摘　　要：利用硅橡胶／聚砜复合膜进行了正庚烷／氮气分离的实验研究．结果表明，渗透侧真空度、原料气浓度、操作温度及渗透气与原料气的流量比对该分离过程有很大的影响．实验得到：当处理量为４．８ｍ３／（ｍ２·ｈ）时，正庚烷脱除率可达到９０％左右．The research of the separation of n -septane/nitrogen using silicone rubber/polysulpone composite membrane was carried out. It shows that the vacuum of the downstream side,the concentration of the feed stream, the operating temperature and the rate ratio of permeate to feed stream have great influence on the separation process. The result is that the separation ratio of n -septane can reach 90% with a 4.8 m 3 /(m 2 ·h) treating capacity.
