METHOD OF SYNTHESIS OF METHANE FROM METHANE-AIR MIXTURE

摘要

FIELD: chemical technology. SUBSTANCE: preliminary refined from mechanical impurities and moisture methane-air mixture, for example, mine gas is fed to conversion in the presence of steam and conversion catalyst. Then oxygenless gas containing CO, CO2 and H2, passes heat-exchangers and drying agent and follows to treatment by absorption with solvent. Gas containing decreased amount of CO2 is fed to methanator where binar gas containing nitrogen and methane forms. Gaseous flow dried in adsorbers passing heat-exchangers and cooling is fed to low-temperature separation in fractionating column. Nitrogen is escaped from upper column part and methane - from bottom one. The synthesized methane is used as fuel. EFFECT: improved method of synthesis. 1 dwgg
