The article presents the main results of methods for modifying natural aluminosilicates (Az-4 and halloisite) with transition metals (Ni, Mo) using a CVD (Chemical Vapor Deposition) setup and physicochemical methods for studying the obtained catalysts. It was found that the elements Mo and Ni in the surface layers of the catalysts obtained as a result of the modification of both natural aluminosilicates by the ion exchange method were more distributed than the elements modified by the impregnation method. During the hydrocracking of fuel oil in the presence of aluminosilicate catalysts, 80-83% of the volume of light oil products (gasoline, diesel fractions) was obtained.
