A catalyst based on an MFI of the gallosilicate type is described. …<??>The catalyst is characterised by the following composition, expressed by weight:… a) 0.01 to 99.49% of a matrix,… b) 0.51 to 99.99% of a zeolite of the following approximate… chemical formula:… M2/nO.Ga2O3xSiO2, 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 zeolite of MFI structure synthesised in a fluoride medium… having a fluorine content of between approximately 0.02 and 1.5%… by weight incorporated during its synthesis. …<??>The catalyst can be employed especially in aromatisation reactions of C2-C4 light gases in the presence or absence of C2-C4 olefins. |
