CATALYST AND METHOD FOR PRODUCING MALEIC ANHYDRIDE |
摘要 |
<p>The invention relates to a catalyst for producing maleic anhydride by the heterogeneous catalytic gas phase oxidation of a hydrocarbon having at least four carbon atoms. Said catalyst comprises a catalytically active mass containing vanadium, phosphorous and oxygen and has an essentially hollow-cylindrical structure with an outside diameter d1 and a diameter of the opening d2 that passes through said structure. The hollow cylindrical catalyst particles have a geometric density dp according to formula (I), in which parameter alpha equals 2.0 and parameter beta equals 0.3. The invention also relates to a method for producing maleic anhydride on this catalyst.</p> |
