SYNTHESIS GAS PRODUCTION PROCESS Russian patent published in 2004 - IPC

FIELD: alternative fuels. SUBSTANCE: synthesis gas mainly containing hydrogen and carbon monoxide for producing alcohols, ammonia, and Fischer-Tropsch process products with specified H₂/CO ratio within 1.0 to 2.0 is obtained in two stage process comprising partial oxidation stage and catalytic conversion of residual methane with first-stage products. The first stage is accomplished by noncatalytic partial oxidation of natural gas with oxygen to give reaction products characterized by nonequilibrium content of H₂O and CH₄ and wherein O₂/CH₄ molar ratio is approximately 0.76-0.84, after which resulting reaction products are converted with adjusting additives of CO₂ and H₂O or H₂O and CH₄ to produce gas mixture, which undergoes catalytic conversion of residual methane with steam. EFFECT: reduced power consumption. 3 cl, 1 dwg
