摘要：

Equilibrium isotherms and isobars have been measured for a series of aromatic hydrocarbons (benzene, toluene, xylene, mesitylene, tetramethylbenzene, naphthalene, hexamethylbenzene, dimethylnaphthalene, and anthracene) on well-defined crystals of NaX zeolite. Henry constants, energies of adsorption, and complete isotherms are reported. The isotherms for the higher molecular weight species approach the ideal Langmuir form with a saturation capacity close to 1 molecule/cage. Heats of sorption increase linearly with carbon number, and there appears to be little difference in either the isotherms or the heats of sorption for different aromatic sorbates of the same carbon number.
