摘要
NH4+ doped PMoV composites catalytic materials are successfully prepared. The NH4+ doped H4PMo11VO40 composites have been tested as highly efficient catalysts in the ultra-deep desulfurization of fuel oils. The reaction conditions are optimized by testing the load of NH4+, temperature, O-2 flow velocity, and DBT concentrations. The optimal reaction conditions are given as follows: 0.1 g (NH4)(3)HPMo11VO40 as catalyst, reaction time 2 h, O-2 flow velocity 100 mL min(-1), and reaction temperature 120 degrees C, with a conversion of DBT reaching up to 100% in 90 min, and this catalyst could be used more than five times without significant loss of activity.
