Reaction Pathways for the Deoxygenation of BiomassderivedrnFurfural over Different Metal Catalysts (Cu, Pd,rnand Ni)

摘要

Furfural is one of the numerous oxygenated compoundsncommonly found in bio-oil. Due to their high reactivity, thesencompounds need to be catalytically deoxygenated to improve bio-oilnstorage stability, boiling point range, and water solubility. Dumesicnet al. have proposed that aldol condensation of furfural with smallnketones is a promising approach to produce higher alkanes (C8–C15)nfor diesel fuel. They have obtained high yields of condensationnproducts by direct condensation of furfural with acetone in thenpresence of basic catalysts. An alternative route to increase thenstability of oxygenated compounds is the selectivenhydrodeoxygenation under mild conditions, which may result innproducts that have value as gasoline components or gasolinenadditives. For instance 2-methyl furan, could be a suitable option tonbe used as an octane booster (RON = 131). Within this context, thengoal of this contribution is to compare the conversion of furfural overndifferent silica-supported metals. Copper, palladium, bimetallicnpalladium-copper, and nickel catalysts have been selected to studyntheir activity, selectivity, and possible reaction pathways
