摘要
Adsorptive desulfurization performed by adsorbing dibenzothiophene from model fuels and gasoline over metal-organic framework MIL-47. The MIL-47 was synthesized by the microwave method and characterization supplied by different techniques such as scanning electron microscope, Brunauer-Emmett-Teller analysis, Fourier transform infrared, and X-ray powder diffraction analysis. For optimizing the adsorption process, central composite design was carried out in this study, and a gas chromatograph measured the concentration of dibenzothiophene. The maximum adsorption capacities (Q(0)) MIL-47 for dibenzothiophene are 1000 mg g(-1). The increment ofQ(0)is may be due to the synergistic influence of pi-complexation (betweenVand dibenzothiophene). Furthermore, reusability of MIL-47 was confirmed by regenerating it via ethanol (5 cycles) and RSD 4.53%. [GRAPHICS] .
