摘　　要：简要介绍了干煤粉与水煤浆2种不同加压气流床煤气化技术的发展现状、技术特点及应用情况,并针对2种典型的干煤粉气流床气化技术以及2种典型的水煤浆气流床煤气化技术进行了综合比较和分析。在此基础上,针对当前大型煤化工项目加压气流床煤气化技术的选择,从原料煤种的适应性、目标产品种类及特点、煤气化装置投资、技术成熟性和可靠性以及项目综合能效等多方面进行了分析和讨论,以期为当前的煤化工项目选择最合适的加压气流床煤气化技术提供参考。最后,对加压气流床煤气化技术的发展趋势进行了展望。A brief introduction is made of current development status, technical features and application situation of two different typical dry pulverized coal and coal water slurry pressurized entrained-bed gasification technologies, and based on two typical dry pulverized coal entrained-bed gasification technologies and two typical coal water slurry entrained-bed gasification technologies, comprehensive comparison and analysis are carried out. On this basis, in connection with choices of pressurized entrained-bed coal gasification technologies of large coal chemical industry projects, analysis and discussion are carried out in many respects, such as adaptability of coal types, types and characteristics of target products, investment of coal gasification unit, maturation and reliability of the technology, comprehensive efficiency of projects etc., providing reference in selection of most suitable pressurized entrained-bed coal gasification technology for current coal chemical industry projects. Finally, development trend of pressurized entrained-bed coal gasification technology is prospected.
