Catalyst of the galloaluminosilicate type containing gallium, a nobel metal of the platinum family and at least on additional metal, and its use in the aromatization of hydrocarbons

A process for aromatization of hydrocarbons, comprising subjecting a hydrocarbon feed to aromatization conditions in the presence of a catalyst, wherein the catalyst comprises:

• from 1-99% by weight of an MFI zeolite in hydrogen form, the framework of which contains silicon and at least one of aluminum or gallium,
• a matrix,
• a catalytically effective amount of gallium,
• a catalytically effective amount of at least one noble metal of the platinum family, and
• a catalytically effective amount of at least one additional metal which is tin, germanium, indium, lead, gallium, thallium, a Group VIII metal, copper, gold, silver, or a Group VI metal,
• and wherein said catalyst is prepared by a process comprising mixing the zeolite with the matrix and structuring the zeolite and matrix, then depositing the metals and gallium and calcining to produce the catalyst.
