Abstract

The article deals with a sophisticated approach to the study of basic kinetic dynamic process in metal production. It is concerned with three agendas: study of reduction reactions of iron oxides and carbon as reducing agents with secondary created oxides; study of the e ect of catalyst occurrence on the reaction space; study of the eff ect of variable temperature and pressure gradients on the processes. The main experiments
were carried out in the newly established Laboratory for Research on High Temperaturev Properties equipped with testing setup and upgraded with interpretive model system, enabling a generalization of experimentally obtained information to theoretical conclusions about processing of non-standard alternative and waste materials.
