| titleOfInvention | A kind of preparation method of EMT molecular sieve membrane |
| abstract | The invention relates to a preparation method of an EMT molecular sieve membrane, comprising the following steps: 1: according to the molar ratio of Al 2 O 3 :SiO 2 :Na 2 O:template agent:H 2 O is 1:(1～50):(0.1 ～10):(0～1.0):(20～400) Weigh the aluminum source, silicon source, sodium hydroxide, template agent, and fully dissolve in deionized water, stir continuously, stand and age to get the precursor 2. Immerse the pretreated ceramic support body in the precursor sol, apply the vacuum filtration process to coat the molecular sieve precursor sol on the surface of the pretreated ceramic support body, and then dry it to obtain the molecular sieve precursor sol. 3. Place the ceramic support coated with molecular sieve precursor sol in a reaction kettle with deionized water at the bottom, seal and crystallize, then wash, dry, and activate by roasting to obtain EMT molecular sieve membrane . Compared with the prior art, the EMT molecular sieve membrane prepared by the present invention has better deep removal performance when adsorbing the polar oxygen-containing compound impurities in the olefin stream. |
