Design and optimisation of a multi-stage bubble column slurry reactor for Fischer-Tropsch synthesis

Abstract For carrying out the Fischer–Tropsch synthesis of heavy paraffins starting from syngas (CO+H 2 ), a multi-stage bubble column slurry reactor design is carried out. The advantages of this reactor configuration with respect to a conventional slurry reactor design, consisting of one well-mixed stage, are (a) increased syngas conversion, and (b) increased reactor productivity. The multi-stage bubble column construction requires installation of additional cooling surface area in order to keep the exothermic reaction within the desired temperature limits.
