Fluid catalytic cracking (FCC) diesel provides most polycyclic aromatic hydrocarbons (PAHs) in diesel. The removal of PAHs by adsorption and separation method is an efficient way to obtained purified diesel. As a kind of green economy adsorbent, porous carbon materials (PCMs) have been widely used in the adsorption of gases, aromatics and organic pollutions. Here, by direct carbonization, the PCMs are prepared from the novel Ph-POSS based porous organic polymers (POPs) which possessed high BET surface areas (∼1000 m2/g). The PCMs possess abundant microporosity and O atoms in the skeleton. The PCMs exhibit high PAHs adsorption capacity because of the hierarchical micropore size, high degree of graphitization and abundant O atoms. The strategy of construction PCMs with hierarchical micropore and heteroatoms provides an effective method to remove PAHs in the FCC diesel.

用Ph-POSS基聚合物构建多级多孔碳以高效吸附多环芳烃
流化催化裂化 (FCC) 柴油产生柴油中的大部分多环芳烃 (PAH)。采用吸附分离法去除PAHs是获得净化柴油的有效途径。多孔碳材料(PCM)作为一种绿色经济吸附剂,已广泛应用于气体、芳烃和有机污染物的吸附。这里,通过直接碳化,由新型Ph-POSS基多孔有机聚合物(POP)制备PCM,该聚合物具有高BET表面积(〜1000 m 2 /g)。相变材料在骨架中具有丰富的微孔和O原子。由于分级微孔尺寸、高度石墨化和丰富的O原子,PCM表现出高PAHs吸附能力。具有分级微孔和杂原子的相变材料的构建策略为去除FCC柴油中的PAHs提供了有效的方法。
