| 发明名称 | Spinel structured catalyst for aldehyde production | ||
| 摘要 | The present invention refers to a catalyst for aldehyde production, in particular formaldehyde or acetaldehyde production, through selective oxidation of alkanol, especially methanol or ethanol, with oxygen, said catalyst having a spinel structure. The catalyst typically comprises a Fea+qVb+xMoc+yΔzO4 spinel structure wherein Δ is an optional cation vacancy and wherein z=3−q−x−y and q×a+x×b+y×c=8 in concentrations corresponding to 0.6<q<3, 0≦x<1.5, 0≦y≦1 and 0≦z<1.3 and 2≦a≦3, 3≦b≦5 and 3≦c≦6. The present invention further refers to a process for producing said catalyst and to the use of said catalyst for selective oxidation of alkanol, preferably methanol or ethanol, with oxygen to aldehyde, preferably formaldehyde or acetaldehyde. | ||
