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 CO 2 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...
This work investigated the extraction of cashew nut shell liquid (CNSL) using supercritical carbon dioxide (SC-CO 2 ). Effects of process parameters such as extraction pressure, temperature and flow rate of SC-CO 2 were investigated. The yield of CNSL increased with increase in pressure, temperature and mass flow rate of SC-CO 2 . However, under different operating conditions,...
Cashew nut shell (CNS) has been studied for the product distribution in a packed bed vacuum pyrolysis unit. The effect of pyrolysis temperatures on the product yields is also studied. The oil-to-liquid ratio in the pyrolysis products was found to remain almost constant in the range between 400 o C and 550 o C. The properties of CNS oil has been found to be amazingly near to that of...
