压汞法分析煤的孔隙结构研究
nalysis To Porocity Of Coal By Mercury Porosimetry
利用压汞法测定了山西晋城煤样的孔径、比表面积以及孔体积，并由此分析煤样的孔隙结构。结果表明：煤的孔隙结构尚不发达；孔体积随着孔径变小而增大，孔径为0-20nm的孔隙对样品总孔体积贡献较大；煤样的总表面积取决于小孔（孔径小于15nm）体积；煤样中孔半径小于20 nm的孔的数目多，占总孔数的比例大，有利于气体吸附。
Using mercury porosimetry to determine the pore size,special surface area and pore volume of the coal from Jincheng, and analysing the pore structure.It is shown that the pore structure is underdevelopment, pore volume increases with the decreasing of pore size and the pore size between 0-200nm is contributed to pore volume,the small pore(pore size less than 15nm) volume determine special surface area, the number of the small pore(pore size less than 20nm) is large and propitious to gas adsorption.
