Sorbitol Hydrogenolysis Over Ni, Pt and Ru Supported on NaY

Abstract

The hydrogenolysis of sorbitol into 1,2-propanediol (PD), ethylene glycol (EG) and glycerol (G) was investigated over Ni, Pt and Ru supported on NaY at 220°C and 60 bar in a batch reactor. Ni(6 %)-NaY was investigated in detail at different process conditions, including its recyclability. Attempts have been made to rationalize the experimentally observed conversion and product selectivity obtained over the different catalysts with results of Density Functional Theory calculations of adsorption energy and bond length changes in sorbitol adsorbed over various planes of Ni, Pt and Ru.

Conversion of Cellulose and Cellobiose into Sorbitol Catalyzed by Ruthenium Supported on a Polyoxometalate/Metal–Organic Framework Hybrid

“…Sorbitol is widely used as a sweetener, a moisture controller in cosmetics, and in medical applications. [36,37] A historical retrospect of the progress of hydrolytic hydrogenation of cellulose into sorbitol reveals that most of the catalytic systems used share two main components (Scheme 1): 1) a transition-metal catalyst (often Pt or Ru) and 2) a dilute acid or a solid support with sufficient acidity (e.g., oxidized carbon, silica-alumina, or acidic zeolites).

“…It also has been studied as a resource for the production of hydrogen, [33] alkanes, [34,35] and value-added chemicals.

[21][22][23][24][25][26][27][28] A good balance between the two catalytic functions is a necessity.…”

Cu/C‐catalyzed Hydrogenolysis of Sorbitol to Glycols–On the Influence of Particle Size and Base

“…Banu et al. investigated the conversion of sorbitol over Ru‐, Pt‐ and Ni‐NaY catalysts in the presence of base . Ni‐NaY showed the best results with over 60 % conversion and 70 % selectivity to glycols.…”

Exceptional performance of bimetallic Pt1Cu3/TiO2 nanocatalysts for oxidation of gluconic acid and glucose with O2 to glucaric acid

“…In previous work, oxidation of glucose to gluconic acid has been investigated using supported Pt, Pd, and Au catalysts [8,[11][12][13] or their combinations, such as PtPd, PdAu, PtPdBi, PtAu, PtBi, and PdTe [14][15][16][17][18][19][20][21][22][23][24][25]. Although reasonable oxidation activity (TOF = 48-1423 h À1 based on surface metal composition, 45-70°C) was achieved, reported glucose to glucaric acid yields are very low (Y $ 3%).…”
