Two types of well-known characterization 40%Fe/60%Ni/Al2O3 catalysts were
prepared using incipient wetness (catalyst A) and co-precipitation (catalyst B)
procedure and activity and selectivity to light olefinic product in Fischer- Tropsch
Synthesis have been studied in a fixed-bed reactor under the different operating
conditions. The results showed that the incipient wetness catalyst had higher activity,
selectivity to light olefin and C5+ product and lower selectivity to methane and WGS
activity at stable period. Also, it was found that higher iron dispersion enhances the
negative effects of water such as low CO conversion, low olefin selectivity and
higher methane and CO2 selectivity.
