Selective hydrogenolysis of glycerol to propylene glycol using heterogeneous catalysts

Abstract: Glycerol obtained in a large percentage as by-product in bio-diesel production can be hydrogenated to propylene glycol using copper and nickel catalyst compositions. Catalyst compositions were prepared by mechanical mixing of a nickel catalyst with a copper chromite catalyst and by impregnation. The effect of Ni/Cu mass ratio contained in catalyst compositions was evaluated.

“…This can be responsible for the drop of the selectivity to 1,2-PDO at a higher dosage ([100 mg) of Ru/SiO 2 . This excessive hydrogenolysis phenomenon is well known in the hydrogenation of polyhydroxy compounds [10][11][12][13][14][15][16]. It is worth noting that when 100 mg of Ru/SiO 2 was used, the yield of 1,2-PDO was high up to 82.1%.…”

“…In addition, Ni was also able to be used as a dopant or a support. For example, it was revealed that the presence of the metallic Ni in Cu-Cr catalyst helped to increase the selectivity to 1,2-propanediol (188). Recently, Anand et al (189) described the hydrogenolysis of dilute glycerol solution to 1,2-propanediol in the presence of a heterogeneous FeCo(CH 3 C 6 H 2 (CH) 2 O(CH 2 ) 3 N 2 ) 2 /Raney Ni catalyst in which the heterodinuclear FeCo macrocyclic complex and Raney Ni species were probably bound together through ionic bonding.…”

“…Entre los procesos mencionados se destaca la reducción selectiva de glicerol a 1,2-PD o propilenglicol (PG) y etilenglicol (EG) [3][4][5][6][7][8]. Ambos glicoles actualmente se obtienen de derivados del petróleo como propileno y etileno y son materias primas importantes utilizadas sobre todo en la producción de intermediarios como resinas no saturadas y epoxi; el 1,2-PD es además empleado en humectantes, anticongelantes y resinas de poliéster.…”

“…Esta reacción también ha sido estudiada utilizando catalizadores, como Ru/C, Pt/C, Ni/C, cromita de cobre, Ni/Sílice-Alúmina [9]. Catalizadores de metales nobles como Ru, Rh y Pt se emplean para dicha reacción de reducción selectiva en fase líquida [3][4][5][6]. Pt soportado sobre sílice-alúmina amorfa alcanzó 19% de conversión de glicerol y 32% de selectividad a PG, luego de 24 horas de reacción a 220ºC y 45 bars de presión de H 2 [5].…”
