 Extraction of cardanol and phenol from bio-oils obtained through vacuum pyrolysis of biomass using supercritical fluid extractionRajesh N. Patel, Santanu Bandyopadhyay and Anuradda Ganesh Energy, 2011, vol. 36, issue 3, 1535-1542 Abstract: The feasibility of extraction of phenol rich oil from the bio-oils obtained through pyrolysis of cashew nut shells and sugarcane bagasse is studied. The extraction rate of phenol rich oil using CO2 as a supercritical fluid is discussed. Operating parameters are optimized for the maximum concentration of phenol and cardanol. Higher yield of oil (50% by weight) along with higher concentration of phenols and cardanol by present method is found encouraging. The experiments were conducted in the pressure range of 120–300bar, the temperature range of 303–333K and the mass flow rate range of 0.7–1.2kg/h. The process parameters are optimized to maximize the yield of extracts and its contents of phenols and substituted phenols from sugarcane bagasse pyrolysis oil. The oil samples obtained at various operating parameters are analyzed by Gas Chromatograph–Mass Spectroscopy (GC–MS) and Fourier Transform Infra-Red Spectroscopy (FTIR).
