摘要
在小型反应釜上采用直接热压和非极性有机溶剂四氢化萘对内蒙古锡林郭勒褐煤进行脱水提质,获取了在2.5 MPa压力下150、200℃的脱水试样,运用静态氮吸附仪、傅里叶红外光谱、SEM扫描电镜等分析技术对比研究了不同脱水方式煤样的物理、化学结构变化。
Dewatering and upgrading of Inner Mongolia Xilingol lignite by Hot Pressing Dewatering(HPD)and non-polar solvent tetrahydronaphthalene were carried out with a miniature autoclave. By means of Nitrogen adsorption surface analyzer,Fourier transform infrared spectroscopy and Scanning electron Microscopy, the changes of physical and chemical structure of treated samples were explored.
