Abstract

It has been shown that addition of cobalt to a vanadium-phosphorus oxide catalyst increases the P/V molar ratio on the surface, the surface acidity and the selectivity of butane oxidation. It has been established that in the V−P−Co−O catalyst the probability of the removal of phosphorus from the surface is markedly reduced.

Abstract

Показано, что введение кобальта в окисный ванадийфосфорный катализатор повышает поверхностное отношение фосфора к ванадию, кислотность поверхности и селективность окисления бутана. Установлено, что вV−P−Co−O катализаторе значительно уменьшается вероятность уноса фосфора с поверхности.
