"Bioglycerol is the by-product which is produced largely from the microbial fermentation, hydrogenolysis of glucose in the mixture of polyols, fatty ester, soap manufacturing process and fatty acid production. Hydrogenolysis of glycerol is one of the most promising ways to convert glycerol and many work has been done towards 1,3-propanediol, 1,2-propanediol and 1-propanol using various metals and mixed-metal oxides such as W, Ru, Rh, Pt, Pd, Cu, Ni and different zeolites have been extensively used as the active components.

It has been well documented that the presence of Bronsted acid sites leads to the formation of acrolein, while Lewis acid sites, and even basic catalysts, gives rise to hydroxyacetone as the main product. However, there is little research on the use of H-Beta zeolite as the catalyst and metals support for hydrogenolysis of glycerol.

The investigations conducted in this study consist of the development of active catalysts as well as optimize process conditions, in the dehydration of glycerol to value-added chemicals. The use of different H2 pressures above 600-1200 psi, reaction temperatures 180-220 ⁰C, reaction times (5-10 h), and the optimum catalyst/reactant ratios leads to significant impact of the liquid-phase reactions and the formation of products.

Various bi-metallic catalysts based on W, Cu, Ni, Sr, Zr and Zn are studied with regard to the dependence of activity and stability in hydrogenolysis of glycerol with H-Beta zeolite support. All prepared catalysts are characterized using various analysis techniques such as N2 sorption, XRD, FTIR, and NH3-TPD and the obtained organic products are then further analyzed with the help of GC-FID and GC-MS"--Abstract, page iii.
