Abstract

A catalyst is prepared by vaporizing aluminium chloride or bromide on to a previously prepared carrier consisting of a refractory oxide, such as silica, alumina, titanium dioxide, zirconium dioxide, chromia, zinc oxide or a naturally occurring form, and a metal selected from Groups VIa or VIII of Mendeleev's Periodic Classification of Elements; and heating the carrier to above 300 DEG C., preferably 400-600 DEG C., to remove any unreacted aluminium halide. The refractory oxide can be synthetically prepared gamma alumina and it can contain 0.01% to 8% combined halogen, preferably fluorine, and the metal, for example, Cr, Mo, W, Fe, Co, Ni, Ru, Rh, Pd, Os, Ir, Pr, is composited with the refractory oxide by drying or precipitation or other known methods. Platinum in the form of an ammoniacal solution of chloro platinic acid can be admixed with alumina and dried, or it can be precipitated by hydrogen sulphide from chloroplatinic acid and an alumina-gel slurry to give a concentration of 0.01% to 2%, by weight, of platinum. Aluminium chloride or aluminium bromide is vaporized or sublimed on to the composite in the form of pellets or irregularly shaped particles. The vaporization can be carried out under pressure, or in the presence of diluents, such as inert gases including paraffin hydrocarbons, hydrogen and nitrogen, and a reaction is indicated by the evolution of hydrogen chloride. Subsequent heating at above 300 DEG C. results in either (a) the removal of the unreacted aluminium chloride, or (b) an additional reaction of the sublimed aluminium chloride as evidenced by the further evolution of hydrogen chloride. In the preferred embodiment whereby aluminium chloride is sublimed on to a platinum-alumina composite the temperature of composite during sublimation and the temperature of the composite during the subsequent heating, is the same. For example, 112.1 grams of platinum-alumina composite in a vertical furnace at 600 DEG C. was connected to 45 grams of heated anhydrous aluminium chloride for 3.5 hours until aluminium chloride vapour appeared at the top of the furnace. The composite, after cooling, was found to have gained 6.7 grams in weight per hundred grams of composite.
