The conversion of product gas from thermal gasification into FT- (Fischer-Tropsch) fuels for transportation applications is the focal point of this field of activity.

BEST works on the continuous development and market implementation of FT-synthesis for 2nd generation biofuels.

Within Fischer Tropsch synthesis, the product gas, after the removal of catalyst poisons, is converted by a catalytic process at 200-300°C and under pressure into the Fischer Tropsch raw product, which is then upgraded to gain a higher energy content. With a test rig of a capacity of 5 kg/day, parameter variations and catalyst screening are carried out. The FT-raw product is analysed and further upgraded (partial hydro-treating) to the final FT-diesel.

The knowledge obtained from these fundamental research is used to design and build a pilot plant with a capacity of about 1 barrel/day. With this infrastructure it will be possible to product amounts of FT-fuels that can be used for engine tests.
