Production of 1,2-propanediol through hydrogenolysis of glycerol over Copper-Chromite is a promising reaction pathway that has large potential markets. However, production is complicated by low catalyst stability and significant difficulty in preventing or removing unwanted reaction byproducts. These unwanted byproducts impart yellow color and foul odor, making the product sell at a much cheaper cost. In collaboration with a commercial partner, the authors investigated an economical way of liquid-liquid extraction for removing these unwanted byproducts. The authors also tried to model the production of MPG over copper chromite catalyst, that involved analysis of the kinetics of the reaction and of the parameter effects on the reaction. Analysis of the impurities and kinetic data gave excellent insights on ways to classify the impurities and ways to remove them. Industrial importance of this hydrogenolysis process and the direction for future research has also been discussed in the current work.
