利用煤的形成过程提质褐煤

Using the Formation Process of Coal to Upgrad Lignite

褐煤的高水分量几乎影响褐煤利用的每一方面。为了实现褐煤资源的高效利用,本文中利用煤的形成过程设计了一套褐煤提质工艺,主要是模拟一个高压、高温的环境加速褐煤转变。工艺中要求合适的压力和温度,可以明显提高脱水率。

The high water contained almost affected every aspects of lignite applying.In order to realize efficient use of lignite,a set of lignite upgrading process was designed by using the formation process of coal,which was simulated a high-temperature,high-pressure environment to accelerated the changing of lignite.Upgrading process must control the pressure and temperatrue in the right dose to improve the dewater rate obviously.
