Abstract

A 1.8 L Parr 4570 high temperature high pressure reactor was used to convert corn cobs into bio-oil via hydrothermal pyrolysis. In order to determine the optimal condition, the effects of operating temperature, retention time and biomass to total reactant ratio on oil yield were investigated. The highest oil yield of 23.7% (of total biomass) was obtained at 305 °C20 minutes retention time, and 10% biomass loading. The effect of crude glycerol on oil yield and quality was also studied. When the glycerol ratio (glycerol to glycerol and biomass) increased from 0 to 80%, oil yield increased from 23.7% to 59.2%. Moreover, the oil quality was improved by adding crude glycerol. No oil was produced when the glycerol ratio was 100%, which implied that crude glycerol without biomass cannot produce oil.
