Production of Bio-oil from Fast Pyrolysis of Macroalgae Enteromorpha prolifera Powder in a Free-fall Reactor.

The use of non-food biomass for bio-oils production appears to be an important trend for renewable energy in China. Biomass, in the form of marine macro-algae, is becoming popular among new renewable energy sources. Fast pyrolysis is one of the most important thermal conversion processes from biomass to bio-fuel. In this work, the marine green tide macroalgaeEnteromorpha proliferawas converted into bio-oil by fast pyrolysis in a free-fall reactor at different temperatures ranging from 100 to 750°C. The bio-oil obtained was analyzed by elemental, gas chromatography-mass spectrometer, and Fourier transform infrared spectroscopy analysis. The results showed that the average heat value was 25.33 MJ kg−1and the oxygen content was 30.27 wt%. The results suggested thatE. proliferapresents as a good bio-oil feedstock candidate.
