摘　　要：介绍了加压气流床煤气化工艺和加压固定床煤气化工艺固有的优点和缺点。分析了加压气流床煤气高温显热的利用率,探讨了加压固定床蒸汽消耗高、废水处理成本高和气化工艺氧耗低的原因。认为煤制天然气选择加压固定床煤气化工艺具有更多的优点。Inherent advantages and disadvantages of the pressurized entrained flow coal gasification process and the pressurized fixed bed coal gasification process is introduced. By analyzing the utilization rate of the high temperature sen- sible heat from the gas gained from the pressurized entrained flow coal gasification process and the comparison of the fea- tures between two different pressurized gasification processes the paper concluded that the pressurized fixed bed coal gasi- fication is a more advantageous process in producing SNG.
