Hydrodeoxygenation

Hydrodeoxygenation (HDO) is a hydrogenolysis process for removing oxygen from oxygen containing compounds. Typical HDO catalysts commonly are sulfided nickel-molybdenum or cobalt-molybdenum on gamma alumina. An idealized reaction is:[1]

R2O + 2 H2 → H2O + 2 RH

The first review on HDO was published in 1983.[2] HDO is potentially of interest for producing biofuels, which are derived from oxygen-rich precursors like sugars or lipids. Because of high capital and transportation costs, HDO is not commercially feasible for the deoxygenation of biomass-derived feedstocks. Instead, deoxygenation of biomass typically involve dehydration and decarboxylations.[3]
