Kinetic model for the formation of 1,2-propanediol via liquid-phase glycerol hydrogenolysis was developed in presence of a layered double hydroxide (LDH) precursor derived Cu0.45Zn0.15Mg5.4Al2O9 catalyst. A new reaction pathway of glycerol hydrogenolysis is proposed. The experimental concentrations of feed and products were fitted in the Langmuir–Hinshelwood–Hougen–Watson (LHHW) model. The model equations were solved by ode23s in MATLAB. The kinetic variables were estimated by minimizing the residual sum of squares between the experimental and model-predicted concentrations of feed and products. Results suggested that the LHHW model satisfactorily correlated with the experimental data.
