| 中文摘要 |
| 为探讨干酪根的非均质性与其吸附解吸行为间的关系,采用平衡法研究了菲和1,3,5-三氯苯在3种不同干酪根类型的煤上的吸附与解吸行为.结果表明,菲和1,3,5-三氯苯的吸附解吸等温线均表现出较强的非线性和解吸滞后.吸附解吸行为上的差异可能与干酪根的结构和性质的非均质性有一定的内在关系. |
| 英文摘要 |
| To understand the intercorrelation between the heterogeneity of kerogen and sorptive-desorptive characteristics, the sorption and desorption equilibria of phenanthrene and 1,3,5-trichlorobenzene were measured for three different types of coal (lignite, bark coal and fusinite) using a batch technique. The results show that the sorption and desorption of phenanthrene and 1,3,5-trichlorobenzene are highly nonlinear and significantly hysteretic. The observed sorptive differences among the three coals are explained via the structural and chemical heterogeneity of kerogen. |
