Abstract
The performance of the batch oxidative desulfurization (ODS) process for the removal of dibenzothiophen (DBT) chemical from fuel (light gas oil) is being investigated using newly developed nano-supports (nano-catalyst). Mercury oxide (HgO) nanoparticles based on tin oxide (SnO), barium peroxide (BaO2), and arsenic trioxide (As2O3) nanoparticles were used to make the nano-catalysts, which have outstanding catalytic properties. Several reaction temperatures (65-85) oC, concentrations of oxidant (hydrogen peroxide (H2O2)) from (2-6) ml, and agitation speeds (450-850) rpm were used at a constant reaction time (30 min) and various catalysts to acquire a better knowledge of the process. With a reaction temperature of 75 oC, a volume of oxidant of 6 ml, and an agitation speed of 850 rpm, greater than 83.06 percent of the process conversion from DBT was obtained at the catalyst (HgO/SnO). The findings demonstrate that increasing the reaction temperature, H2O2 concentration, and agitation speed increases the effectiveness of sulfur compound removal.
