Microalgae pyrolysis

Two moss samples (Polytrichum commune, Thuidium tamariscinum), one alga sample (Cladophora fracta), and one microalga sample (Chlorella protothecoides) were subjected to pyrolysis and steam gasification for producing hydrogen-rich gas (Demirbas, unpublished work). 

The HHVs for bio-oils from mosses 21.5-24.8 MJ/kg and the HHVs for biooils from alga and microalga 32.5 and 39.7 MJ/kg, respectively, were obtained by pyrolysis at temperatures ranging from 775 to 825 K. In general, algae bio-oils are higher quality than bio-oils from mosses.

With the exception of some minor contributions by microalgae, bacteria (reviews by Zobell, 1971 Zitko, 1975) and plants (Hancock et al., 1970), aromatic hydrocarbons are not synthesised by organisms (Grimmer and Duevel, 1970). They are generally considered as products of pyrolysis at high...
