A PROCESS WHICH COMPRISES COKING A HYDROCARBON OIL IN THE PRESENCE OF FLUIDIZED PARTICLES OF A HIGHER OXIDE OF IRON AT A TEMPERATURE BETWEEN ABOUT 700* F. AND ABOUT 1200* F. FORMING A COKER DISTILLATE AND COKE-LADEN HIGHER IRON OXIDE PARTICLES, SEPARATING SAID COKER DISTILLATE FROM SAID PARTICLES, SUBJECTING SAID COKE-LADEN PARTICLES TO TREATMENT AT A TEMPERATURE BETWEEN ABOUT 1000* F. AND ABOUT 1500* F. WHILE IN A FLUIDIZED STATE IN A GAS CONTAINING OXYGEN TO EFFECT THE COMBUSTION OF SAID COKE THEREFROM AND THE DIRECT HEATING AND THE CARBON REDUCTION OF SAID HIGHER IRON OXIDE FORMING GASES CONTAINING CARBON MONOXIDE AND COKE-FREE REDUCED IRON-CONTAINING PARTICLES, FLUIDIZING THE PARTICLES THUS OBTAINED IN STEAM AT A TEMPERATURE BETWEEN ABOUT 800* F. AND ABOUT 1500* F. TO FORM HYDROGEN AND THEREBY REFORMING THE HIGHER IRON OXIDE, SEPARATING HYDROGEN THUS PRODUCED AND RECIRCULATING THE HIGHER IRON OXIDE TO CONTACT FURTHER QUANTITIES OF SAID HYDROCARBON OIL.
