37.熱量測定による石炭表面と溶剤との相互作用の評価(II)

抄録

Previously, in our research, the adsorption of methanol, THF and tetralin at coal surface was investigated by flow microcalorimetric measurement and it was found that these solvents interact with coal surface quite differently. In order to examine the interactions of coal surface and solvent quantitatively, not only adsorption and desorption heat, but also adsorption and desorption amount were measured in this research. Based on the experimental results, amount and molar heat of adsorption were determined for both strong and weak adsorption. It was found that although the amount of strong adsorption is only several percent of all the adsorption amount, more than 20% of adsorption heat results from the strong adsorption.
