摘　　要：褐煤是我国煤炭资源的重要组成部分,但褐煤内水高导致其难以制成满足水煤浆气化要求的煤浆,限制了其清洁化利用的途径。本文介绍了国内外褐煤提浓技术的发展状况,分析了水热处理制浆技术的现状,对褐煤制备高浓度水煤浆技术的发展方向和趋势进行了探讨。Lignite is an important part of coal resources in China. But it has a high moisture content, thus it is difficult to make coal slurry which meets the coal slurry gasification requirements, this restrains the ways of clean utilization of lignite. In this paper, the development status of domestic and foreign coal slurry concentration technologies is introduced, the status of hydrothermal treatment slurrying technology is analyzed and the development direction and trend of preparation technologies of high concentration coal slurry from lignite are discussed.
