Estimating the term…
A Raney copper catalyst, a preparation method and use thereof are provided. The Raney copper catalyst includes aluminum, copper and a metal promoter, wherein the metal promoter comprises a combination of one or more of Ni, Fe, Mo, Co, Ag, Pd, Pt, Au and other elements. The preparation method includes performing high-temperature melting on a mixture containing a copper/aluminum alloy and the metal promoter to obtain a mixed metal cured compound, then smashing the mixed metal cured compound to obtain a catalyst precursor, and subsequently activating to obtain the Raney copper catalyst. The Raney copper catalyst exhibits a capability on hydrogenation reaction based on synergistic effects between metal copper and different promoter metals. Compared with the Raney copper catalyst without metal promoters, when used for preparing 1,3-propanediol through hydrogenation of 3-hydroxypropionaldehyde aqueous solution, the Raney copper catalyst is higher in activity and better in stability.
A Raney copper catalyst, comprising aluminum, copper and a metal promoter, wherein the Raney copper catalyst has a particle size of 0.1-5 mm, and wherein the metal promoter comprises a precious metal promoter and/or a non-precious metal promoter, the non-precious metal promoter comprises one or a combination of more than two of Ni, Fe, Mo and Co, and the precious metal promoter comprises one or a combination of more than two of Ag, Pd, Pt and Au.
