STUDY ON PYROLYSIS OF TWO SEAWEEDS BY MICROWAVE HEATING
Biomass has been used as energy source by mankind since ancient times. However, the portion of biomassutilized so far is limited to terrestrial biomass and direct combustion is the main utilization manner. As population onearth is growing fast and terrestrial biomass is becoming more and more limited, a glance at large volume of seaweedsnaturally triggers interest of many researchers. This paper is devoted to a preliminary exploration on how to convertseaweeds(Ulva Rigida and Polysiphonia Urceolata) to second energy carriers via pyrolysis by microwave heating. Theseaweeds devolatile at a relatively low temperature regimes as compared to terrestrial lignocellulosic biomass. Yields ofgaseous product, char, tar and its composition and distribution obtained via pyrolysis of two seaweeds by microwaveheating are quite different from those obtained via pyrolysis of lignocellulosic biomass by microwave heating undercomparable conditions. Specifically, yield of gaseous product from seaweeds is lower as compared to our previous studythough it contains the same main components as that of terrestrial biomass; yield of tar from seaweeds is also lower andits composition is quite different from that of terrestrial biomass. The tar from the seaweeds contains much morenonpolar components, especially chain hydrocarbons from C10-C16, which may be used as high quality liquid fuel.
