摘　　要：煤气化技术是新型煤化工的基础和关键,煤气化技术的选择应用对煤化工项目综合能效和运行稳定性起至关重要的作用。按床层分类对气化技术进行描述,介绍了工业化应用最多的固定床技术和气流床技术。分析了粉煤、水煤浆气流床气化技术和固渣、熔渣固定床气化技术的特点及适用性,提出未来煤气化技术的发展趋势及煤气化技术选择应用的建议。Coal gasification technology is the base and key of modern coal chemical industry. The correct application of the technology plays a vital role in comprehensive energy efficiency of coal chemical project and running stability. According to the bed classification, this paper describes the technologies of the most widely used fixed-bed and entrained-flow bed and analyzes the characteristics and applicabili- ty of pulverized coal, coal-water slurry-flow bed gasifier, solid slag and melten slag fixed-bed gasification technologies. The future development trend of coal gasification technology and some suggestions for technology choice are suggested.
