The sorption properties of native and modified petroleum asphaltenes with respect to phenol were studied under static conditions. The asphaltenes were modified by nitration, followed by reduction with sodium sulfide. Sorption isotherms of phenol were constructed on the basis of the obtained data, and equations for the adsorption processes were calculated. It was found that the adsorption isotherms can be described most accurately by the Freundlich and Langmuir equations. It was found that the process occurs as a result of physical adsorption.

石油沥青质的硝基和氨基衍生物对苯酚的吸附

在静态条件下研究了天然和改性石油沥青质对苯酚的吸附性能。沥青质通过硝化改性,然后用硫化钠还原。根据所得数据构建苯酚的吸附等温线,并计算吸附过程的方程式。发现吸附等温线可以通过 Freundlich 和 Langmuir 方程最准确地描述。发现该过程是物理吸附的结果。
