摘　　要：评述了现代煤气化技术开发现状 ,对加压固定床气化 ,流化床气化 ,水煤浆气流床气化和干粉气流床气化典型代表技术的发展进行分析。结合热力学和动力学分析提出了未来煤气化技术发展的原则。鉴于目前制氧成本仍然是制约煤气化技术发展的最大因素 ,认为一方面应加速高效廉价的大规模制氧技术的开发 ,另一方面要注重氧耗低的气化技术的开发 ,重视过程集成概念和技术经济的优化。理论分析和已有研究表明粉煤 块煤双粒级进料液态排渣固定床气化、两段 (多段 )进料干粉气流床气化。The development status of modern coal gasification technology is reviewed Analysis on the development concepts for several typical gasification processes has been conducted Based on the thermodynamics and kinetics of carbon gasification, the principle of future coal gasification development is proposed Because air separation for oxygen making with high capital investment and operation cost seriously hinders the progress of coal gasification, on the one hand, R & D of advanced air separation technology should be addressed and speeded up; on the other hand, lower oxygen consumption gasification process might be developed as well by using integration concept From the theoretical and experimental basis it can be seen that slagging fixed bed gasification with pulverized coal injection (two grade particle size stock), entrained flow gasification with two or more stages of dry coal feeding and partial gasification in fluidized bed integrated with entrained flow gasifying or CFB combustion have good prospect
