In　order　to　explore　technologies　for　rapid　and　cost-efficient　bio-oil　production　from　algae,　the　authors＇　research　group　has　developed　a　whole　set　of　new　process　for　algae　variety　selection,　culture,　harvest　and　dehydration.　Based　on　the　previous　technical　breakthrough　by　the　research　group　in　microwave　assisted　pyrolysis　(MAP)　of　biomass,　the　optimized　algae　harvested　from　self-cultivated　tank　was　dehydrated　and　used　to　conduct　experiments　on　MAP　of　algae　to　produce　bio-oil　using　self-developed　equipment　for　microwave　assisted　pyrolysis　of　corn　stover.　Some　algae-based　bio-oil　with　water-oil　two-phase　stratification　under　natural　conditions　was　obtained.　The　two-phase　bio-oil　products　were　then　analyzed　to　acquire　their　compositions　using　Gas　Chromatography-Mass　Spectrometry　(GC-MS);　the　compositions　and　their　percentages　were　acquired,　which　can　provide　theoretical　basis　for　refining　algae-based　bio-oil　products　for　various　usages　and　developing　value-added　by-products.　The　research　results　show　that　MAP　of　algae　is　a　rapid,　cost-competitive　and　efficient　method　for　producing　bio-oil,　which　provides　reference　for　mass　production　of　bio-oil　from　algae.
