摘要： 制备了一种多孔的聚合物吸附载体，并考察了在汽油模拟体系进行深度脱硫的效果. 载体的多孔性质有利于提高脱硫的吸附容量和选择性. 在正辛烷与二苯并噻吩组成的模拟体系中，DBT的初始浓度为1.26 g/L，吸附载体用量为50 g/L，测得吸附载体的吸附量为16 mg/g，脱硫率达到88%.

Abstract: A porous polymeric sorbent was prepared with sucrose as pore-forming additive, and the sorbent beads are superior to non-porous polymeric sorbent in adsorption of DBT from a model gasoline. Adsorption of 16 mg/g DBT was achieved under the condition of 50 g/L of the polymeric beads at initial DBT concentration of 1.26 g/L. The sorbent beads are easily desorbed with toluene and can be reused with stabilized adsorption capacity.
