“…However, due to its comparatively lower commercial value, there is an immediate need for a more viable technological alternative to efficiently utilize glycerol. In fact, glycerol has garnered significant research attention due to its potential for conversion into valuable chemicals, including 1,1-propanol [2], 1,2-propanediol [2], 1,3-propanediol [2], acrolein [3,4], acrylic acid [4][5][6], and lactic acid [7][8][9][10][11][12][13][14][15][16]. Among these products, lactic acid stands out as it has numerous potential applications not only in the realm of organic chemistry but also extent their reach into diverse fields such as bioplastics, pharmaceuticals, cosmetics, detergent, and etc [17,18].…”

The surge in glycerol production from oleochemical industry prompted the aggressive search for new value-added derivatives such as lactic acid. A series of novel Ce1 − xZrxO2 catalysts on mesoporous SBA-15 were synthesized and tested in a 50 mL reactor for up to 2 hours for oxidative lactic acid synthesis from glycerol. A suitable kinetic model to represent the reaction was identified and kinetic parameters were calculated. The 10Ce1 − xZrxO2/SBA-15 catalyst, at a 15 wt.% catalyst-to-glycerol ratio, exhibited impressive activity, achieving 94.2% glycerol conversion and 45.3% lactic acid yield at 260°C. The reaction model shows good agreement with experimental data across various reaction conditions (R2 values between 0.90 and 1.00). Based on a pseudo-second-order kinetic model, the selective conversion of glycerol to lactic acid was found to have an activation energy of 165.3 kJ/mol, with a high R2 value of 0.94 which was lower than some reported results.
