Abstract:
A method for making a zeolite, comprising the steps of:a) providing a porous inorganic oxide; b) impregnating said porous inorganic oxide with a liquid solution containing a micropore-forming directing agent, wherein the amount of liquid solution is no more than about 100% of the pore volume of the inorganic oxide, and the concentration of the micropore-forming directing agent in the liquid solution ranges from about 25% to about 60% by weight; and, c) heating the impregnated porous inorganic oxide at an elevated synthesis temperature for a duration of time sufficient to form a zeolite-containing product wherein the porous inorganic oxide is raised to the elevated synthesis temperature in a period of time less than about 3,600 seconds.
