摘要
Abstract
Removal of dichloroethane in the model oil was studied by the means of adsorption.The modified SAPO-34 zeolite adsorbents with different metal ions were prepared by saturated impregnation with SAPO-34 zeolite as carrier,and Ni2+,Cu2+,Mg2+,Zn2+ metal ions as the active components.The adsorbents were characterized by means of low temperature nitrogen adsorption-desorption (BET),X-ray diffraction (XRD),ammonia adsorption and temperatureprogrammed desorption(NH3-TPD).The adsorption dechlorination effect of the five adsorbents as well as the dechlorination effect of loading amount of the metal ions were investigated,then the optimum adsorbents and the optimum adsorption conditions were obtained.Finally,the regeneration ability of the adsorbent was studied.The results show that Ni / SAPO-34 zeolite has both good adsorption dechlorination and regeneration ability,and the optimum adsorption conditions are as follows:the loading amount of Ni2+ is 4％,adsorption temperature is 20℃,the ratio of catalyst to oil is 1 ∶ 30,and the adsorption time is 50min.This study provides foundation for the removal of organic chlorides in real oil.关键词
