摘要(Abstract):
中国褐煤资源丰富,由于其煤质特点,利用褐煤时需要进行提质加工。褐煤提质加工技术众多,国内外的褐煤提质加工技术主要包括热解提质加工工艺、脱水提质加工工艺及成型提质加工工艺等。褐煤成型技术可根据用户的不同需求,通过特殊的工艺,克服原煤存在的缺陷,生产出质量优良的产品;解决了褐煤易自燃、水分含量高等对长距离运输及储存不利的问题,具有明显的经济效益和环境效益。综述国内外褐煤众多提质工艺中的成型技术现状,介绍具有代表性工艺技术的主要特点,对比分析了国内外褐煤成型工艺技术的主要指标,总结了褐煤成型工艺技术在中国今后的发展。
There are abundant lignite resources in China,while its utilization is limited by the coal quality,that means it needs to be upgraded.The lignite upgrading technologies at home and abroad include pyrolysis upgrading process,dehydration upgrading process,forming upgrading process and so on.Based on the requirements of users,the lignite forming technologies change some nature of raw coal through special processes,the production is admirable.Once spontaneous combustion and high water content restricted the long-distance transport and storage of lignite,now this technology solves these problems.So this technology has obvious economic and environmental benefits.Summarize lignite forming technologies of many upgrading processes at home and abroad,introduce and compare the main features of representative technologies.Forecast the development trend of lignite forming technologies in China.
