研究了不同条件改性后油页岩对苯酚的吸附能力,讨论了改性油页岩对苯酚的吸附动力学和Freundlich等温吸附方程。结果表明,经950℃热解2h、10%NaOH溶液改性及500K2热解4h、65%HNO。溶液改性的两种油页岩对苯酚具有很好的吸附能力,且前者的吸附能力远大于后者,前者的吸附方式主要为化学吸附,后者主要为物理吸附。
The absorption capability to phenol of oil shale modified under different conditions is studied. The absorption dynamics and Freundlich isothermal equation of modified oil shale to phenol are discussed. The results show that one oil shale modified by 10% NaOH solution based on 2h pyrolysis at 950℃and the other modified by 65% HNO3 solution based on 4h pyrolysis at 500℃ have good absorption capability to phenol. Moreover, the absorption capability of the former is far better than that of the latter. The mode of the former absorption is mostly chemical absorption while the latter is mostly physical absorption.
