PROCESS FOR THE PRODUCTION OF BIO-OIL FROM PHOTOTROPHIC AND HETEROTROPHIC ALGAE

摘要

A process for the production of bio -oil from phototrophic and heterotrophic algae comprising: cultivating at least one phototrophic alga, under photoautotrophic conditions, in order to obtain a first aqueous suspension of algal biomass; - cultivating at least one heterotrophic alga, under heterotrophic conditions, in order to obtain a second aqueous suspension of algal biomass; - subjecting said first aqueous suspension of algal biomass to concentration in order to obtain a first concentrated aqueous suspension of algal biomass; - combining said first concentrated aqueous suspension of algal biomass with said second aqueous suspension of algal biomass obtaining a third aqueous suspension of algal biomass; - subjecting said third aqueous suspension of algal biomass to concentration in order to obtain a second concentrated aqueous suspension of algal biomass; - subjecting said second concentrated aqueous suspension of algal biomass to thermal treatment in order to obtain an oily phase comprising bio-oil and an aqueous phase comprising organic compounds.
