A PROCESS FOR PRODUCING GASEOUS PRODUCTS CONTAINING AT LEAST 70 VOL. PERCENT HYDROGEN AND PRODUCT COKE HAVING A PARTICLE SIZE DIAMETER IN THE RANGE OF ABOUT 200 TO 500 MICRONS WHICH COMPRISES THE STEPS OF CONTACTING A HEAVY HYDROCARBON OIL HAVING A CONRADSON CARBON RESIDUE CONTENT OF AT LEAST 10% WITH AN ADDED NORMALLY GASEOUS HYDROCARBON IN A REACTION ZONE AT A TEMPERATURE IN THE RANGE OF 1700*F. TO 2500*F., THE RATIO BY WEIGHT OF THE HEAVY HYDROCARBON OIL TO THE HYDROCARBON GAS UTILIZED BEING IN THE RANGE OF 1/5 TO 10/1 OVER FLUIDIZED COKE PARTICLES HAVING A DIAMETER IN THE RANGE OF ABOUT 150 TO 400 MICRONS; MAINTAINING THE RESULTANT REACTION FOR A PERIOD OF TIME SUFFICIENT TO OBTAIN THE DESIRED REACTION; SEPARATING THE GASEOUS PRODUCTS CONTAINING EVOLVED HYDROGEN FROM THE COKE PARTICLES; BURNING A PORTION OF THE COKE PARTICLES IN A SEPARATE BURNING ZONE TO INCREASE THE TEMPERATURE THEREOF; SEPARATING GASEOUS COMBUSTION PRODUCTS FROM THE HEATED COKE, RETURNING A PORTION OF THE HEATED COKE PARTICLES TO THE REACTION ZONE AND WITHDRAWING PRODUCT COKE.
