Предложен катализатор окисления, имеющий фасонную структуру, содержащий каталитический материал, состоящий из смешанных окислов ванадия и фосфора, пригодный для производства малеинового ангидрида в результате частичного окисления неароматических углеводородов, в частности н-бутана, в паровой фазе молекулярным кислородом или газом, содержащим молекулярный кислород. Катализатор с такой структурой отличается тем, что имеет (а) геометрический объем от примерно 30 процентов до примерно 90 процентов от геометрического объема геометрической формы твердого тела, не содержащей полых пространств, (б) отношение наружной площади геометрической поверхности/геометрическому объему не менее примерно 15 см- 1, (в) объемный вес от примерно 0,4 г/см3 до примерно 1,4 г/см3 и (г) механическую прочность, достаточную для сохранения практически структурной целостности фасонной структуры катализатора при его использовании.An oxidation catalyst is proposed having a shaped structure containing a catalytic material consisting of mixed vanadium and phosphorus oxides, suitable for the production of maleic anhydride as a result of partial oxidation of non-aromatic hydrocarbons, in particular n-butane, in the vapor phase with molecular oxygen or a gas containing molecular oxygen. A catalyst with such a structure is characterized in that it has (a) a geometric volume of from about 30 percent to about 90 percent of the geometric volume of the geometric shape of a solid body that does not contain hollow spaces, (b) the ratio of the external surface area of the geometric surface / geometric volume is not less than about 15 cm - 1 , (c) a bulk density of from about 0.4 g / cm 3 to about 1.4 g / cm 3 and (g) mechanical strength sufficient to maintain the almost structural integrity of the shaped structure of the catalyst when it is used.
