Method for activation of palladium and platinum catalysts embedded on aluminium fluoride, preferably for isomerization of n-alkanes, petrol light ends, kerosene light and heavy ends and the catalysts activated by this method

摘要

the subject of the invention is a catalytic activation palladium and platinum, embedded in the aluminium fluoride, especially for the isomerisation of n - alkanes, light fraction gasoline, light and heavy fraction oil, characterized by that,that (a) is an acidic palladium or platinum catalyst activation medium bonded to aluminium fluoride by using additional fluorinating measure fluoruju0105cego under flow-through conditions; and then (b) leads to activation of the metal (pd or pt) katalizato ra by reduction with hydrogen or a mixture of hydrogen and inert gas, under flow-through conditions.resulting in an activated catalyst palladowy or platinum on aluminium fluoride (respectively pd / hs - alf3 or pt / hs - alf3) with a large surface area (hs). this catalyst has large specific surface area that is 200 m2 / g, and contains very little? 2 nm nanoparticles of active metal (platinum or palladium) on the surface of the medium fluorkowego.in addition, the invention also includes palladowy or platinum catalysts for aluminium fluoride activated in this way.
