摘要

以数字方式预测了用于石化系统净化的碳材料的吸附特性。更精确地阐明了苯乙烯在不同大小孔隙中的吸附机理，并计算了考虑和不考虑水介质的苯乙烯吸附能。建立了 "结构-吸附活性 "关系，并确定了导致碳吸附剂吸附容量增加的特征：确定了吸附剂碳材料的适宜孔径，以确保从水介质中充分有效地吸附苯乙烯。使用 AG-3 和 BAU 商用碳吸附剂从水介质中吸附苯乙烯的实验研究证实了既定机制的有效性。

Styrene Adsortion from Styrene–Water System with Carbon Sorbents

The adsorption properties of carbon materials for purification of petrochemical systems were predicted digitally. The mechanism of styrene adsorption in pores of various sizes was clarified more precisely and the styrene adsorption energies were calculated with and without taking account of the aqueous medium. The “structure-adsorption activity” relationship was established and the characteristics responsible for increase in adsorption capacity of carbon sorbents were identified: the expedient pore size of the carbon material of the adsorbent was determined to ensure sufficient effectiveness of styrene adsorption from aqueous medium. The experimental studies of styrene adsorption from aqueous medium using commercial AG-3 and BAU carbon sorbents confirm the validity of the established mechanisms.
