Evaluation of D-glucose Hydrogenation Catalysts Suability in Different Reactor Systems

Abstract

he 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.
