Abstract
This case relates to a process for producing aromatics by contacting a C.sub.3 -C.sub.8 hydrocarbon with a gallium catalyst supported on an aluminosilicate in which the ratio of silica to alumina is between 20:1 and 70:1.
Claims11
A process for producing aromatic hydrocarbons comprising bringing into contact at an elevated temperature a C.sub.3 -C.sub.12 hydrocarbon feedstock with a catalyst composition comprising an aluminosilicate having gallium deposited thereon or an aluminosilicate in which cations have been exchanged with gallium ions, said aluminosilicate having silica to alumina in a molar ratio of between 20:1 and 70:1.
A process according to claim wherein gallium is impregnated on the aluminosilicate support as a compound giving rise to gallium oxide during activation.
