Abstract:

The iron and steel making industry is one of the most intensive energy consuming in the industrial sector. In iron-making blast furnace, the energy cost is about 50% of the total coal. Moreover, the CO2 emission is accounted to be more than 70% of the total emission of the integrated steel plants. Using climate-neutral biomass in the blast furnace as a replacement for fossil carbon is expected to significantly reduce the consumed energy and have large positive effect on the environmental objectives of reducing CO2 emission. The present work is an attempt to efficiently utilize carbon containing biomass in the blast furnace. Thermogravimertic analysis is used to study the devolatilization and reduction behavior of biomass-iron oxide self-reducing mixtures. The reaction progress was tracked by online monitoring of the mass loss with time. Moreover, the evolved gases were continuously analyzed by means of quadruple mass spectroscopy.
