Abstract：In order to optimize the dense phase conveying system in dry coal gasification process, the dense phase pneumatic conveying technology under high pressure and solid conveying pump based on the theory of solid mechanics of granular media were introduced. The characteristics and critical process of the two methods were summarized.The development trend of solid conveying pump under high pressure was introduced.The fundamental research about granular media statics and dynamics, the function relationship between coal types,moisture,particles size and friction coefficient were the focus of the research.The maximum delivery pressure of Stamet Pump and PWR which provided for the coal types in China was researched.Concerning the bottleneck of XTL industrial scale-up,we also put forward the solutions.
