Adsorptive Desulfurization of Model Gasoline on Organic - Inorganic Modified Montmorillonite

Abstract:

The phenyl trimethyl ammonium bromide (PTMAB) and Keggin polyhydroxyl aluminum cations (Al13) as pillared agent and montmorillonite as the carrier, organic - inorganic pillared montmorillonite was prepared through sol-gel method to remove sulfur in model gasoline. The results showed when adsorption time was 1.5 h and reaction temperature was 40 °C, the maximum adsorption capacity of PTMAB-Al-MMT was 5.32 mg/g. The modified materials were characterized by X-ray diffraction, Nitrogen adsorption-desorption and NMR techniques to investigate the material structure and the adsorption mechanism. After the intercalation of PTMAB and Keggin Al13 in MMT, the interlayer d-spacing, specific surface and pore volume area increased to 1.10 nm, 41.23 m2 /g and 0.16cm3/g, respectively.
