제목 Deactivation of cobalt supported on pretreated alumina in Fischer-Tropsch synthesis under severe conditions  
초록 The catalytic deactivation of Co/pretreated-Al2O3 catalysts during Fischer–Tropsch synthesis has been investigated under severe conditions: (1) water added condition in a slurry reactor and (2) high temperature condition in a fixed reactor. The FT catalysts were prepared by using impregnation method with cobalt nitrate precursor on pretreated Al2O3 support (Co/Al, Co/P-Al, Co/Zr-Al, and Co/Zn-Al) .The Co/P-Al catalyst showed relatively low deactivation rate under two severe conditions as compared to the other catalysts. In the water added reactions, it was found that the adsorbed water led to the phase change of alumina surface to boehmite which would enhance oxidizing and restructuring cobalt particles on the support.
