Abstract
A process for preparing a synthetic faujasite having a novel platelet-type crystalline shape and a silica to alumina ratio above 2.2 by adding potassium ions to a seeded faujasite synthesis slurry and heating to convert to the synthetic faujasite. The use of the novel zeolite form as a catalyst promoter and an adjuvant for strengthening formed zeolite such as beads, balls, pills and extrudates is also disclosed.
