ABSTRACT
The principles of the integrated processing of high-magnesia siderites have been developed and tested in enlarged laboratory experiments. These principles allow one to increase the level of using the ores in metallurgy and to obtain additional products. It is established that a porous oxide material forms at the stage of roasting high-magnesia siderites accordingly to the patented scheme. The catalytic activity of the material obtained was investigated in the reactions of steam conversion of ethanol and conversion of carbon dioxide by hydrogen. The main products of the catalytic conversion of ethanol by steam in the temperature range of 470 - 550 °C are hydrogen and acetone. The investigated catalyst demonstrate high activity in the reverse water gas shift reaction at a temperature of 820 °C. When activity of the catalyst is reduced it can be agglomerated and used as a burden component in the blast furnace process.
