Comparison of Hydroprocessed Bio-oil and Jet Fuel Fraction Characteristics to ASTM Standards for Drop-In Fuels

摘要

Bio-oil is produced by flash pyrolysis of small biomass particles at 400 to 650o C in the absence of oxygen. The yield of bio-oil is relatively high at 65-75 percent dry-weight basis or higher depending on the production process. Bio-oil chemical properties vary with feedstock type and applied pyrolysis conditions but woody biomass typically produces a mixture of about 30-percent water, 30-percent phenolics, 20-percent aldehydes and ketones, 15-percent alcohols and 10-percent miscellaneous compounds1 .
