Microwave-assisted pyrolysis of seaweed biomass was conducted using a microwave pyrolysis system. The product yields were determined and the components of bio-oil were analyzed by a gas chromatography-mass spectrometry (GC-MS). Results showed that as the pyrolysis temperature increased from 400 °C to 600 °C, the gas yield increased and the bio-char yield decreased. However, the bio-oil yield rose firstly and then reduced. The maximal bio-oil yield was 18.4 wt.% when pyrolysis temperature was 500 °C. The bio-oil obtained is a mixture of very complex organic compounds, mainly consisting of aldehydes, ketones, alcohols, esters, phenols, aliphatic hydrocarbons, aromatic hydrocarbons and nitrogencontaining compounds. The relative content of aromatics in bio-oil accounted for about 16%. The above results reveal that microwave-assisted pyrolysis of seaweed biomass is a feasible method to produce aromatics-containing bio-oil.
