GALLIUM ENTHALTENDER ALUMINOSILIKAT-KATALYSATOR UND SEINE VERWENDUNG FUER DIE AROMATISIERUNG VON C2-C4-LEICHTEN GASEN.

摘要

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. ……
