ADSORPTION EXPERIMENT OF EXTRA-HIGH RANK COAL UNDER THE CONDITION OF EQUILIBRIUM MOISTURE CONTENT

College of Mineral Resource and Environment Sciences, CUMT, Xuzhou, Jiangsu 221008, China

摘要

摘要: 鉴于国内外对镜质组最大反射率R_o(max)大于4.0%的特高煤级煤的吸附特性研究的空白,作者系统地采集了12个R_o(max)>4.0%的煤样进行了平衡水条件下的高压等温吸附实验,分析了特高煤级煤样的朗格缪尔常数与R_o(max)、显微煤岩组分、比孔容和比表面积的关系,发现了煤的朗格缪尔体积随煤级变化的拐点是在R_o(max)为4.5%左右。在上述研究的基础上,文中探讨了煤的吸附特征及机理。

Abstract: In view of the gaps existing in the adsorptive characteristics research of extra high rank coal whose vitrinite has the maximum reflectance(R_o(max))of more than 4.0%,twelve coal samples(R_o(max)>4.0%)were collected systematically and conducted a high pressure and isothermal adsorption experiment under the condition of equilibrium moisture content,and the relationships between the Longmuir constant of extra high rank coal samples and R_o(max),maceral,specific pore volume or specific surface area were analyzed.It was found that inflection point on the curve of Longmuir volume vs.coal rank is around R_o(max)=4.5%.On the basis of above research,the adsorptive characteristics and mechanism of coal were discussed.
