主　　题：CNTs cobalt niobium Fischer-Tropsch synthesis 

摘      要：Cobalt-based catalysts were prepared by a wet impregnation method on carbon nanotubes （CNTs） support and promoted with *** were characterized by nitrogen adsorption,TEM,XRD,TPR,TPO and *** of niobium increased the dispersion of cobalt but decreased the catalysts ***-Tropsch synthesis （FTS） was carried out in a fixed-bed microreactor at 543 K,1 atm and H2/CO=2 for 5 *** of niobium enhanced the C5＋ hydrocarbons selectivity by 39% and reduced methane selectivity by 59%.These effects were more pronounced for 0.04%Nb/Co/CNTs catalyst,compared with those observed for other niobium compositions.
