The catalysts were prepared using a wet impregnation method and promoted with potassium. Samples were characterized by nitrogen adsorption, H2-TPR, and TEM. The Fischer-Tropsch Synthesis (FTS) was carried out in a fixed-bed microreactor 220{\^A}oC, 1 atm, H2/CO=2 and a velocity (SV) =12 L/g.h. for 5 h. Addition of potassium into Co/CNTs decreased the average size of cobalt nanoparticles and the catalyst reducibility. Potassium-promoted Co catalyst resulted in appreciable increase in the selectivity of C5+ hydrocarbons and suppressed methane formation. The 0.06KCo/CNTs catalyst enhanced the C5+ hydrocarbons selectivity by a factor of 23.5 and reduced the methane selectivity by a factor of 39.6 {\^A}{\copyright} 2012 American Institute of Physics.}, issn = {0094243X}, author = {Ali, S. and Mohd Zabidi, N.
