Catalytic Hydrothermal Processing of Microalgae with Integrated Nutrient Recycling

A.B. Ross, P. Biller & C. Hall
Catalytic hydrothermal processing of microalgae in the presence of heterogeneous catalysts is an alternative route for the production of next generation biofuels and has benefits in terms of energy consumption for high moisture feedstock. The bio-oil generated has a typical heating value of 36 MJ/kg and a typical oil yield of 40% on a dry ash free basis. About 50% of the total algal mass is fractionated in the process water; typically it contains high...
