摘要
Abstract
The removal effectiveness of the MOF-808 material for organic chloride in a plastic cracking oil was studied in light of its excellent adsorption properties.The MOF-808 materials was prepared,and then the Zrx∶Fey@MOF-808 ma-terials with different doping ratios were prepared by using a hydrothermal synthesis method.Four typical organic chlo-rides in the plastic cracking oil were selected to prepare a model oil,and the optimal x/y ratio was determined to be 1∶0.67 according to the removal rate of organic chlorides in the model oil.The optimal reaction conditions and reuse perfor-mance of adsorption dechlorination experiments were determined,and the corresponding adsorption mechanism was in-vestigated.The results indicated that the as-prepared Zr1∶Fe0.67@MOF-08 adsorption material exhibited has good struc-ture and stability.The removal rate of chloride in the model oil was as high as 97.66% at an adsorption temperature of 50℃,an adsorption time of 2 h,and an agent/oil mass ratio of 1/40.The dechlorination rate remained to be above 85% after repeatedly using the adsorbent for 6 times.The adsorption process conformed to a pseudo-second-order kinet-ic model,belonging to a spontaneous chemisorption process.关键词
