Method of producing hydrogen and carbon-oxide-containing process gases for use for reducing ores

Abstract

Abstract A method of producing hydrogen and carbon-oxide-containing gases for use for reducing ores and synthesizing hydrocarbons and oxygen-containing organic substances, comprises, directing a suspension of finely ground coal and oxygen through a burner into a pressure reactor to convert the coal into gases and partly burning the gases, separating the gases from non-converted coal and ash, directing the separated gases into a quenching water so that their heat content is converted into pressure steam and the gases are precooled. The precooled gases are further purified and further cooled. During quenching, the gases are cooled from temperatures in the range of from 1300° C. to 1500° C. down to 200° C. to 300° C., depending on the gasification pressure. The ash-free gases then become highly loaded with steam to a steam-to-gas ratio of 2 as they are cooled down to a temperature of from between 100° C. to 200° C., and to also form a condensate. The condensate is separated from the gases and recycled into the quenching process and the gases are further cooled to a temperature of from 4° C. to 80° C. and subsequently directed to the synthetic or ore-reducing process.
