A catalyst of the aluminosilicate type and its use in aromatisation of a C2-C4 light gas cut in the presence or absence of olefins are described. The catalyst is characterised by the following composition, expressed by weight: a) 0.01 to 10% by weight of gallium b) 0.1 to 99.49% of a matrix c) 0.5 t...

Zusammenfassung:	A catalyst of the aluminosilicate type and its use in aromatisation of a C2-C4 light gas cut in the presence or absence of olefins are described. The catalyst is characterised by the following composition, expressed by weight: a) 0.01 to 10% by weight of gallium b) 0.1 to 99.49% of a matrix c) 0.5 to 99.99% of a zeolite of the following approximate chemical formula: M2/nO.Al2O3.xSiO2, where M denotes a proton and/or a metal cation, n is the valency of the said cation, x is a number between 12 and 1000, the said zeolite having an MFI structure being additionally synthesised in a fluoride medium and having a fluorine content of between 0.02 and 1.5% by weight incorporated during the synthesis.
