Abstract
The object of the invention is a synthetic crystalline zeolite of the mordenite type characterized by: PA0 a) the following approximate general formula: EQU Na.sub.2 O, Al.sub.2 O.sub.3, xSiO.sub.2 PA0 where x is a number ranging from 9 to 30, and PA0 b) an X-ray diffraction diagram represented in table I of the description, PA0 c) a fluorine content ranging from about 0.005 to 2.0% by weight, and in that it has been synthetized in a fluoride medium. The invention also relates to a process for preparing said zeolite. This zeolite can notably be utilized in adsorption and in catalysis.
