| 摘 要： | 通过对吸附率(有效吸附系数)Ks和饱和吸附量msat的测量,描述了粘度为0.001 Pa·s～0.850 Pa·s的各种油类在膨胀石墨柱中的吸附动力学,发现吸附率Ks对油类粘度有很强的相关性.吸入膨胀石墨柱中的饱和吸附量msat几乎恒定在50kg/kg,该值略低于由膨胀石墨块直接浸渍在油中测得的吸附容量,这是由于所吸附的油沿膨胀石墨柱高度存在重力梯度.

| Abstract: | The sorption kinetics of various oils with viscosities from 0. 001 to 0. 850 Pa· s onto an exfoliated graphite column was characterized by measuring sorptivity ( effective sorption coefficient) Ks and saturated amount of sorption msat. A strong dependence of Ks on oil viscosity was observed. msat was almost constant at 50 kg/kg, which was a little smaller than that measured by direct soaking of a lump of exfoliated graphite in oil. This was because of a gradient of sorbed oil along the height of the exfoliated graphite column. |
