Abstract: This paper summarized research situation of reduction gas used in gas-based direct reduction iron (DRI), analyzed the
technical background, process and technical characteristics of coke oven gas dry reforming transformation and coal gasification
production of DRI technology, introduced upgrading, gasification and metallurgical coupling process of the poor quality of the "three
high" low rank coal pyrolysis that was researched and developed independently, and carried out preliminary analysis of
economic, resources and energy efficiency of the process. Key words: direct reduction iron; reduction gas; coke oven gas; gasification gas; coupling technology
