ABSTRACT:
A method for producing crystalline synthetic faujasite of the zeolite "X" type is disclosed. The method comprises (a) separately preparing a sodium silicate solution and a sodium aluminate solution, (b) admixing the sodium silicate solution and the sodium aluminate solution at high shear until a mixture results having a ratio of sodium oxide to silica of 0.4:1 to 2:1, silica to alumina of 2.2:1 to 3.5:1, and water to sodium oxide of 20:1 to 70:1, (c) heating said mixture to a temperature of about 80.degree. to 120.degree. C. in the absence of any further mixing for a period of time sufficient to produce the desired crystalline faujasite of the zeolite "X" type, and (d) recovering said zeolite "X".
