Abstract
本发明涉及一种脱硫剂，属于原油稳定轻烃脱硫剂领域。该脱硫剂是由含聚类轮烷结构的聚合物炭化制得，所述含聚类轮烷结构的聚合物为β‑环糊精包合对苯二胺、对苯二胺、间苯二甲酰氯的缩聚物。本发明利用含聚类轮烷结构的聚间苯二甲酰对苯二胺作为炭化的前体，该聚合物具有环糊精单元，与常规聚间苯二甲酰对苯二胺相比，增加了聚合物的碳、氧含量，炭化后，活性炭材料的氧含量增加，极性也有所增加，同时炭材料的孔隙度增加，有利于对极性的硫化物进行吸附，能够较好地脱除原油稳定轻烃中的硫化物。本发明还进一步在含聚类轮烷结构的聚合物上负载了铜，制得的脱硫剂对硫化物的物理、化学吸附作用均得以提高，达到了更好的脱硫效果。
