| titleOfInvention | A kind of nickel-cobalt-aluminum ternary metal composite catalyst and its preparation method and application |
| abstract | The invention discloses a nickel-cobalt-aluminum ternary metal composite catalyst and its preparation method and application. The Ni-Co-Al composite ternary metal catalyst is formed by urea hydrolysis co-precipitation method and then calcined and reduced. The catalyst is marked as xNiyCoAl, wherein x represents the molar ratio of nickel element to Al element, x=1.5-2.5, y represents the molar ratio of Co element to Al element, y=0.25-2. The catalyst can efficiently catalyze the hydrogenation of levulinic acid to synthesize γ-valerolactone in 1,4-dioxane under mild reaction conditions. The catalyst has high catalytic activity, and the yield of γ-valerolactone can reach 100% under the catalytic reaction conditions of 120-130°C and 3-4MPa H 2 for 2-3h; while other reported non-precious metal catalysts usually A similar catalytic effect can be achieved at a reaction temperature of 140-200°C. |
