This study is aimed to compare Cu–Al–Zn catalysts prepared by different methods and their effectiveness in glycerol hydrogenolysis to 1,2-propanediol. The preparation methods were: co-precipitation and thermal decomposition of hydrotalcite, co-precipitation by KOH and thermal decomposition of the precipitate, sol–gel auto-combustion method, oxalate–gel co–precipitation and thermal decomposition of the precipitate and finally, mechanical mixing of Cu, Zn, Al oxides. It was found that the… 


Glycerol Hydrogenolysis to 1,2-Propanediol by Cu/ZnO/Al2O3 Catalysts
The effect of preparation methods on the Cu/ZnO/Al2O3 catalyst structure and catalytic activity on liquid glycerol hydrogenolysis to 1,2-propanediol has been investigated. The physicochemical
Catalytic hydrogenolysis of biodiesel derived glycerol to 1,2-propanediol over Cu–MgO catalysts
Selective hydrogenolysis of glycerol to 1,2-propanediol over Cu–MgO catalysts is reported. A series of Cu–MgO catalysts with varying Cu content were prepared by a co-precipitation method. The
Conversion of Glycerol into Value-Added Products Over Cu–Ni Catalyst Supported on γ-Al2O3 and Activated Carbon
Abstract A series of Cu, Ni monometallic and bimetallic catalysts supported on γ-Al2O3 and activated carbon were synthesized by incipient wetness impregnation method and examined for hydrogenolysis
Hydrogenolysis of Glycerol over Cu/ZnO-Based Catalysts: Influence of Transport Phenomena Using the Madon–Boudart Criterion
Batch hydrogenolysis of concentrated glycerol has been conducted over different Cu/ZnO-based catalysts prepared by the coprecipitation method. The catalysts were characterized by X-ray diffraction,
Synthesis of 1,2-propanediol through glycerol hydrogenolysis on Cu–Al mixed oxides
Cu–Al mixed oxides derived from hydrotalcite-like precursors having an atomic ratio of 3:1 and calcined at 300, 400, and 500 °C were synthesized. The samples were further reduced under hydrogen
Copper-containing mixed metal oxides derived from layered precursors: control of their compositions and catalytic properties
In this article, a series of Cu-containing mixed metal oxides were obtained by calcination of layered double hydroxides (LDHs) precursors with Cu/Zn/Al atomic ratios ranging from 1:3:1 to 3:1:1 in
