Abstract: A new catalyst for isomerization process of light hydrocarbons based on novel synthesized inorganic superacids has been developed. With this purpose a number of mixed heteropolyanions with a modified Keggin structure containing different transition metals (including platinum group metals) have been synthesized. The technology of preparation of superacid catalysts with a coating of mo-dified heteropolycomplexes on different carriers has been developed. Lewi acid characteristics of the developed superacid catalysts on different car- riers have been investigated
