Abstract
The effect of space velocity on FT reaction has
been evaluated over a 10%Co/TiO2 catalyst prepared by
incipient wetness impregnation method. The catalyst was
tested in a fixed-bed reactor at 220oC, 20 bar and various feed
gas space velocities (20, 40 and 60 Nml/gCat/min). The CO
consumption rate, olefin to paraffin ratio, C5+ selectivity and
the chain growth probability (alpha) were found to increase
with an increase in feed gas flow rate. The results were
explained in terms of reactants partial pressures and mass
transfer in the reactor as function of CO conversion levels.
