Heavy oil conversion with low coke formation

Claim 1

A PROCESS FOR THE CONVERSION OF A HEAVY HYDROCARBON OIL HAVING A RAMSBOTTOM CARBON VALUE OF AT LEAST ABOUT 10, WHICH COMPRISES INJECTING SAID OIL INTO A RAPIDLY MOVING GASEOUS STREAM CONTAINING HYDROGEN AND HAVING A VELOCITY OF AT LEAST ABOUT 10 FEET PER SECOND AND CONVEYING DISPERSED HEATED CARRIER PARTICLES FROM A REGENERATION ZONE HEREINAFTER SPECIFIED IN SUBSTANTIALLY THE SAME DIRECTION AS THAT OF SAID GASEOUS STREAM TO YIELD A MIXTURE HAVING A HYDROGEN PARTIAL PRESSURE OF AT LEAST ABOUT 35 P. S. I. AND A TEMPERATURE IN THE RANGE OF ABOUT 1200 TO 1600*F., MAINTAINING SAID MIXTURE AT TEMPERATURES IN SAID RANGE FOR NOT MORE THAN ABOUT 3 SECONDS, SEPARATING SAID CARRIER PARTICLES FROM SAID MIXTURE, RECOVERING CONVERTED HYDROCARBONS FROM THE REMAINING GASEOUS PORTION OF SAID MIXTURE, TREATING THE SEPARATED CARRIER PARTICLES IN THE AFORESAID REGENERATION ZONE WITH OXYGEN AND STREAM AT A TEMPERATURE ABOVE ABOUT 1600*F. TO REHEAT SAID SEPARATED CARRIER PARTICLES AND TO GASIFY CARBONACEOUS MATERIAL DEPOSITED THEREON BY SAID OIL THEREBY PRODUCING HYDROGEN-CONTAINING GASES, RECOVERING FROM SAID GASES SAID GASEOUS STREAM CONTAINING HYDROGEN, AND AGAIN CONVEYING THE REHEATED CARRIER PARTICLES FROM THE AFORESAID REGENERATION ZONE IN SAID GASEOUS STREAM CONTAINING HYDROGEN AS AFORESAID.
