摘要
Abstract
A seeding method by rubbing-dipcoating and induction with ball-milled seeds was developed to synthesize NaA zeolite membrane. The synthesis approach could improve the rate of qualified membranes and reduce the synthesis time efficiently,which is suitable for large-scale production of zeolite membranes. Mass transfer mechanism of organic solvent and water in a zeolite membrane was investigated with molecular simulation method. The stability of NaA zeolite membranes in hydrothermal,acid-base and salty environments was systematically stud-ied. A pretreatment method was then proposed and industrial pervaporation plants were built up, which have been operated steadily for long term.关键词
