     production of bio-oil by microwave-assisted direct liquefaction (madl) of ulva proliferawas investigated, and the bio-oil was analyzed by elementary analysis, fourier transform infrared spectroscopic analysis (ft-ir), and gas chromatography–mass spectrometry (gc–ms). the results indicate that the liquefaction yield is influenced by the microwave power, liquefaction temperature, liquefaction time, catalyst content, solvent-to-feedstock ratio and moisture content. the maximum liquefaction yield of u. prolifera (moisture content of 8%) was 84.81%, which was obtained under microwave power of 600 w for 30 min at 180 °c with solvent-to-feedstock ratio of 16:1 and 6% h2so4. the bio-oil was composed of benzenecarboxylic acid, diethyl phthalate, long-chain fatty acids (c13 to c18), fatty acid methyl esters and water. the results suggest that u. prolifera is a viable eco-friendly, green feedstock substitute for biofuels and chemicals production.
