| Summary: | This study introduces a novel, non-extractive Oxidative Desulphurisation (ODS) method for kerosene using a three-phase
Oscillatory Baffled Reactor (OBR). The process utilises commercial bentonite clay (aluminium silicate hydrate) loaded
with 15 wt% vanadium pentoxide (V₂O₅) as a cost-effective catalyst. Catalyst characterisation showed surface areas of
56 m²/g for bentonite and 50.13 m²/g for the V₂O₅/bentonite composite. Structural and thermal properties were analysed
using X-ray diffraction (XRD). The ODS process was tested under various conditions, including temperatures (40–80°C),
residence times (15-120 min), oscillation intensities (63.79–382.8 Reo), and sulphur concentrations (84.4–578 ppm).
The optimal result, 81.73% sulphur removal, was achieved at 50°C, 578 ppm sulphur, and Reo = 382.8. Kinetic analysis
revealed a second-order reaction with a low activation energy of 46.39 kJ/mol for dibenzothiophene (DBT) oxidation.
Unlike previous studies that relied on synthetic or metal-heavy catalysts, this research highlights the effectiveness of a
natural, low-cost bentonite-based catalyst. It offers a sustainable pathway for cleaner fuel production and contributes
valuable insights into reaction mechanisms and kinetics, supporting future scale-up of eco-friendly desulphurisation
technologies. |
