Hydrodeoxygenation

Hydrodeoxygenation (HDO) is a hydrogenolysis process removing oxygenated compounds from fast pyrolysis or hydrothermal liquefaction derived bio-oil using commercial hydrotreating catalysts in the form of water.[1]

Hydrotreating catalyst commonly used are nickel-molybdenum or cobalt-molybdenum on gamma alumina, zeolites (ZSM-5), palladium on carbon and platinum on carbon as well as alumina.
