Abstract: At present,there are some problems with crushed coal pressurized gasification technology,such as more byproduct,more gasification wastewater and more refractory gasification wastewater and so on,which have restricted the application of crushed coal pressurized gasification technology.In order to solve these problems,after carefully analyzing the principle of pressurized fixed bed gasification,find out that it is not choosing the suitable gasification coaland put forward the requirements of raw coal that is fit for crushed coal pressurized gasification technology.By analyzing the coal analysis of lignite,long flame coal,lean coal,anthracite,propose that the anthracite is the most suitable types of crushed coal pressurized gasification technology.At the same time,combined with the main industrial operation parameters of the lignite,long flame coal,lean coal and anthracite,further verify that the anthracite coal is most suitable for coal gasification technology and the actual industrial operation result shows that using the anthracite can radically reduce the amount of gasification wastewater and the disposed difficulty.
