| 摘要 |
The invention relates to a method for hydrogenation of carbonyl compounds, in particular C4-dicarboxylic acids for producing mixtures of tetrahydrofuranne and gamma-butyrolactone on supported rhenium-containing catalysts. Said catalysts are characterised in that rhenium and at least another metal of groups VIII or Ib of the Periodic table of elements, in particular ruthenium (Ru), rhodium (Rh), palladium (Pd), osmium (Os), iridium (Ir), platinum (Pt), copper (Cu), silver (Ag) or cobalt (Co) in the form of at least one bimetallic precursor compound are applied to the support. The inventive catalysts are also disclosed.
