Distillation of carbonaceous solids

Claim 1

A METHOD FOR PRODUCING VALUABLE HYDROCARBON LIQUIDS AND GASES FROM HYDROCARBONACEOUS SOLIDS WHICH COMPRISES MAINTAINING AN AGITATED AND DESCENDING BED OF SAID SOLIDS IN CONTINUOUS TRAVEL THROUGH A SERIES OF CONTACT ZONES WITHIN A RETORT, CONTACTING SAID SOLIDS BED WITH A HEATED GASEOUS MEDIUM IN A PRE-HEATING ZONE, PASSING SAID BED TO A FIRST DISTILLATION ZONE, AND CONTACTING WITH A SECOND HEATED GASEOUS MEDIUM TO EFFECT DISTILLATION OF VAPOROUS AND GASEOUS PRODUCTS THEREFROM, PASSING SAID BED TO A SECOND DISTILLATION ZONE AND CONTACTING THEREIN WITH A THIRD HEATED GASEOUS MEDIUM TO EFFECT A HIGHER TEMPERATURE DISTILLATION OF VAPOROUS PRODUCTS THEREFROM, PASSING SAID BED TO A BURNING ZONE AND CONTACTING THEREIN WITH A GAS CONTAINING FREE OXYGEN TO EFFEECT OXIDATION OF COMBUSTIBLE MATERIAL THEREIN, PASSING THE HOT OXIDIZED SOLIDS BED TO A HOT GAS PRODUCING ZONE AND CONTACTING SAID SOLIDS BED THEREIN WITH SAID THIRD GASEOUS MEDIUM PRIOR TO PASSING IT WITH OBSORBED HEAT TO SAID SECOND DISTILLATION ZONE, PASSING SAID SOLIDS BED TO A COOLING ZONE AND CONTACTING SAID BED THEREIN WITH SAID SECOND MENTIONED GASEOUS MEDIUM PRIOR TO PASSING IT WITH ABSORBED HEAT TO SAID FIRST DISTILLATION ZONE, PASSING SAID SOLIDS BED TO A FINAL COOLING ZONE AND CONTACTING SAID BED THEREIN WITH THE FIRST MENTIONED GASEOUS MEDIUM PRIOR TO PASSING IT WITH ABSORBED HEAT TO SAID PRE-HEATING ZONE.

Claim 2

A METHOD FOR PRODUCING VALUABLE HYDROCARBON LIQUIDS AND GASES FROM HYDROCARBONACEOUS SOLIDS WHICH COMPRISES MAINTAINING AN AGITATED AND DESCENDING BED OF SAID SOLIDS IN CONTINUOUS TRAVEL THROUGH A SERIES OF CONTACT ZONES WITHIN A RETORT, CONTACTING SAID SOLIDS BED WITH A HEATED GASEOUS MEDIUM IN A PRE-HEATING ZONE, PASSING SAID BED TO A FIRST DISTILLATION ZONE, AND CONTACTING WITH A SECOND HEATED GASEOUS MEDIUM TO EFFECT DISTILLATION OF VAPOROUS AND GASEOUS PRODUCTS THEREFROM, PASSING SAID BED TO A SECOND DISTILLATION ZONE AND CONTACTING THEREIN WITH A THIRD HEATED GASEOUS MEDIUM TO EFFECT A HIGHER TEMPERATURE DISTILLATION OF VAPOROUS PRODUCTS THEREFROM, PASSING SAID BED TO A BURNING ZONE AND CONTACTING THEREIN WITH A GAS CONTAINING FREE OXYGEN TO EFFEECT OXIDATION OF COMBUSTIBLE MATERIAL THEREIN, PASSING THE HOT OXIDIZED SOLIDS BED TO A HOT GAS PRODUCING ZONE AND CONTACTING SAID SOLIDS BED THEREIN WITH SAID THIRD GASEOUS MEDIUM PRIOR TO PASSING IT WITH OBSORBED HEAT TO SAID SECOND DISTILLATION ZONE, PASSING SAID SOLIDS BED TO A COOLING ZONE AND CONTACTING SAID BED THEREIN WITH SAID SECOND MENTIONED GASEOUS MEDIUM PRIOR TO PASSING IT WITH ABSORBED HEAT TO SAID FIRST DISTILLATION ZONE, PASSING SAID SOLIDS BED TO A FINAL COOLING ZONE AND CONTACTING SAID BED THEREIN WITH THE FIRST MENTIONED GASEOUS MEDIUM PRIOR TO PASSING IT WITH ABSORBED HEAT TO SAID PRE-HEATING ZONE.
