The effect of rhenium on the conversion of glycerol to mono-alcohols over nickel catalysts under continuous flow conditions

Abstract: Incorporation of Re in supported Ni catalysts greatly improves hydrogenolysis of glycerol to mono-alcohols via increased acidity, dispersion and metal–support interaction.

“…The catalyst exhibited an excellent selectivity to propanols (98%) with full glycerol conversion at 230 °C, but the catalyst deactivated rapidly after the reaction for only 10 h, possibly because of the leaching of acid sites . Besides, Ni/Al 2 O 3 and Ni/SiO 2 catalysts, Re-NiAl 2 O 3 catalyst, graphite material-supported Ru catalyst, Ru complex catalysts, and so forth have also been employed for the catalytic hydrogenolysis of glycerol to propanol. In spite of the various efforts made earlier, it is highly desirable to develop a more efficient catalytic system in order to meet the practical demands of propanol production in terms of its selectivity, catalyst stability, and mild reaction conditions.…”

“…On the other hand, many studies on glycerol hydrogenolysis have been normally performed by using autoclave batch reactors, which would limit the space time yield of the desired products. ,, As we have known, the continuous-flow fixed-bed reactor is a preferable reactor for heterogeneous catalysis where the products can be produced continuously. Sequential two-layer catalysts consisting of H-β and Ni/Al 2 O 3 were applied to glycerol hydrogenolysis, and 69% selectivity to 1-PO was achieved with full glycerol conversion .…”

“…Ni/Al 2 O 3 and Ni/SiO 2 ) for glycerol conversion to 1,2-PDO under continuous flow conditions. 138 Fig. 10 shows that the addition of Re species to the monometallic Ni-based catalysts can enhance the glycerol conversion dramatically, approximately three to four times higher than that of the monometallic Ni/Al 2 O 3 and Ni/SiO 2 catalysts, respectively.…”

“…At the same time, it was found that Cu/ γ ‐Al 2 O 3 (100 % glycerol conversion and 36.5 % acetol selectivity) had better performance compared to Ni/ γ ‐Al 2 O 3 (10 % glycerol conversion and 52.6 % acetol selectivity) and bimetallic Ni‐Cu /γ ‐Al 2 O 3 catalysts (98.5 % glycerol conversion and 5.7 % acetol selectivity) in the formation of acetol because C–C cleavage is facilitated by the Ni‐based catalyst 57, which led to the formation of more gaseous products and low efficiency towards acetol 58.…”
