The fischer—tropsch synthesis over a ruthenium catalyst under composition cycling

The influence of feed composition cycling on the activity and selectivity of the Fischer-Tropsch synthesis over an alumina-supported ruthenium catalyst was investigated using a fixed-bed reactor at 211°C and 446 kPa total pressure. Forced composition cycling suppressed the overall synthesis rate but increased the rates of formation of the C1 to C4 paraffins and shifted the paraffin/olefin ratio. On a etudie l'influence du cyclage de la composition d'alimentation sur l'activite et la selectivite de la synthese de Fischer-Tropsch sur un catalyseur au ruthenium depose sur de l'alumine, a l'aide d'un reacteur a lit fixe a 211°C et sous une pression totale de 446 kPa. Le cyclage force de la composition diminue la vitesse totale de synthese mais augmente la vitesse de formation des paraffines de C1 a C4 et modifie le rapport paraffine-olefine.
