摘要(Abstract):
经过10余年的资源勘查和多学科的综合研究,已基本查明滇东北(昭通市)早石炭世无烟煤的分布、煤质特征及主要利用方向。与国内外其他地区、其他时代的无烟煤比较,本区无烟煤内在矿物质含量极低、有机组分中主要成分为无结构镜质体,有机质中C、H元素高达97%,H/C原子比为0.5。结合X衍射分析(XRD)和高分辨透射电镜(HRTEM)研究结果,该区无烟煤有机质的化学组成与分子构型与沥青中间相炭微球(MCMB)类似。一系列实验表明,经选别制备的超低灰无烟煤是多种中、高端新型炭材料和炭素的优质原料。有序而保护性地开发利用该区资源,对我国经济建设和社会发展具有重要意义。
After more than 10 years of resources exploration and scientific research,the distribution,coal characteristics,and main direction of utilization for the Early Carboniferous anthracite in the northeast of Yunnan Province(Zhaotong) have been basically found out.Compared to anthracites of the other geological ages and/or in other regions worldwide,the anthracite in this region has relatively lower mineral content,dominant collinite,the content of C and H up to 97%,and 0.58 H/C ratio.Results of the X-ray diffraction analysis(XRD) and high-resolution transmission electron microscope(HRTEM) revealed that the chemical composition of organic matter and configuration are similar to those of mesocarbon microbeads(MCMB).The prepared super-low-ash anthracite is a high-quality raw material for a variety of carbons and new carbon-related materials.It is significant both in economic construction and social development in China to exploit such coal resources in order and protectively.
