Biofuel Production from Algae, Wood Waste, and Grape Marc: A Comparative Study

D.J.N. Subagyono, M. Marshall, W.R. Jackson & A.L. Chaffee
Biofuel prodution from two marine algae, wood waste and grape marc via high temperature high pressure reactions has been studied. The yields and composition of the product obtained from liquefactions with various reactant gases (with or without catalyst) at different temperatures, gas pressures and water to biomass ratios were compared. Thermo-chemical reactions of algae produced significantly higher dichloromethane solubles and generally higher conversion to oil and asphaltene than wood waste and grape marc under the...
