY FRACTION BOILING IN THE RANGE OF ABOUT 200 TO 400* F., REFORMING THE LIGHT FRACTION BY DEHYDROGENATION AND AROMATIZING OF THE LIGHT FRACTION BY CONTACT WITH ALKALIZED CHROMIA-ON-ALUMINA CATALYST AT ABOUT 975 TO 1125* F. UNDR A PRESSURE IN THE RANGE OF ATOMSPHERIC TO 200 P.S.I.G. WITH A SPACE VELOCITY IN THE RANGE OF .1 TO 10 VOLUMES OF LIGHT NAPHTHA PER HOUR PER VOLUME OF CATALYST, REMOVING NORMALLY GASEOUS HYDROCARBONS FROM THE REFORMED LIGHT FRACTION TO OBTAIN DEBUTANIZED REFORMATE, HYDROFROMING THE HEAVY FRACTION BY CONTACT IN AT LEAST 3 HEATING-REACTION STAGES WITH PLATINUM-ON-ALUMINA CATALYST AT ABOUT 850 TO 1000* F. AND 100 TO 400 P.S.I. IN THE PRESENCE OF RECYCLED HYDROGEN TO PRODUCE HYDROFORMED HEAVY NAPHTHA, REMOVING NORMALLY GASEOUS HYDROCARBONS FROM THE HYDROFORMED HEAVY MAPHTHA, FRACTIONATING THE REMAINING HYDROFORMED HEAVY MAPHTHA TO REMOVE FROM HEAVY HYDROFORMATE COMPONENETS BOILING BELOW ABOUT 200* F., INTRODUCING SAID LAST NAMED COMPONENTS TOGETHER WITH SAID LIGH FRACTION TO THE LIGH FRACTION CONTRACTING STEP FOR REFORMING WITH SAID ALKALIZED CHROMIA-ON-ALUMINA CATALYST AND COMBINING SAID DEBUTANIZED REFORMATE WITH SAID HEAVY HYDROFORMATE TO OBTAIN A FULL BOILING RANGE GASOLINE OF AT LEAST ABOUT 100 CFR-R OCTANE NUMBER ON AN UNLEADED BASIS
