【摘要】：采用吸附法對模型油中二氯乙烷的脫除進行研究。以SAPO-34分子篩為載體,以Ni2+、Cu2+、Mg2+、Zn2+為活性組分,利用等體積浸漬法制得不同金屬離子改性的SAPO-34分子篩吸附劑。采用低溫氮氣吸附-脫附(BET)、X射線衍射(XRD)和氨吸附及程序升溫脫附(NH3-TPD)對吸附劑進行了表征,考察了5種吸附劑對二氯乙烷的吸附脫氯效果及金屬負載量對脫氯效果的影響,得到了最優(yōu)吸附劑,同時考察了脫氯實驗的吸附條件對脫氯效果的影響,得到了最佳吸附條件,最后研究了吸附劑的再生能力。結果表明:Ni/SAPO-34分子篩的吸附脫氯效果較好,并且有很好的再生能力,其吸附效果的最佳條件為鎳金屬離子的負載量為4%,吸附溫度為20℃,劑油比為1∶30,吸附時間為50min。這一研究為真實油中有機氯化物的脫除提供了經驗和依據。
[Abstract]:The removal of dichloroethane from model oil was studied by adsorption method. SAPO-34 molecular sieve was used as carrier and Ni2 Cu2 / Mg2 / Zn2 as active component. SAPO-34 molecular sieve adsorbents modified by different metal ions were prepared by isobaric impregnation method. The adsorbents were characterized by low temperature nitrogen adsorption-desorption X-ray diffraction (XRD), ammonia adsorption and temperature programmed desorption (NH _ 3-TPD). The adsorption dechlorination of dichloroethane by five kinds of adsorbents and the effect of metal loading on dechlorination were investigated. The optimum adsorbent was obtained. The effect of adsorption conditions on dechlorination was also investigated. The optimum adsorption conditions were obtained. Finally, the regenerative ability of the adsorbent was studied. The results showed that the adsorption dechlorination efficiency of the molecular sieve was better and had a good regeneration ability. The optimum conditions for the adsorption effect were as follows: the amount of nickel ion loading was 4, the adsorption temperature was 20 鈩，
