Focus● The main focus of our research is fast pyrolysis● This is an advanced thermal process that produces up to
75% wt. liquid (bio-oil) from biomass with some byproduct char and gas
● The liquid can be used for:● Power generation in engines and turbines
● Heat in boilers and co-firing
● Chemicals directly or via upgrading and separation
● Energy carrier to reduce handling & storage of biomass
● Biofuels by upgrading
