摘　　要：以5A分子筛为吸附剂,吸附分离石脑油中的正构烷烃。用于吸附的分子筛质量为50 g,吸附温度为150℃时,原料油加量为80 mL时吸附效果最好,吸附率为59.07%。脱附温度为200℃时,确定较佳的N2吹扫速度约为2 mL/s,脱附时间为20～30 min,在此条件下脱附率为100%,平均收集率为62.47%。5A Molecular sieves are used to adsorbing and separating normal paraffin from naphtha. The ad- sorption effect is best with the adsorption rate of 59.07% when the mass of molecular sieves used for adsorbing normal paraffin is 50 g, the adsorbent temperature is 150 ℃ and the volume of feedstock oil is 80 mL. When the desorption temperature is 200 ℃, the preferred N2 purging rate and the desorption time identified are 2 mL/s and 20 to 30 min respectively. The desorption rate is 100% and the average collection rate is 62.47% at such conditions.
