Heavy oil fractions in the presence

Claim 1

A CONTINUOUS PROCESS FOR SEPARATELY CONVERTING LIGHT AND HEAVY HYDROCARBON FRACTIONS IN THE PRESENCE OF SUBDIVIDED CONTACT MATERIAL, WHEREIN A SINGLE HEATING AND REGENERATION ZONE FOR THE COMBUSTION OF CARBONACEOUS CONTAMINANTS FROM SAID CONTACT MATERIAL AND SEPARATE CONVERSION ZONES ARE UTILIZED AND THE SUBDIVIDED PARTICLES ARE CONTINUOUSLY PASSED FROM ONE CONTACTING ZONE TO ANOTHER, THE IMPROVEMENT WHICH COMPRISES PASSING THE FRESHLY REGENERATED AND HEATED PARTICLES TO A FIRST CONVERSION ZONE AND INTO CONTACT THEREIN WITH A CHARGE THE HYDROCARBON CONTENT OF WHICH CONSISTS SOLELY OF SAID LIGHT HYDROCARBON FRACTION, SEPARATING RESULTING FLUID CONVERSION PRODUCTS FROM THE CONTACTED PARTICLES AND DISCAHRGING THEM FROM THE FIRST CONVERSION ZONE INTO A FRACTIONATING ZONE, CONTINUOUSLY PASSING CONTACTED PARTICLES UPON THEIR SEPARATION FROM SAID FLUID PRODUCTS FROM THE FIRST TO A SECOND CONTACTTING AND CONVERSION ZONE AND THEREIN CONTACTING THEM FIRST WITH SAID HEAVY HYDROCARBON FRACTTION AND THEN COUNTERCURRENTLY WITH A HEATED LOWER BOILING RECYCLE STREAM, SAID RECYCLE STREAM BEING HEATED TO A TEMPERATURE SUFFICIENT TO MAINTAIN SAID SECOND CONTACTING ZONE AT AN AVERAGE TEMPERATURE AT LEAST EQUAL TO THAT MAINTAINED WITHIN SAID FIRST CONTACTING ZONE, SEPARATING RESULTING FLUID CONVERSION PRODUCTS FROM THE SOLID PARTICLES IN SAID SECOND CONTACTING ZONE AND COMMINGLING THEM WITH THE SEPARATED FLUID PRODUCTS BEING DISCHARAGED FROM SAID FIRST CONVERSION ZONE INTO SAID FRACTIONATING ZONE, AND CONTINUOUSLY PASSING RESULTING COKED AND CONTAMINATED SUBDIVIDED PARTICLES FROM SAID SECOND CONTACTING ZONE TO SAID REGENERATION ZONE.
