Abstract
The aim of this study was to investigate the effect of
the operating temperature on the performance of a Fe/Al2O3 catalyst
with low Fe loading during Fischer-Tropsch reaction. The catalyst
was prepared by incipient wetness impregnation method and
evaluated at 250 – 300 oC. The experimental results show that both
selectivity and catalyst activity are strongly affected by the operating
temperature. Increasing the temperature leads to increased catalytic
activity and shifts the selectivity of products towards lighter
hydrocarbons. While a clear dependence of the olefin-to-paraffin
ratio (O/P) for C4 and C5 hydrocarbons on the operating temperature
was not obtained, the O/P for C2 and C3 hydrocarbons was found to
decrease with an increasing temperature.
