Abstract
The invention relates to a novel process for the synthesis of zeolites of the ferrisilicate type called ferrizeosilites, to the products obtained by this process as well as their uses. Ferrizeosilite according to the invention is characterized by (a) a chemical formula close to the following: EQU M.sub.2/n O, Fe.sub.2 O.sub.3, x SiO.sub.2 where PA0 M represents a proton and/or a metal cation PA0 n is the valence of said cation PA0 x is a number between 40 and 1000 (b) an x-ray diffraction diagram, and (c) a fluorine content between about 0.01% and 16% by weight. Uses are in processes for the conversion of methanol into hydrocarbons, alkylation of toluene with methanol and catalytic cracking of hydrocarbons.
