Three-phase hydrogenation of ?-glucose over a carbon supported ruthenium catalyst—mass transfer and kinetics

Mechanism and Kinetic Analysis of the Hydrogenolysis of Cellulose to Polyols

“…No inhibition by sorbitol or mannitol was observed. The activation energy of glucose hydrogenation over the Ru catalyst was 55 kJ/mol, which is well consistent with the values of ~60 kJ/mol in other studies [106,108,112]. Besides Ru catalysts, Ni catalysts are also extensively considered for glucose hydrogenation.…”

Pyrolysis Oil Stabilisation by Catalytic Hydrotreatment

“…The main focus is on the hydrogenation of D-glucose to Dsorbitol, a well-known chemical with use in the pharmaceutical and the food industry (Kusserow et al, 2003). Catalytic hydrotreatment of D-glucose over Ni, Ru based and Pd based heterogeneous catalysts at 80 °C, 80 bar yields D-sorbitol in high yields (Crezee et al, 2003;Makkee et al, 1985) (Scheme 2). The hydrogenation reactions at these low temperature levels may be considered as the stabilisation step in fast pyrolysis oil upgrading.…”

Influence of the Mesoporous Polymer Matrix Nature on the Formation of Catalytically Active Ruthenium Nanoparticles

“…Now the industrial catalyst for Dglucose hydrogenation is Raney-type Ni [24][25][26]. However, the drawback of Ni catalysts is their tendency to Ni leaching that results not only in the loss of catalytic activity (after five Cat recycles the activity decreases by 40%) but also to the pollution of target product [20].…”

“…The catalysts on the base of ruthenium [24,28] occupy the leading position in the activity among the metals Ru > Ni > Rh > Pd [29] and it simplifies considerably the technology of obtaining D-glucose. Ru nanoparticles supported on mesoporous silicas [30][31][32], porous carbons [25,28,29], zeolite β [33], alumina [26] and others have been reported to be highly active in various reactions.…”
