A digital baffle batch reactor (DBBR) for oxidative desulfurization (ODS) reactions is designed and applied here to reduce the sulfur concentration presented in light gas oil (LGO) based on a novel homemade nano-catalyst (Copper Oxide (CuO)/Activated Carbon (AC)). With efficient impregnation, good pore size distribution, high activity, and higher surface area, the designed nanocatalyst (CuO/AC) demonstrated excellent catalytic efficiency. To evaluate the effectiveness of nanocatalyst (prepared experimentally), several experiments related to ODS reactions using the digital baffle batch reactor are carried out under moderate process conditions (reaction temperature (100, 120 and 140 °C), contact time (15, 30, and 45 min) and oxidant (H2O2) amount (2, 3 and 5 mL)). The experimental outcomes indicated that increasing the reaction temperature, batch time, and oxidant amount led to the reduced sulfur concentration of oil feedstock leading to a greener fuel. The efficiency of sulfur conversion is reported to be 83.1 % using the modified nano-catalysts and new reactor (DBBR) at reaction temperature 140 oC, batch time 45 min, and H2O2 amount of 5 mL. So, such new results using DBBR for ODS reactions based on CuO/AC as a new modified nanocatalyst have not been reported in the public domain and it is considered new results.
