Aluminosilikat Katalysator und seine Verwendung zum Aromatisieren von 2 bis 12 Kohlenstoffatome haltende Kohlenwasserstoffen.

摘要

Composite catalyst which contains: - a zeolite of MFI structure in hydrogen form, 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 doping element chosen from the group consisting of gallium and zinc, - and optionally 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 4 to 12 carbon atoms per molecule.
