| titleOfInvention |
molecular sieve ceramic membrane material for olefin purification and preparation and application thereof |
| abstract |
The invention relates to molecular sieve ceramic membrane materials for olefin purification and preparation and application thereof, wherein the particle size of molecular sieve particles loaded on the surface of a ceramic material in the molecular sieve ceramic membrane materials is 0.1-3 mu m, the thickness of a molecular sieve layer is 3-5 mu m, the molecular sieve ceramic membrane materials are prepared by ceramic material pretreatment, molecular sieve seed crystal precoating and closed crystallization in sequence, and the molecular sieve ceramic membrane materials are used for removing polar oxygen-containing compounds in gaseous olefin flow to below 1 ppm. |
