In order to determine the stability of the catalyst，the recovery and recycling use of the ionic liquid phase containing thecatalyst were investigated.The WO3/g-C3N4（20%）could be reused in the oxidative desulfurization system containing H2O2 and[bmim]BF4.After each oxidative desulfurization cycle，the experiments for recovery of the ionic liquidcontaining catalyst were carried out using CCl4 as the extraction agent by means of rotary evaporation.After the fresh H2O2 and model oil were added into the recovered ionic liquid phase，the recycling experiments were implemented under the optimal conditions.As shown in Table 3，the desulfurization rate decreased from 98.46%to 96.81%after recycling five times.It may be concluded that the stability of H2WO4/g C3N4（20%）is higher thanks to the heterogeneous catalysis system.
