ABSTRACT:
A method of simultaneously producing or co-synthesizing a combination of zeolite X and zeolite A by separately preparing a sodium aluminate solution and a sodium silicate solution, adding the sodium aluminate solution to the sodium silicate solution activated with a relatively small amount of zeolite X seed or bulk product, mixing the solutions together under controlled conditions of temperature and time and heating the mixture to a desired temperature for sufficient time to form a product which is a combination of zeolite X and zeolite A of about 40 percent to 60 percent crystalline with the remainder being an amorphous functional binder.
