Composition of Synthesis Gas Produced by Intraformation Electrophysical Gasification of Coals at Different Heating Rates

Resumo

Electrophysical intraformational gasification of coals from the Egozovo-Krasnoyarsk, Krasnogorsk, and Balakhta deposits was investigated. The quantitative composition of the synthesis gas was determined. Its heats of combustion at various heating rates were calculated. It was found that the concentrations of H₂ and CO₂ in the obtained synthesis gas decreased whereas that of CO increased if the heating rate was accelerated. The results showed that accelerating the heating rate increased slightly the heat of combustion because the decreased H₂ and CH₄ concentrations were compensated by the increased CO concentration.
