For many years ahead, it is predicted that energy for domestic needs is still dominated by fuel oil. In correlation with descendance of Indonesian crude oil deposites, the refining of heavy oil should be our concern. One of the heavy oil fraction that could transform into fuel oil is coker naphtha. Coker naphtha contains a large number of contaminants, such as sulphuric compounds, nitrogen compounds, and olefins (unsaturated hydrocarbon). The removal of these contaminants can be done with hydrotreating processes. One of catalyst type usually used in hydrotreating processes is NiMo/&#947;-Al2O3 catalyst. Until today, hydrotreating catalyst used in Indonesian petroleum industries is an import comodity. Actually, the raw material for this catalyst can be found in Indonesia. The making process of this catalyst is relatively easy. For these reasons, it will be a very good if we can make hydrotreating catalyst in Indonesia.<p> <br /> <br /> <br /> <br /> <br /> This research's target is to make NiMo/&#947;-Al2O3 for hydrotreating of coker naphtha, with high reproducibility. Catalyst (product) of this research is wanted to has the characteristics which is close to or even better than commercial NiMo/&#947;-Al2O3 catalyst.<p> <br /> <br /> <br /> <br /> <br /> The method of catalyst making used in this research is impregnation method. Raw material used is ammonium heptamolybdate (AHM) and molybdenum trioxide (MoO3) as the source of Mo (active phase), nickel nitrate solution as the source of Ni (promoter), phosphoric acid solution as the source of P (additive), and comercial gamma-alumina as catalyst's support. Spesific surface area of catalyst sample is to be tested with Brunauer-Emmett-Teller (BET) method, and the active phase's structure is to be tested with X-Ray Diffraction (XRD).<p> <br /> <br /> <br /> <br /> <br /> The result of this research showed that catalyst made from AHM will be reproducible at the ratio of H3PO4:MoO3 0.72, MoO3:NiO 2,61, and MoO3 concentration in the solution is 0,35 gr/mL. For the catalyst that made from MoO3, the reproducibility occurs at ratio of MoO3:NiO 2.61 dan MoO3:NH4OH 0.25.
