Abstract
Abstract The present invention relates to supported superacidic catalysts comprising C 4 -C 18 , preferentially C 6 to C 12 , perfluorinated alkanesulfonic acid absorbed on suitable supports, such as fluorinated alumina, alumina silica and other chalcides having bonded thereto subsequently a Lewis acid compound selected from the higher valency fluorides of the elements of Groups IIA, IIIA, IVB, VA or VIB of the Periodic Table. The invention includes a process for catalytic transformation of hydrocarbons.
