| Popis: | Biodiesel is an alternative fuel that can be renewed and is more environmentally friendly. In this study, biodiesel was produced from used cooking oil (UCO) through saponification and transesterification reaction. Furthermore, hydrodeoxygenation was carried out over NiMo/ɣ-Al2O3 catalyst in batch autoclave reactor to produce green diesel. The reaction conditions were conducted at 30 and 50 bar and temperatures of 300, 350, 400 and 450°C. Characterization of gas products were conducting using GC-TCD, while the liquid products using GC-MS. Biodiesel and green diesel are calculated using %yield. The result of characterization of gas products using GC-TCD shows the components of H, O2, CO, CH4 and CO2 which indicate the selectivity of the hydrotreating HDO reaction to DCO/DCO2 and fracturing. While green diesel biodiesel liquid products contain methyl ester and ethyl ester compounds with saturated and unsaturated hydrocarbon chains with a range of C11−C25 and alkene hydrocarbon compounds. The quality of biodiesel and green diesel showed in accordance with Indonesian National Standard for Biodiesel. The effect of reaction condition to produce green diesel were studied to elucidate the hydrodeoxygenation process. |
