Combined Hydrothermal Conversion of Biomass (Algae and Aquatic Vegetation) from Lake Baikal Littoral Zone and Heavy-Oil Resids to Produce Biofuel

Resumo

The prodigious growth of filamentous algae that has been occurring since 2011 in the littoral zone of Lake Baikal poses an acute ecological problem. Samples of algal biomass and aqueous vegetation were collected from the littoral zone of Lake Baikal and converted by hydrothermal treatment into biofuel in the presence of ammonium heptamolybdate. It was demonstrated that algal biomass from the Baikal littoral zone could be a potential source of feedstock for producing biofuel by thermocatalytic treatment. The addition of heavy-oil resids to algal and aquatic vegetation biomass increased the motor-fuel yield and modified its composition.
