Abstract: The Co/SBA-15 catalyst prepared by incipient wetness impregnation with ethanol solution of cobalt nitrate exhibits higher dispersion of active metal cobalt, higher initial activity, and higher selectivity for C5+ hydrocarbons in Fischer-Tropsch synthesis than the catalyst prepared with aqueous solution.

Key words: ethanol impregnation, cobalt-based catalyst, SBA-15 molecular sieve, Fischer-Tropsch synthesis, pore structure
