“…Various non-noble monometallic and bimetallic catalysts were reported, such as Raney Co and MgO and ZnO supported Co − Ni Raney and SiO 2 , SiO 2 -Al 2 O 3 , AC, NaZSM-5 supported Ni catalysts, − SBA-15, SiO 2 , MgO, fly ash, Al 2 O 3 , Cr 2 O 3 , AlMCM-41, Al 2 O 4 ZnO-ZnAl 2 O 4 , HMS, HY, H-β, and H-ZSM supported Cu catalysts. − Among all, the supported Cu catalysts have exhibited higher yield to 1,2-PDO. Further, among Cu-based catalysts, higher glycerol conversion (>90%) and 1,2-PDO selectivity (>85%) were obtained over MgO, SBA-15, and Al 2 O 3 -supported Cu catalysts in liquid phase hydrogenolysis of glycerol.…”

In the last two decades, various glycerol value addition techniques have been developed and discussed in the literature. Among all these processes, conversion of glycerol to 1,2-propanediol (1,2-PDO) has been recognized as one of the promising and commercially attractive glycerol value addition routes. This review is an attempt to scan out the progress in catalysts design and development for liquid and vapor phase glycerol hydrogenolysis for the production of 1,2-PDO. The development of supported and mixed metal oxide catalysts with their novel catalytic characteristics for glycerol conversion and 1,2-PDO selectivity has been scrutinized systematically. It was observed that among the nonnoble metal catalysts, Cu-based catalysts have shown promising activity toward 1,2-PDO; however, their stability is an issue. Among noble metals, Pt-and Ru-based catalysts were reported active for glycerol conversion. Comparatively, catalysts composed of Pt, Ru, Pd as a noble metal, and Cu as a non-noble metal have resulted in higher catalytic activity and 1,2-PDO selectivity. This review also summarizes different reaction pathways for hydrogenolysis of glycerol to 1,2-PDO, the effect of additives (solid acid and base), and methods of catalyst preparation on the catalyst performances. Further, glycerol hydrogenolysis with in situ H 2 production by glycerol reforming or by chemical transfer hydrogen using various hydrogen donors and the effect of different solvents on the glycerol hydrogenolysis process are also discussed. Reaction kinetic models are also included at the end.

Glycerol hydrogenolysis to 1,2-propylene glycol in a continuous down-flow fixed-bed reactor with 60 %Cu/Al 2 O 3 catalyst was investigated. The routes of main, intermediate and by-products formation were proposed. It is shown that an increase in the catalyst particle size from 0.1-0.16 to 1.6-2.5 mm transfers the process from the kinetic mode to an intermediate mode between the kinetic and internal diffusion controlled reaction rate. In this case, the observed activation energy decreased by 30 %. The optimal conditions for the process have been determined.

The available experimental material relating to the patterns of formation and properties of functional nanostructured transition metal oxide (Mo, Co, Mn, Ni, Fe, V) composite materials is reviewed. Advanced coatings are considered those whose formation method are simple and do not require high energy costs, expensive equipment and permit the creation of materials with desired physical and chemical properties in a specified manner. In this review, the priority of oxide composite nanostructured materials technology is given to a transient electrolysis method based on the analysis of a data set that demonstrates its advantages. The results are presented for a number of studies aimed at identifying and analyzing the nature and regularities of processes that take place when obtaining oxide composite nanostructured materials using transient electrolysis methods.
