| 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 Feaq+Vb+Moc+y+ΔzO4 spinel structure whereinΔis an optional cation vacancy and wherein 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. |
