Abstract 1. IN A CONTINUOUS METHOD OF THE DESTRUCTIVE DISTILLATION OF MATERIAL CONTAINING CARBONACEOUS MATTER OR THE LIKE WITHOUT COMBUSTION IN A VERTICAL COLUMN OF PARTICULATE MATTER HAVING A TOP FEED FOR RAW MATTER AND A BOTTOM DISCHARGE FOR PROCESSED SOLIDS, THEREBY PROVIDING MOVEMENT OF THE PARTICULATE MATTER FROM TOP TO BOTTOM THROUGH THE COLUMN, THE IMPROVEMENT OF (1) WITHDRAWING OFF-GAS PRODUCTS AND OIL MIST FROM A LEVEL INTERNALLY OF SAID COLUMN ADJACENT TO BUT BELOW THE TOP OF THE COLUMN; (2) INTRODUCING A CO2 ENRICHED COOLING GAS INTERNALLY OF SAID COLUMN AT A LOWER LEVEL THEREIN ADJACENT TO BUT ABOVE THE SPENT MATTER DISCHARGE AND INTERNALLY OF THE COLUMN TO COOL THE SPENT MATTER AND TO BE SIMULTANEOUSLY HEATED THEREBY; AND (3) INTRODUCING EXTERNALLY HEATED RECYCLED OXYGEN LEAN OFF-GAS PRODUCTS AT A TEMPERATURE IN EXCESS OF THE DISTILLATION TEMPERATURE INTO SAID COLUMN OF MATTER IN AT LEAST TWO LEVELS IN ABOUT THE CENTRAL PORTION OF THE COLUMN, SAID AT LEAST TWO LEVELS BEING SPACED APART A SUFFICIENT DISTANCE TO PROVIDE THE DESIRED RESIDENCE TIME FOT THE DOWNWARDLY MOVING MATTER TO PRODUCE A PREDETERMINED RETORTING TEMPERATURE LEVEL OF ABOUT 100-12000*F.; SAID RECYCLED GAS HAVING INSUFFICIENT OXYGEN FOR COMBUSTION OF THE CARBONACEOUS MATTER IN THE COLUMN, SAID HEATED GAS JOINING WITH THE RISING NOW HEATED COOLING GAS TO FORM THE HEATING MEDIA FOR THE DISTILLATION OF THE MATTER IN THE CENTRAL PORTION OF THE COLUMN.
IN A CONTINUOUS METHOD OF THE DESTRUCTIVE DISTILLATION OF MATERIAL CONTAINING CARBONACEOUS MATTER OR THE LIKE WITHOUT COMBUSTION IN A VERTICAL COLUMN OF PARTICULATE MATTER HAVING A TOP FEED FOR RAW MATTER AND A BOTTOM DISCHARGE FOR PROCESSED SOLIDS, THEREBY PROVIDING MOVEMENT OF THE PARTICULATE MATTER FROM TOP TO BOTTOM THROUGH THE COLUMN, THE IMPROVEMENT OF (1) WITHDRAWING OFF-GAS PRODUCTS AND OIL MIST FROM A LEVEL INTERNALLY OF SAID COLUMN ADJACENT TO BUT BELOW THE TOP OF THE COLUMN; (2) INTRODUCING A CO2 ENRICHED COOLING GAS INTERNALLY OF SAID COLUMN AT A LOWER LEVEL THEREIN ADJACENT TO BUT ABOVE THE SPENT MATTER DISCHARGE AND INTERNALLY OF THE COLUMN TO COOL THE SPENT MATTER AND TO BE SIMULTANEOUSLY HEATED THEREBY; AND (3) INTRODUCING EXTERNALLY HEATED RECYCLED OXYGEN LEAN OFF-GAS PRODUCTS AT A TEMPERATURE IN EXCESS OF THE DISTILLATION TEMPERATURE INTO SAID COLUMN OF MATTER IN AT LEAST TWO LEVELS IN ABOUT THE CENTRAL PORTION OF THE COLUMN, SAID AT LEAST TWO LEVELS BEING SPACED APART A SUFFICIENT DISTANCE TO PROVIDE THE DESIRED RESIDENCE TIME FOT THE DOWNWARDLY MOVING MATTER
