Abstract:
     The invention relates to a method and a plant for reducing oxide-containing material while simultaneously generating a gas suitable as fuel gas. In this regard, there is produced from carbonaceous and/or hydrocarbon material a reduction gas containing mainly carbon monoxide and hydrogen gas, using thermal energy obtained by partial combustion in a separate gas generating shaft. The temperature of said thus prepared reduction gas is then regulated and said gas introduced into a reduction shaft containing the oxidic material optionally subsequent to desulphurizing said gas. Threrafter the partialy spent reduction gas withdrawn from said reduction shaft is freed from water and solids, thereafter a part-flow of said spent gas may be used as fuel gas, while optionally a further part-flow is returned to the process.
