摘要
Abstract
With the self-made 13X zeolite as the carrier,the 13X zeolite was modified by the impregnation method loaded with polyethylenimine(PEI),and 13X-PEI adsorbent was prepared.The adsorbent was characterized by N2 adsorption-desorption,XRD,NH3-TPD,FTIR,Py-IR,and the adsorption and dechlorination performance of 13X-PEI adsorbent on unpolymerized C5 simulated oil was investigated.The experimental results show that PEI is successfully loaded into the pore of the 13X zeolite and causes no damage to the microporous structure of the 13X zeolite.The total acid content of 13X-PEI adsorbent increases,and the specific surface area decreases.The adsorption capacity is better than that of the 13X zeolite.Under the conditions of an adsorption temperature of 30℃and a volume space velocity of 1.0 h-1,the penetrating time of 13X-PEI adsorbent is 48 h,and the maximum penetrating adsorption capacity is 28.8 mg/g.关键词
