Carrier-membrane layer integrated molecular sieve membrane prepared from clay as well as preparation method and application of carrier-membrane layer integrated molecular sieve membrane
The invention provides a carrier-membrane layer integrated molecular sieve membrane prepared from clay as well as a preparation method and application of the carrier-membrane layer integrated molecular sieve membrane prepared from the clay, the clay is prepared into a porous carrier precursor, and then a clay interface on the surface of the carrier precursor is converted into a compact molecular sieve layer; and finally, carrying out high-temperature roasting to obtain the carrier-membrane layer integrated molecular sieve membrane with efficient separation performance. Compared with the prior art, the preparation method has the advantages that the cheap clay is used as a carrier raw material instead of a traditional chemical pure substance, so that the preparation cost of the carrier is reduced, and the roasting temperature of the carrier can be remarkably reduced; a compact clay layer on the surface of the carrier precursor is converted into the molecular sieve membrane by utilizing the characteristic that clay is easily converted into a molecular sieve, so that the compactness of the molecular sieve membrane can be improved; the clay is converted into the molecular sieve membrane by adopting a gas phase conversion method, so that the dosage of chemical reagents can be reduced, the emission of pollutants is reduced, and the effects of energy conservation and environmental protection are achieved.
本发明提供了黏土制备的载体‑膜层一体化分子筛膜及其制备方法和应用，将黏土制备成多孔载体前驱体，然后将载体前驱体表面的黏土界面转化为致密的分子筛层，最后通过高温焙烧获得具有高效分离性能的载体‑膜层一体化分子筛膜。与现有技术相比，本发明以廉价的黏土取代传统的化学纯净物作为载体原料，不仅减少了载体的制备费用，而且可以显著降低载体的焙烧温度；利用黏土易于转化为分子筛的特性将载体前驱体表面致密的黏土层转化为分子筛膜，可以提高分子筛膜的致密性；黏土采用气相转化的方法转化为分子筛膜，可以减少化学试剂的用量，减少污染物的排放量，达到节能环保的效果。
