Abstract
Hydrogenolysis of 10% aqueous solution of glucose into propylene glycol on supported Cu-containing oxides has been studied according to target reaction C6H12O6 + 4H2 = 2C3H8O2 + 2H2O in a flow mode. It is shown that the best propylene glycol productivity (0.9 mmol C3H8O2/(gcat·h)) achieves on 23Cu-1Cr2O3/Al2O3 catalyst at 180°C, 4.0 MPa H2 under a catalyst load of 1.6 mmol C6H12O6/(gcat·h). Is is found that ethylene glycol, hydroxyacetone, erythritol, glycerol, 1,2-butanediol, 1,2,4-butanetriol, and sorbitol are side products of the reaction.
