Combined hydrocarbon conversionhydrocarbon synthesis process

Claim 1

A PROCESS FOR PRODUCING NORMALLY LIQUID HYDROCARBONS BOILING IN THE GASOLINE RANGE COMPRISING CRACKING A SUITABLE HYDROCARBON FEED AT A TEMPERATURE IN THE RANGE OF 900 TO 1100*F. AND A PRESSURE BETWEEN 1 AND 25 ATMOSPHERES ABSOLUTE IN CONTACT WITH A CRACKING CATALYST SO AS TO PRODUCE HYDROCARBONS BOILING IN THE GASOLINE RANGE WITH CONCOMITANT DEPOSITION OF CARBON ON SAID CATALYST IN AN AMOUNT IN THE RANGE OF 1 TO 10 PER CENT BY WEIGHT THEREOF; CONVERTING SAID CARBON TO CO BY CONTCTING SAME AT A TEMPERATURE IN THE RANGE OF 1100 TO 1800*F. AND A PRESSURE UP TO 25 ATMOSPHERES ABSOLUTE WITH A GASEOUS MIXTURE CONSISTING ESSENTIALLY OF STEAM AND OXYGEN IN A RATIO IN THE RANGE OF 9:1 TO 1:4 BY VOLUME WITH CONCOMITANT PRODUCTION OF H2 AND A MINIMUM AMOUNT OF CO2; CONCENTRATING THE CO AND H2 IN THE REGENERATION EFFLUENT BY REMOVAL OF CO2 AND H2O THEREFROM AND CONTACTING THE RESULTING MIXTURE OF CO AND H2 WITH A FISCHER-TROPSCH CATALYST AT A TEMPERATURE IN THE RANGE OF 340 TO 700*F. AND AT PRESSURE IN THE RANGE OF 1 TO 20 ATMOSPHERES ABSOLUTE SO AS TO SYNTHESIZE HYDROCARBONS BOILING IN THE GASOLINE RANGE TOGETHER WITH HEAVIER HYDROCARBONS; SEPARATING THE SYNTHESIS EFFLUENT INTO A GASOLINE FRACTION AND A HEAVIER FRACTION; RECYCLING THE HEAVIER FRACTION TO THE CRACKING STEP; AND BLENDING GASOLINE HYDROCARBONS FROM THE SYNTHESIS AND CRACKING STEPS.
