Реферат: Vanadium-alumina and vanadium-magnesia oxidative dehydrogenation catalysts have been investigated by a combination of x-ray phase analysis, differential thermal analysis, and electron microscopy. It has been shown that complex vanadium salts, when deposited on the surface ofγ-Al2O3, are in a highly dispersed, x-ray-amorphous state and do not undergo decomposition at temperatures up to 1000°C. In the vanadium-magnesia catalysts, the active component partially interacts with the support, forming Mg(VO3)2 and V2O4. The phase composition of these systems remains unchanged under the conditions existing in the reaction of oxidative dehydrogenation.
