化学 渗透汽化 It is found that the pervaporation performance of PDMS/silicalite-1 membranes is much better than that of pure PDMS membrane. 实验结果表明: PDMS/silicalite-1膜分离乙醇/水体系的渗透汽化性能明显优于纯PDMS膜。 渗透蒸发 Comparing with chitosan control membrane CS-TEOS membrane with 6wt. % TEOS mass ratio exhibited a remarkably improved pervaporation performance with separation factor 460 and flux 281g/m2 h under the identical experimental condition. at 80℃for 90wt. 以GA为交联剂制备季铵化壳聚糖膜用以渗透蒸发分离90wt.%乙醇/水体系,考察了GA的含量及渗透蒸发操作条件对膜的溶胀吸附性能和渗透蒸发性能的影响。 蒸发法 全蒸发
