Effect of pyrolysis temperature on the chemical composition of biooils obtained from microalgae biomass

摘要

Algal biomass was pyrolyzed at 450 and 550 degrees C to biooils, H2O, water-sol. org. compds., gases, and biochar. The increase in the pyrolysis temp. resulted in an increase in the combustion heat and C content in the biooil. The biooil quality was detd. by elemental anal., gel permeation chromatog. and IR spectroscopy. The microalgae-derived biooils were addnl. compared with a fossil oil and biooils made by pyrolysis of lignocellulosic biomass.
