central composite design using Design Expert software. The 25Ni-15Cu/AlO(OH) catalyst at 6 h was chosen for its high 1,2-PD activity, achieving a high glycerol conversion of 62% with a corresponding 1,2-PD yield of 53.4% (86.0% selectivity of 1,2-PD) under the optimization conditions of 240 °C, 515 psi, and 4.1 wt% catalyst loading, closely aligning with experimental efficiency.
