Claim 1
Independent Claim
128 words
THE PROCESS OF CONVERTING SOLID CARBONACEOUS FUELS INTO GASES CONTAINING CARBON MONIXIDE BY AND ENDOTHERMIC REACTION WITH A GASEOUS GASIFYING MEDIUM CONDUCTED AT AN ELEVATED CONVERSION TEMPERATURE IN A CONVERSION ZONE, WHICH COMPRISES CONTACTING CARBONACEOUS SOLIDS WITH A SUFFICIENT AMOUNT OF SAID GASIFYING MEDIUM AT AT CONVERSION TEMPERATURE TO CONVERT A SUBSTANTIAL PROPORTION OF THE CARBON OF SAID FUELS INTO SAID GASES IN SAID CONVERSION ZONE, WITHDRAWING PRODUCT GAS FROM SAID CONVERSION ZONE, WITHDRAWING SOLID CARBONACEOUS GASIFICATION RESIDUE FROM SAID CONVERSION ZONE, PASSING SAID WITHDRAWN RESIDUE TO A HEATING ZONE, SUBJECTING SAID RESIDUE IN SAID HEATING ZONE AT A HEAT-GENERATING INCOMPLETE COMBUSTION AT A TEMPERATURE SUBSTANTIALLY ABOVE SAID CONVERSION TEMPERATURE AND BELOW THE FUSION POINT OF ITS ASH, WITHDRAWING FLUE GAS FROM SAID HEATING ZONE, WITHDRAWING CARBONACEOUS HEATING
