A synthesis novel catalyst and development design of oscillation baffled reactor for oxidative desulfurization of light gas oil

Sulfur compounds present in diesel fuel pose significant environmental and health concerns. This study introduces a novel approach to remove sulfur from light gas oil through oxidative desulfurization (ODS) using a mesoporous Pd/Zeolite catalyst in an oscillatory baffled reactor (OBR). A series of experiments were conducted to investigate the influence of various parameters, including temperature (40-80 °C), residence time (4-12 minutes), and oscillation frequency (0.4-1.2 Hz), on the sulfur removal efficiency. The mesoporous structure of the catalyst facilitated the adsorption and oxidation of sulfur-containing compounds. The OBR design significantly enhanced mass and heat transfer, improving sulfur removal.Under optimal conditions (80 °C, 12 minutes residence time, and 1.2 Hz oscillation frequency), a remarkable sulfur removal efficiency of 93.11% was achieved. This research provides a promising pathway towards producing cleaner and more environmentally friendly diesel fuels.
