Several oxygenated compounds were found in the EFB biooil such as acetic acid, phenol and derivations of phenol, aldehydes, ketones and a small percentage of polyaromatic hydrocarbons. Wu and Liu (2010) selected m-cresol (C7H8O) as a model compound of biooil in steam reforming for hydrogen production. Xie et al. (2011) chose methanol, acetic acid, and ethylene glycol for the thermodynamic analysis in aqueous phase reforming of biooil. Ashcraft et al. (2012) defined biooil and pyrolysis gas properties using phenol and ethylene as the respective model compounds to determine the temperature-dependent thermal conductivity, viscosity, and heat capacity.
