C10J PRODUCTION OF PRODUCER GAS, WATER-GAS, SYNTHESIS GAS FROM SOLID CARBONACEOUS MATERIAL, OR MIXTURES CONTAINING THESE GASES (synthesis gas from liquid or gaseous hydrocarbons C01B; underground gasification of minerals E21B43/295); CARBURETTING AIR OR OTHER GASES
Introduced: September 1968
Description
C10J covers gasification and carburetting processes that convert solid carbonaceous feedstocks (coal, coke, biomass, waste) into synthesis gas (CO and H₂) through partial oxidation with oxygen or steam. This includes fixed-bed, fluidized-bed, and entrained-flow gasifiers, as well as processes for enriching gases with carbon monoxide through chemical reactions. The classification encompasses both the reactor technologies and the chemical conversion methods used in syngas production for subsequent synthesis of chemicals, fuels, or power generation. Excluded are complete combustion processes (covered under thermal power generation) and hydrogen production from non-carbonaceous sources.
