ABSTRACT
The objective of this work is to study the effect of calcination atmosphere with usage of the direct reduction on the cobalt over the structural catalyst such as granule type γ-Al2O3. This work also investigates the impact on the microstructure by introducing ruthenium with slurry impregnation method. To neglect the consideration of the term as the alloy and bimetallic catalyst, the relative higher weight ratio of Ru to total Co was fixed to
atomsphere and impregnation setp as Ru-Co (1st H2) and Ru-Co (1st Air).
