Gas-phase maleic anhydride hydrogenation over Ni/SiO2- Al2O3 catalysts: Effect of metal loading
The gas-phase maleic anhydride hydrogenation was studied at 170 °C and 1 bar using Ni/SiO2–Al2O3 catalysts varying metal loading. The maximum γ-butyrolactone selectivity was reached for a 10 wt% nickel load. On the basis of temperature programmed experiments, it is proposed that new active sites in...

| Summary: | The gas-phase maleic anhydride hydrogenation was studied at 170 °C and 1 bar using Ni/SiO2–Al2O3 catalysts varying metal loading. The maximum γ-butyrolactone selectivity was reached for a 10 wt% nickel load. On the basis of temperature programmed experiments, it is proposed that new active sites in selective succinic anhydride hydrogenolysis are formed when Ni loads are higher than 8 wt% |
