Evaluation of D-Glucose Hydrogenation Catalysts Stability in Different Reactor Systems
Authors: , , , , , , ,
Abstract: D-glucose catalytic hydrogenation to D-sorbitol can be considered a promising step in cellulose feedstock transformation technology to fuel components and valuable chemicals. Traditionally D-glucose is hydrogenated in bath reactor systems using Ru, Ni, Pd impregnated over different organic and inorganic supports. The samples of ruthenium impregnated in hypercrosslinked polystyrene and activated carbon were tested in D-glucose hydrogenation using butch reactor, shaker type reactor and fix bed reactor system to evaluate catalysts long term stability. Catalysts were characterized by nitrogen physisorption, X-Ray photoelectron spectroscopy, hydrogen chemisorption, X-Ray fluorescence analysis. Physicochemical changes of the studied catalysts are shown during catalysts stability investigation. A strong influence of the reactor type on catalysts stability in D-glucose hydrogenation is discussed.
