热力改性对低阶煤种成浆性影响的研究 - -

阐述了节约炼焦煤资源,扩大制备水煤浆煤种范围的必要性。介绍了神府低阶煤种经热力改性处理,可提高成浆浓度的研究结果,为低阶煤等难制浆煤种制备水煤浆提供了重要技术支持。 The necessity of expanded coal rank for CWM production and saving coking coal resources were dis- cussed in this paper.Shenfu coal (a kind low rank coal) was used to produce high concentration CWM through de -watering and upgrading technology treatment.The research achievement provided an important technique to sup- port for low rank coal CWM production
