Indonesian ESDM Ministry’s policy No.25 Year 2013 says that the use of aviation biofuel in air plane will be started at January 2016. At that year, the amount of bio-jet fuel (paraffinic kerosene) mixed in conventional jet fuel should be 2%. Paraffinic kerosene chemical composition is hydrocarbon with atom number C9 – C17. This composition can be made by palm kernel stearin which have lauric acid (C12:0) up to 50% and myristic acid (C14:0) about 20%. Unfortunately, bio oil (including stearin) has high oxygen compounds. Elimination of oxygen compounds is possible by hydrodeoxygenation (HDO) reaction which needs high pressure hydrogen and hydrotreating catalyst such as sulfided NiMo or CoMo. HDO reaction can produce different products. It can be paraffin with H2O or paraffin with CO or CO2 (decarboxylation). In this research, NiMoP/?-Al2O3 catalysts are made to produce n-paraffin and H2O (HDO selectivity). The catalysts are made with Ni/Mo atomic ratio between 0.01 – 0.03. Activity and selectivity testing from these catalysts are then compared with NiMoP catalysts which have Ni/Mo 0.29. HDO reaction is operated in batch reactor at 60 bar and 360 oC. NiMoP catalysts produced from synthesis have atomic Ni/Mo ratios 0.023, 0.016, and 0.012. The HDO selectivities are 58.40%, 60.04%, and 65.63%. While HDO selectivity for NiMoP catalysts with 0.29 Ni/Mo atomic ratio are only around 20%. Unfortunately, the activity and paraffinic kerosene yield for NiMoP synthesis are still inconsistent.
