The pyrolysis, liquefaction, and gasification of algae for the production of biofuels are summarized. The effect of algal strains and the presence or absence of reducing gases and catalysts under a variety of reaction conditions are discussed. Most of the experiments have been carried out on a small scale (<10 g algae), and product characterization has mainly been restricted to GC-MS. Under appropriate conditions encouraging yields of gaseous and liquid fuels can be obtained. This review does not cover transesterification reactions of algae leading to fatty acid esters including FAMES, other than a few studies which involved pretreatment of the algae.
