Claim 1

A PROCESS FOR THE CONVERSION OF HEAVY HYDROCARBON OILS, WHICH COMPRISES INJECTING A MULTIPLICITY OF STREAMS OF SAID HEAVY OIL INTO AN ENLARGED CIRCULAR COKING VESSEL CONTAINING A BODY OF FINELY DIVIDED SOLIDS HAVING A PSEUDOLIQUID LEVEL AT THE UPPER PORTION OF SAID VESSEL, CIRCULATING SAID SOLIDS TO AN EXTERNAL HEATING ZONE, CIRCULATING HEATED SOLIDS FROM SAID HEATING ZONE TO SAID COKING VESSEL, TANFENTIALLY INJECTING SAID HEATED SOLIDS INTO AN ANNULUS IN THE UPPER PORTION OF SAID VESSEL ABOVE THE LEVEL OF SAID BODY OF SOLIDS TO MAINTAIN SAID VESSEL AT A COKING TEMPERATURE BETWEEN 900* AND 1200* F., SAID ANNULUS BEING FORMED BY AN INTERNAL CONCENTRIC BAFFLE RADIALLY SPACED FROM THE INTERNAL WALL OF SAID UPPER PORTION OF SAID CIRCULAR COKING VESSEL, SAID BAFFLE EXTENDING DOWNWARDLY BELOW SAID PSEUDO-LIQUID LEVEL AND FORMING A CENTRALLY LOCATED CONDUIT, PASSING GASEOUS MATERIAL UPWARDLY THROUGH SAID COKING VESSEL AT A VELOCITY SUFFICIENT TO MAINTAIN SAID BODY OF SOLIDS IN A DENSE TRUBULENT FLUIDIZED STATE, MAINTAINING SAID OIL WITHIN SAID COKING VESSEL FOR A PERIOD SUFFICIENT TO CONVERT THE SAME INTO VAPORS AND COKE, AND WITHDRAWING VAPORS SO FORMED FROM THE TOP OF SAID VESSEL THROUGH SAID CENTRALLY LOCATED CONDUIT.
