| Abstract: | A-type zeolite membrane was synthesized by the vacuum seeding and secondary growth method. The pervaporation and vapor permeation processes for the separation of ethylene glycol/water mixture，and the effect of separation temperature and EG concentration on the flux were studied. The separation stability of the A-type zeolite membrane reached more than 1 000 h. The separation selectivity and stability were kept at a high value，and the separation factor and flux at 120℃ were 10 000 and 10 kg•m－2•h－1 respectively. |
