Abstract: Pure ccrium hydroxide has been prepared by pseudo-template method and sulphate modification has been carried out by wet impregnation method using H2SO4. Modified catalysts have been prepared by incorporating varying amounts of molybdenum (5,10 and 15%) into pure as well as sulphated cerium hydroxide and characterized by XRD, FT-IR, BET surface area and DRS techniques. The acid structural properties have been determined by temperature programmed desorption of ammonia and thermodesorption studies using 2, 6-dimethylpyridine. Study on catalytic activity of the systems towards oxydehydrogenation of ethylbenzene shows the formation of styrene as the major product. Reaction conditions such as air flow, temperature of the reaction and flow rate of ethylbenzene have been optimised.
