在碳中和背景下，煤间接液化面临着巨大的碳减排压力。在先进煤间接液化技术基础上，构建了CO2近零排放的煤间接液化和煤气化燃料电池（IGFC）集成系统，通过高温燃料电池直接利用煤制合成气和费托合成尾气高效发电，替代传统的自备电站给煤间接液化过程供电供热，同时实现尾气CO2富集，降低CO2捕集难度。介绍了国内外IGFC技术研究进展，开展了系统集成关键技术IGFC技术研发与示范，依托煤间接液化装置建成了国内首个兆瓦级IGFC技术试验基地，开发了国内首套100 kW级CO2近零排放的IGFC试验示范系统，实现了连续稳定运转，燃料电池系统发电功率101.7 kW，发电效率53.2%，CO2捕集率98.6%，验证了集成系统可行性。

Under the background of carbon neutralization, indirect coal liquefaction is facing huge pressure of carbon emission reduction. On the basis of advanced indirect coal liquefaction technology, an integrated system of indirect coal liquefaction and integrated gasification fuel cell (IGFC) with near zero CO2 emissions has been built. Through high-temperature fuel cells, coal-based syngas and Fischer-Tropsch synthesis tail gas can be directly used for efficient power generation, replacing the traditional self-contained power station to supply power and heat for the indirect coal liquefaction process. At the same time, CO2 enrichment of tail gas is realized, reducing the difficulty of CO2 capture. For the integrated system, the IGFC technical research progress was introduced, and the integrated demonstration of IGFC technology was carried out. Based on the indirect coal liquefaction unit, the first megawatt level IGFC test base in China was built,and the first 100 kW level IGFC test demonstration system with near zero CO2 emissions was developed, realizing continuous and stable operation. The fuel cell system generated 101.7 kW of power, with 53.2% of power generation efficiency and 98.6% of CO2  capture ratio.The feasibility of the integrated system is verified.
