摘　　要：为减少CO2排放量对人类生存和发展造成的不利影响,在前人研究的基础上,以神府低发热值煤(Ⅲ)和澳矿粉(AMP)为原料,以沥青为粘结剂,用热压成型法制备出不同澳矿含量的含铁型焦(CIC)。用SEM-EDS、X射线衍射仪和热重分析仪测定含铁型煤和CIC试样的微观组织、物相和气化反应起始温度等,研究AMP含量对CIC化学性能的影响及其反应机理。结果表明,CIC中的Fe原子量、气孔数量和尺寸随AMP含量增加而增加;CIC气化起始温度随AMP含量增加而降低,从936.5℃逐渐降低到876.3℃。为高炉炼铁实现节焦节能提供一定的实验基础。CO2emission has negative effects on human survival and development.Shenfu coal-Ⅲ and Australian miner powder(AMP)were mixed to fabricate carbon iron composite(CIC)by hot pressing.Then the effects of AMP content on properties of CIC,such as microstructure,phase,and starting temperature of CIC gasification reaction,were investigated by XRD,SEM-EDS and DSC.The results show that the fraction of Fe atoms and pores in CIC increased with the increase of AMP content.Owing to the catalytic effect of Fe on CIC,the starting temperature of gasification reaction dropped from 936.5℃to 876.3℃.
