A METHOD FOR CONVERTING A HEAVY PETROLEUM FRACTION TO LIGHTER HYDROCARBON MATERIALS WHICH COMPRISES IN COMBINATION THE STEPS OF PASSING A FIRST PORTION OF PEBBLES INTO THE UPPER PORTION OF A PEBBLE HEATING ZONE; PASSING A HOT FLUID HEATING MATERIAL THROUGH SAID HEATING ZONE SO AS TO RAISE SAID FIRST PEBBLES TO A TEMPERATURE WITHIN THE RANGE OF FROM 2000* F. TO 3200* F.; REMOVING GASEOUS EFFLUENT MATERIALS FROM SAID PEBBLE HEATING ZONE; PASSING SAID HEATED FIRST PEBBLES INTO A REACTION ZONE; BY-PASSING SAID HEATING ZONE WITH A SECOND PORTION OF PEBBLES AND INTRODUCING SAID SECOND PORTION OF PEBBLES INTO A CONTACT ZONE; INTRODUCING SAID HEAVY PETROLEUM INTO SAID CONTACT ZONE AND COATING SAID SECOND PEBBLES WITH ONLY SAID HEAVY PETROLEUM; PASSING SAID PETROLEUM COATED SECOND PEBBLES FROM SAID CONTACT ZONE INTO SAID REACTION ZONE AT A TEMPERATURE WITHIN THE RANGE OF FROM 300* F. TO 800* F.; ADMIXING SAID HEATED FIRST PEBBLES AND SAID PETROLEUM COATED SECOND PEBBLES IN SAID REACTION ZONE AND RAISING SAID HEAVY PETROLEUM TO REACTION TEMPERATURE THEREBY; REMOVING GASEOUS REACTION PRODUCTS FROM SAID REACTION ZONE; REMOVING SAID PEBBLES FROM SAID REACTION ZONE; RETURNING A FIRST PORTION OF SAID PEBBLES TO SAID PEBBLE HEATING ZONE; AND RETURNING THE BALANCE OF SAID PEBBLES TO SAID CONTACT ZONE.
