8 FT lab scale plant In operation since 2005 FT raw product 5-10kg/day of FT raw product Slurry reactor, because of excellent heat transfer and easy scaling up Gas treatment removes Sulphur to below 10ppb Cobalt and Iron- based catalyst were tested Fully automatic 9

9 ASF MODEL AND CORRECTED PRODUCT DISTRIBUTION Experimental data for input in simulation of M&E balances W n n(1 ) 2 n 1 log W n n n log( ) log (1 ) 2

10 Long time experience 11

11 Scaling up to 1 bpd 5 liters per day in operation 1 barrel per day In commissioning Smaller Cold Flow Model (100 mm inner diameter Ø) Design for the larger Cold Flow Model (300 mm Ø) Hot Reactor and Pilot Plant Scaled-up Plant for 1 bpd Folie 12

12 Work planed in the project Economic optimisation of gas treatment Scaling up of Slurry FT reactor Long term tests of FT synthesis with wood based synthesis gas Upgrading of the raw FT products Testing of FT products Folie 14

13 Different Flow Regimes Typical Flow-Regime Map for the Bubble Column Reactor (1) Folie 15

14 Upscaling of FT slurry reactor Efficiency of bubble column slurry reactor (BCSR) is strongly depended on the hydrodynamic regime of the bubble movement Homogenous Regime Transition Regime Heterogeneous Regime Churn up turbulence increase hold up of small bubbles 4 times more efficient than homogenous regime 16

15 Cold flow model Several tests with water and naphtha carried out with cold flow model laboratory plant Variation of gas superficial velocity and slurry concentration Investigation of effect on pressure drop and gas hold up» Switch from water to naphtha is changing hydrodynamics significantly, Weber number (We) can be employed for comparison We > 2 bubble breaking and axial mixing => heterogeneous regime! 17

16 Actual status Commissioning is ongoing First experiments are planned for October 2016 Folie 18
