ABSTRACT:
A process of preparing a ferrierite-type zeolite, with high crystallinity rate and having a anhydrous stage composition expressed by the formula M.sub.x (AlO.sub.2).sub.x (SiO.sub.2).sub.y, M being a cation of an alkaline metal such as Na or K, or a mix of both. The process contains a gel-producing step, by addition of boric acid to an aqueous aluminum-sulfate solution mixed with a aqueous solution containing oxides of Na and/or K and of Si, without the use of a structural agent. The invention also pertains to any zeolite obtained by this process, and its uses.
