在分析比较了几种主要煤制气和直接还原工艺的基础上,结合中国的资源特点,提出了180万t/a规模壳牌煤气化与HYL/Energiron竖炉生产直接还原铁的联合工艺流程,并对联合工艺的主要参数进行了计算。结果表明：联合流程在能耗及环保指标上与传统高炉相比具有一定先进性。并对国内不同地区和原料条件下的生产技术经济指标进行了对比,为煤制气生产直接还原铁的工程化提供方案参考。
Based on the analysis of technical features of several coal gasification and direct reduction processes,a 1.8Mt/a combined process of Shell coal gasification and HYL/Energiron direct reduction shaft was proposed with consideration of natural resources availability in China.The technical parameters of new process were calculated.It shows that the energy consumption and emission of the new combined process is better than blast furnace.The economic performance of new process was compared also under different raw material conditions in various regions.A scheme for the engineering of direct reduction was provided through using coal gas as reducing agent.
