Product characterization from catalytic liquefaction of empty palm fruit bunch (EPFB) in near and supercritical water

Catalytic performance and suitable biomass to water ratio that supported higher EPFB conversion, liquid hydrocarbons yield and lignin degradations were screened for EPFB liquefaction under subcritical conditions operating at 270oC and 20 bars for 20 minutes. Analytical results indicate that maximum...
