Abstract

This invention relates to aggregates of small particles of synthetic faujasite zeolite. Small primary particles of zeolite are clustered into larger secondary particles. The observable average width of the primary particles may be 0.3 micron or less and the observable average width of the secondary particles may be 0.8 micron or more. The silica to alumina ratio of the zeolite may be less than 4:1.
