NANOCRYSTALLINE INORGANIC BASED ZEOLITE AND METHOD FOR MAKING SAME |
摘要 |
A method for making a zeolite includes impregnating a porous inorganic oxide with a liquid solution containing an inorganic micropore-forming directing agent. The amount of liquid solution is no more than about 100% of the pore volume of the porous inorganic oxide, and the concentration of the directing agent in the liquid solution ranges from 21% to about 60% by weight. The impregnated amorphous inorganic oxide is heated at a synthesis temperature of from about 50° C. to about 150° C. for a duration of time sufficient to form a zeolite-containing product. The method herein is advantageous for the transformation of a mesoporous or macroporous amorphous inorganic material to a composite structure containing the original mesoporous or macropores, but wherein at least some of the porous inorganic oxide material is converted to nanocrystalline zeolite, such as zeolite Y. |
