| Popis: | In this study a non-hydrotreated kerosene was subject of experimental investigation via Hydrodynamic Cavitation Assisted Oxidative Desulfurization (HCAOD) process. Effects of various parameters affecting the desulfurization and cavitational yield of the process were studied. Hydrogen peroxide and Formic acid (HCOOH) were utilized as the oxidant and catalyst agents, respectively. Experiments were performed at constant temperature (50 °C) with various oxidant to sulfur molar ratio (nO/nS) (10–40), acid to sulfur molar ratio (nA/nS) (30–120), HC inlet pressure (3−6 bar) and oxidation time (10−30 min). A maximum sulfur removal of 95.8 % was achieved at 5 bar of HC inlet pressure using oxidant to sulfur molar ratio (nO/nS) of 30 and acid to sulfur molar ratio (nA/nS) equal to 90 within 30 min of the treatment. This value was markedly higher than what was obtained using similar conditions in the absence of HC. Furthermore, yield efficiency evaluation implied that cavitational yield of 2.47 × 10−3 mg J-1 using the optimum HCAOD conditions can be attained. However, the maximum yield of 4.23 × 10−3 mg J-1, was obtained having similar conditions with the treatment time of 10 min. The outcome highlights the impact of HCAOD as a promising process for intensification of oxidative desulfurization. |
