eng	OXIDATIVE DEHYDROGENATION OF LIGHT HYDROCARBONS ON MCM-36 LAMELLAR ZEOLITE	In this work, we report successful preparation of VOx-MCM-36 catalysts. Lamellar pillared zeolitic support (MCM-36) was prepared from layered precursor of MCM-22 zeolite by swelling and pillaring. Vanadium was introduced into MCM-36 support by different methods (including impregnation and conventional ion exchange) by means of different precursors and synthesis conditions (textural properties of prepared catalysts were characterized by nitrogen adsorption-desorption isotherm, the concentration of vanadium was determined by X-ray fluorescence and vanadium complex speciation was investigated by diffuse reflectance UV-vis spectroscopy, hydrogen temperature programmed reduction (H2-TPR), EPR and FTIR spectroscopy. Effect of synthesis method and conditions on catalytic behavior was tested in the oxidative dehydrogenation of propane and n-butane at 540°C.	catalyst; oxidative dehydrogenation; VOx; zeolite
