This project focuses on preparation of Fischer-Tropsch (FT) catalyst by using strong electrostatic adsorption (SEA) method. The simple catalyst synthesis method of strong electrostatic adsorption is applied to cobalt-iron (bimetallic) system on carbon nanotubes support. The pH value plays an important role in the deposition of metal precursor using SEA method. Iron was incorporated into cobalt at ratio of 10, 20 and 30 wt"lo.The physico-chemical properties, FT activity and selectivity of the bimetallic catalysts were analyzed and compared with those of monometallic cobalt catalysts at similar operating conditions (H2/CO = 2: l molar ratio, P = Atmospheric and T = 220 0 C). The average size of metal oxide particles deposited on the inner and outer walls of the CNTs was 6±1.5mn and 6.5± 3nm, respectively. Using the 90Co10Fe/CNT catalyst, the CO conversion was 2.5% and C/ selectivity was 0.85%. Other composition did not produce ct hydrocarbon.
