Sammendrag
A biomass-to-liquid plant consists of pretreatment, gasification , syngas cleaning and
conditioning, Fischer-Tropsch (FT) synthesis, and products upgrading.
In the FT reactor the syngas is converted to liquid fuels on a cobolt (or iron) catalyst. There exist
different reactor types of FT units, such as slurry bubble column, fixed bed and microchannel
reactors. Here, we want to make a model of a fixed bed reactor of the FT synthesis in a new
simulation system called VMGSim. A gasification model is already in the system.
A kinetic model of the FT kinetics should be implemented in the simulation tool. This
kinetic model takes into account a limited number of components, both alkanes and
alkenes, and the selectivity to different products depends on composition and temperature.
New process configuration of the BtL plant will be evaluated.
