Abstract

A process for preparing a synthetic ferrierite having the absorption and catalytic properties characteristic of 5 to 8 angstrom zeolites which comprises treating a reaction mixture consisting of strontium, calcium and/or sodium, lithium or magnesium salts, a source of silica and a source of alumina and water with natural or synthetic ferrierite seeds and heating to convert the mass to the synthetic ferrierite.
