    摘要: The present invention relates to a process for producing a crystalline synthetic faujasite of the zeolite Y type wherein a relatively small amount of a zeolite Y seed is thoroughly mixed with sodium silicate at ambient temperature to form an activated sodium silicate system and to such activated system, sodium aluminate is added at ambient temperature. The mixture is then heated and reacted with stirring until the desired cyrstalline product is formed. Zeolite Y is filtered out and then dried.

    摘要: The present invention relates to a process for producing a crystalline synthetic faujasite of the zeolite "Y" type wherein an activated system is provided by mixing a sodium silicate solution with a seed amount of zeolite "Y" type synthetic faujasite and the activated system is reacted with a sodium aluminate solution under controlled conditions to thereby form a low water reaction mixture or system and then a crystalline synthetic faujasite of the zeolite "Y" type.

    摘要: Reactive amorphous silica having properties suitable for use in the hydrothermal synthesis of zeolite Y is prepared by chemical precipitation of the silica from the waste liquor from a prior zeolite Y synthesis and is employed as a silica source in a subsequent zeolite Y synthesis.

    摘要: ZEOLITES OF THE Y CRYSTAL TYPE ARE PRODUCED BY DIGESTING AN QUEOUS REACTION MIXTURE COMPRISING SILICAL GEL SYNERIZED AT A PH BETWEEN ABOUT 5.5 AND 10, PREFERABLY BETWEEN ABOUT 6 AND 9, AND SODIUM ALUMINATE AT AN ELEVATED TEMPERATURE. THE PARTICULAR SILICA GEL EMPLOYED PERMITS THE PRODUCTION OF GOOD YIELDS OF Y-TYPE ZEOLITES HAVING A SILICA TO ALUMINA MOLE RATIO OF ABOVE 3.9 UNDER MILDLY ALKALINE CONDITIONS HERETOFORE CONSIDERED POSSIBLE ONLY IN CONJUNCTION WITH SILICA HYDROSOLS AND REACTIVE AMORPHOUS SOLID SILICAS.
