Katalysator mit MFI-Struktur und seine Verwendung zum Aromatisieren von Kohlenwasserstoffen mit 2 bis 12 Kohlenstoffatomen.

摘要

A composite catalyst which contains: - a zeolite of MFI structure containing at least one element chosen from the group consisting of alkali and alkaline-earth metals and containing in its framework at least the elements silicon, aluminium and/or gallium, - a matrix, - at least one noble metal of the platinum group, at least one additional metal chosen from the group consisting of tin, germanium, indium, copper, iron, molybdenum, gallium, thallium, gold, silver, ruthenium, chromium, tungsten and lead, - at least one halogen chosen from the group consisting of fluorine, chlorine, bromine and iodine, - optionally at least one metal chosen from the group consisting of gallium and zinc, - and optionally, preferably in the matrix, at least one element chosen from the group consisting of alkali and alkaline-earth metals. Use of this catalyst in aromatisation reactions of hydrocarbons containing from 2 to 12 carbon atoms per molecule.
