NOVELTY - Diesel desulfurization comprises mixing activated carbon, attapulgite, and graphene at a mass ratio of 1:3:2 to prepare mixed granules; dipping the mixed granules in deionized water for 2-3 hours, and drying; adding the dried mixed granules to copper nitrate solution, heating to 150-200 degrees C, reacting for 2-5 hours, filtering, drying, and calcining; adding zinc oxide and calcium oxide to the mixture, ultrasonically dispersing for 20-30 minutes, drying, and sintering at 330-380 degrees C to obtain a mixed adsorption desulfurizing agent; adding the mixed adsorption desulfurizing agent to diesel oil for desulfurization; and removing wastewater. USE - Method for diesel desulfurization. ADVANTAGE - The method has simple operation, achieves removal of sulfur from diesel fuel with minimal octane effect.
