Description
Summary: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 Cu.sub.0.45Zn.sub.0.15Mg.sub.5.4Al.sub.2O.sub.9 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.
