Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
124 words
IN A PROCESS FOR THE PRODUCTION OF CARBON MONOXIDE AND HYDROGEN FROM A SOLID CARBONACEOUS FUEL CONTAINING VOLATILIZABLE HYDROCARBONACEOUS CONSTITUENTS, THE IMPROVEMENT WHICH COMPRISES SUBJECTING SAID CARBONACEOUS FUEL IN PARTICLE FORM TO THE ACTION OF AN OXIDIZING GAS IN A DENSE PHASE FLUIDIZED BED GASIFICATION ZONE, DISCHARGING FROM SAID GASIFICATION ZONE GASEOUS PRODUCTS COMPRISING COMPOUNDS CONTAINING BOTH CARBON AND HYDROGEN ATOMS IN THE SAME MOLECULE, AND ADMIXING OXIDIZING GAS WITH SAID GASEOUS PRODUCTS FROM THE GASIFICATION ZONE IN A REFORMING ZONE MAINTAINED AT A TEMPERATURE OF AT LEAST ABOUT 2,000* F. WHEREIN SAID COMPOUNDS ARE CONVERTED INTO CARBON MONOXIDE AND HYDROGEN WHILE PASSING THE GASEOUS MIXTURE THEREIN IN INDIRECT HEAT EXCHANGE RELATIONSHIP WITH THE PARTICLES OF CARBONACEOUS FUEL UNDERGOING GASIFICATION IN SAID GASIFICATION ZONE.
