Experimental Investigation and Optimization for Desulfurization of Diesel Fuel Using Microwave Irradiation and Activated Carbon

Abstract

Due to increased emissions of sulfur compounds, the extensive use of diesel fuel in industry, transportation, and power generation causes a number of environmental issues. Because sulfur-containing chemicals have a tendency to cause a number of environmental problems, diesel fuel must be free of them. One of the best techniques for this is the use of microwave irradiation technology to remove oxidative sulfur in diesel fuel. quick and affordable processes use microwave heating in conjunction with peroxide oxidation, 7.5 ml of acetic acid, and 1 g of activated carbon to treat sulfur-containing diesel fuel. The purpose of the study was to assess efficiency hydrogen peroxide as oxidizing agent and the acid as activator. This technique uses microwave radiation to create electromagnetic waves. Software was used to optimize operations for optimal conditions, and the experiments made use of a rotatable central composite design with three variables. The findings showed that 500 watts produced the best sulfur extraction efficiency from diesel fuel, with a peroxide-to-diesel volume ratio of 0.7 and an optimal treatment duration of 150 to 160 seconds. With a maximum sulfur removal efficiency of 85%, the diesel fuel's initial sulfur concentration is 2865 ppm. The ability of microwave technology to extract sulfur from diesel fuel is proof that it is a practical and environmentally beneficial technique.
