Abstract
Co/ɣ-Al2O3 catalyst was prepared by incipient
wetness impregnation of the ɣ-Al2O3 support using an
aqueous solution of cobalt nitrate. The catalyst was
characterized by XRD, BET and TPR. It was evaluated in a
fixed-bed reactor to determine the effect of space velocity on
the CO conversion, CO conversion rate, CH4 selectivity and
C5+ selectivity during Fischer-Tropsch reaction. CO
conversion decreased while the CO conversion rate linearly
increased with increasing the space velocity. The CH4
selectivity was not significantly affected by the space
velocity as it fluctuated between 5 and 6%.
