Abstract: Disclosed is a Co/Al2O3/SiC catalyst for Fischer-Tropsch synthesis exhibiting superior heat transfer and mass transport effects, wherein an Al2O3/SiC support in which alumina is coated on silicon carbide (SiC) with superior thermal conductivity is used and cobalt (Co) is supported thereon as an active component to provide a bimodal pore size distribution, and a method for preparing same. Use of the Al2O3/SiC support improves cobalt dispersion and enhances cobalt-support interaction, thereby inhibiting generation of cokes (carbon filaments). As a result, catalyst stability is improved and conversion of syngas (carbon monoxide and hydrogen) can be improved.
