In this work, the extraction of bio-oil using supercritical carbon dioxide (sc-CO2) with particular interest in apparent solubility of phenol (a major chemical compound in pyrolysis oil) was evaluated at various temperatures (50, 60 and 70 °C) and pressures (30, 35 and 40 MPa). Highest extraction yield of bio-oil was obtained at 70 °C and 40 MPa. The phenol content in the extracted bio-oils were also studied and reported. As a preliminary study, the apparent solubility data of phenol in sc-CO2 was successfully modeled using the values from the correlation of Chrastil, Adachi & Lu and Bartle models. The model parameters for these equations were determined and reported in this work. It was found that Chrastil, Adachi & Lu and Bartle models produced satisfactory correlations on the solubility of phenol in sc-CO2, with AARD values of 1.51, 6.52 and 1.85, respectively. © 2018 Elsevier Ltd date: 2018 publisher: Elsevier Ltd official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85048734180&doi=10.1016%2fj.biombioe.2018.06.009&partnerID=40&md5=403c9e77cecbd3c51f63903f6ebf488f id_number: 10.1016/j.biombioe.2018.06.009 full_text_status: none publication: Biomass and Bioenergy volume: 116 pagerange: 106-112 refereed: TRUE issn: 09619534 citation: Chan, Y.H. and Yusup, S. and Quitain, A.T. and Chai, Y.H. and Uemura, Y. and Loh, S.K.
