Abstract
A MFI-based gallosilicate type catalyst is described. The catalyst is characterized by the following composition expressed by weight: PA1 a) 0.1 to 99.49% of a matrix, PA1 b) 0.5 to 99.99% of a zeolite having the following approximate chemical formula: EQU M.sub.2/n O, Ga.sub.2 O.sub.3, xSiO.sub.2 PA1 wherein PA2 M represents a proton and/or a metallic cation, PA2 n is the valence of said cation, PA2 x is a number ranging from 12 to 1,00, PA1 the zeolite of MFI structure synthesized in a fluoride medium having a fluorine content ranging from 0.02 to 1.5% by weight incorporated during synthesis. The catalyst is notably used in aromatization reactions of light C.sub.2 -C.sub.4 gases in the presence or not of olefins.
