oa Characterization of Produced Eruca Sativa (Taramira) Hydrogenated Renewable Diesel

This work offers a methodical examination of the hydrogenation of Taramira oil using γ-Al2O3 assisted nickel molybdenum catalyst at pressure and temperature of 400⁰C and 4MPa respectively. It was observed that the conversion of fatty acids and triglycerides into hydrocarbons is significantly influenced by temperature and pressure. The resulting mixture of gases and other substances is subjected to fractional distillation, wherein it is separated at various boiling points. The chemical composition of the obtained taramira Hydrogenated Renewable Diesel (HRD) was carried out using Gas Chromatography Flame Ionization Detector (GC-FID) chemical composition testing. The paraffin chain C15–C18 i.e., diesel fuel ranges accounted for the final product's major composition; miscellaneous components include paraffin, lubricating oils, etc. A hydrogenated renewable paraffinic fuel's physicochemical characteristics were evaluated and contrasted with those of Biodiesel and conventional diesel. When comparing Hydrogenated renewable diesel (also known as green diesel), biodiesel, and diesel, it is determined that green diesel has the finest physical-chemical qualities. With its high cetane index and favorable cold flow characteristics, HRD is used as a "drop-in" fuel. Conversely, oxidation stability and kinematic viscosity for both diesel and HRD were almost identical. The obtained HRD shows a calorific value higher than the biodiesel. The elemental analysis for the obtained hydrogenated renewable diesel uses a CHNS elemental analyzer. The analysis results show that the carbon-hydrogen content of HRD is comparable to that of diesel and higher than that of biodiesel.
