BioTfueL Technologies�– Why�Torrefaction
� Biomass feedstock preparation:
� Torrefaction
⇒ Improvement of feedstock properties for
� grindability with much lower energy consumption
� fluidization behaviour of milled powder
� pneumatic dense phase transport in Gasification Unit
� storage & transport
� + enhanced energy content
⇒ Moderate process conditions
� [200 – 300°C]
� ≈ atmospheric pressure

BioTfueL project summary
Gasification and Fischer-Tropsch are proven technologies and allow
flexibility towards feedstock
The BioTfueL project combines the strength of 6 companies
The BioTfueL project allows to give full performance guarantees (process
and catalysts) for the complete chain from biomass to diesel & jet fuel
The BioTfueL objectives are to develop, demonstrate and commercialize
a full B-XTL chain
First industrial B-XTL plants will have a capacity of 5.000 bbl/day (200 kt/yr)
in one single train
A unique focal point for customers: Axens
