Abstract

Ru/Al₂O₃ catalyst was investigated by using Mn addition for Fischer-Tropsch synthesis under pressurized conditions. On the basis of catalyst activity, selectivity and deactivation, small amount of Mn addition such as Mn/Al=1/19 molar ratio on Ru/Mn/Al₂O₃ was effective for improving the catalytic performance, where Ru/Al₂O₃ was deactivated in the slurry phase reaction. Under high pressure of 6 MPa, equilibrium CO conversion was estimated to be about 96%.
