英文摘要	The syngas derived from a pyrolysis and gasification process was used as a reducing agent to produce iron ore pellets. The reduction temperature was kept between 1123 K and 1323 K, and the time was set 30 min. Results showed that the reducibility increased from 88.1% at 1123 K to 99.95% at 1323 K. The reduction rate increased with increasing reduction temperature. Further, the reaction rate in the early stage was higher than that in the later stage. The X-ray diffraction (XRD) and metallographic microscope analyses of the oxidized pellets and direct reduced iron (DRI) products showed that, the reduction process followed the reaction scheme: Fe2O3 -> FeO -> Fe. A kinetics analysis indicated that, the reduction rate was controlled by an interfacial chemical reaction with syngas and that the activation energy was 104.76 kJ/mol. The effect of syngas as the reducing gas on the reduction of iron ore pellets was similar to that of natural gas. The use of biomass during DRI production can eliminate CO2 emissions, energy crisis, and climate change. (C) 2016 Elsevier B.V. All rights reserved.
