Abstract:Mesoporous g-C3N4 was prepared by SiO2 by a hard template method. Then the prepared mesoporous g-C3N4 was calcined at 500, 550 or 600℃ and its final products are assigned as CN-500, CN-550 and CN-600, respectively. The above calcined mesoporous absorbents were further characterized by XRD, TEM, FT-IR, FPD and N2 absorption-desorption, and their desulfurization performance for simulated fuel and jet fuel were investigated as well. Experimental results indicate that CN-550 has the best absorption capacity for thiophene, i. e., 24 mg(S)/g in simulated fuel. For jet fuels, the absorption capacity of CN-550 can be 10.46 mg(S)/g. After jet fuels were treated by NaOH, which eliminated the effect of antioxidant from fuel, the absorption capacity could increase 50%. The gas chromatogram analytical results for sulfur compounds suggest that the prepared absorbents have better absorption capacity for thiophene than benzothiophene due to size and steric effects. This is the main reason of their poor desulfurization performance for jet fuels. © 2019, Editorial Office of Acta Petrolei Sinica(Petroleum Processing Section). All right reserved.
