Production of Green Fuel: A Digital Baffle Batch Reactor for Enhanced Oxidative Desulfurization of Light Gas Oil Using Nano-Catalyst

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 (۱۰۰, ۱۲۰ and ۱۴۰ °C), contact time (۱۵, ۳۰, and ۴۵ min) and oxidant (H۲O۲) amount (۲, ۳ and ۵ 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 ۸۳.۱ % using the modified nano-catalysts and new reactor (DBBR) at reaction temperature ۱۴۰ oC, batch time ۴۵ min, and H۲O۲ amount of ۵ 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.
