Abstract
An aluminosilicate type catalyst and its use in the aromatization of a C.sub.2 -C.sub.4 light-gas cut in the presence or not of olefins is described. The catalyst is characterized by the following composition expressed by weight: PA0 a) 0.01 to 10% by weight of gallium PA0 b) 0.1 to 99.49% of a matrix PA0 c) 0.5 to 99.99% of a zeolite having the following approximate chemical formula: EQU M.sub.2/n O, Al.sub.2 O.sub.3, xSiO.sub.2 wherein PA1 M represents a proton and/or a metallic cation, PA1 n is the valency of said cation, PA1 x is a number ranging from 12 to 1000, PA0 said zeolite having a MFI structure being synthesized, moreover, in a fluoride medium and having a fluorine content ranging from 0.02 to 1.5% by weight incorporated during synthesis.
