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.
