Abstract

Petroleum fuel is still the main energy source today but causes environmental problems such as SOx gas emissions. The Oxidative Desulfurization (ODS) method removes sulfur from fuel under mild conditions. ZSM-5 is a catalyst framework considered promising in the ODS process but the small pores cause a steric barrier. The hydrophobic, mesoporous Fe-Co/ZSM-5Hierarchy catalyst was designed using the dealumination method with steam treatment to overcome the steric barrier and biphasic hindrances which are problems in this ODS process. The Fe-Co/ZSM-5Hierarchy catalyst is effective for the ODS process at a temperature of 45 °C, 45 min, the amount of catalyst used is 0.2 g, oxidant at an O/S ratio of 2, and without mass transfer agents. The embedded Fe-Co ratio shows effective mass activity by providing a TOF number of 205 h-1 on the Fe-Co(5)/ZSM-5 Hierarchy and 157 h-1 on the Fe-Co(15)/ZSM-5 Hierarchy catalyst.

Abstract

Non-edible oil, such as Jatropha oil, is an interesting feedstock for the development of renewable diesel (green diesel). Catalytic deoxygenation using natural zeolite-supported Mo-based catalysts is a promising process for the conversion of Jatropha oil to green diesel. Mo and MoP catalysts supported on natural zeolite were synthesized by wet impregnation at a concentration of 5% (w/w). The catalysts were characterized by XRD, XRF, SAA and NH3-TPD. The catalysts were successfully synthesized with the appearance of Mo and MoP peaks on the catalyst diffractogram. XRF results also showed that Mo and P were present in the catalyst. Metal impregnation decreased the surface area and pore volume of the catalyst, but increased the average pore diameter. The NH3-TPD profile of the catalyst showed that the weak acid sites of both catalysts were larger than the strong acid sites. Based on the activity test of catalytic deoxygenation of Jatropha oil, the MoP/HZ catalyst produced a higher conversion (67%) and liquid product yield (79%) than Mo/HZ. This is associated with a larger pore diameter, so that the distribution of reactants on the catalyst surface is more optimal. However, the highest green diesel selectivity of 82% is produced by the Mo/HZ catalyst. The Mo/HZ catalyst is more oriented towards the HDO reaction, whereas the MoP/HZ catalyst is more oriented towards the DCO/DCO2 reaction.
