Zusammenfassung:1. A method for producing high-octane gasoline fractions and/or C6-10 aromatic hydrocarbons from hydrocarbon material and/or oxygen-containing organic compounds, comprising preliminary heating of the material in a appropriate heat-exchange equipment, contacting with a catalyst in one or more reactors at an increased temperature and pressure 0.1-4 Mpa, said catalyst comprising zeolite pentacyl, the lattice of which includes aluminum atoms, iron and gallium modified by lanthanum or palladium with subsequent cooling and isolating the contacting products into gaseous and liquid fractions by separating and rectifying in appropriate technological devices and comprises a stage of oxidative regeneration of a catalyst with oxygen-containing gas at increased temperatures, characterized in that the contacting stage is carried out by a catalyst containing zeolite of general empirical formula (0.02-0.3)Na2O Al2O3x(0.01-1.13)Fe2O3x(27-212)SiO2xkH2O, wherein k is a coefficient corresponding to moisture capacity, modified by elements or compounds of I, II, IV, V, VI, VII and VIII groups amounting 0.01-5.05 mass wt %. or zeolite of general empirical formula (0.02-0.3)Na2OxAl2O3x(0.01-0.6)Fe2O3x(0.01-1.0)SigmaEnOmx(28-180)SiO2xkH2O, wherein SigmaEnOm is one or two oxides of elements of II, III, V and VI groups and k is a coefficient corresponding to moisture capacity, amounting 0.01-5.0 mass wt%, zeolite of general empirical formula (0.02-0.3)Na2OxAl2O3x(0.01-0.6)Fe2O3x(0.01-1.0)SigmaEnOmx(28-180)SiO2xkH2O, wherein SigmaEnOm is one or two oxides of elements of I, II, III, IV, V, VI and VII groups and k is a coefficient corresponding to moisture capacity, or zeolite of said composition, modified by elements or compounds of elements of I, II, III, IV, V, VI and VII groups amounting 0.01-5.0 mass wt%, and the catalyst regeneration is carried out at a temperature of 450-540 degree C and pressure 0.3-5% with initial regenerated gas containing 0.3-5wt% of oxygen, and further 15-21 wt% of oxygen. 2. The method according to claim 1, characterized in that contacting the initial material with catalyst is carried out at a temperature of 240-480 degree C. 3. The method according to claim 1and 2, characterized in that contacting the initial material with catalyst is carried out in the presence of hydrogen-containing gas. 4. The method according to any one of claims 1 to 3, characterized in that contacting the initial material with catalyst is carried out in steps in several adiabatic re
