Conversion of a carbonaceous materialwater slurry

Claim 1

AN IMPROVED PROCESS FOR THE TREATMENT OF A SUSPENSION OF CARBONACEOUS MATERIAL IN WATER TO PREPARE STEAM AND WATER GAS BY THE WEATER-GAS REACTION BETWEEN SAID CARBONACEOUS MATERIAL AND THE WATER, WHICH COMPRISES DIVIDING THE SUSPENSION INTO TWO PORTIONS AND HEATING A FIRST PORTION OF THE SUSPENSION IN A GAS GENERATOR UNDER PRESSURE BY THE TRANSFER OF HEAT FROM HOT FLUIDIZED HEAT TRANSFER MATERIAL TO VOLATILIZE SAID WATER INTO STEAM AT WATER-GAS REACTION TEMPERATURE AND TO CONVERT CARBONACEOUS MATERIAL AND STEAM INTO WATER GAS, SEPARATELY WITHDRAWING THE RESULTING WATER GAS AS A PRODUCT OF THE CONVERSION FROM THE COOLED HEAT TRANSFER MATERIAL, PASSING SAID COOLED HEAT TRANSFER MATERIAL WITH AIR TO A HEATING ZONE, PASSING THE SECOND PROTION OF THE SUSPENSION TO A STREAM SEPERATOR IN THE PRESENCE OF HEATED HEAT TRANSFER MATERIAL, DRYING THE CARBONACEOUS MATERIAL IN SAID SECOND PORTION BY VOLATILIZING THE WATER THEREIN TO STEAM AND SEPERATELY REMOVING THE STEAM FROM THE HEAT TRANSFER MATERIAL AND THE CARBONACEOUS MATERIAL IN THE SEPARATOR AS A PRODUCT OF THE VOLTATILIZITION, PASSING AT LEAST A PORTION OF THE HEAT TRANSFER MATERIAL AND DRIED CARBONACEOUS MATERIAL WITH AIR INTO SAID HEATING ZONE, BURNING SAID CARBONACEOUS MATERIAL IN THE HEATING ZONE IN THE PRESENCE OF THE AIR TO REHEAT SAID HEAT TRANSFER MATERIAL, AND RECYCLING SAID REHEATED HEAT TRANSFER MATERIAL TO SAID GAS GENERATOR AND TO SAID STEAM SEPARATOR.
