Abstract
Mn/Al-SBA-15 absorbent was synthe sized by impregnation using Al-SBA-15 prepa red by grafti ng method as sup port, manganese acetate asp recursor of active com ponent.The samples were characteriz ed by means of XRD, N2 ad sorption-desorption, NH3-TPD, Py-FTIR and XPS.The adsorbent was used for adsorption desulfurization of simulated gasoline.The optimum molar ratio of Al /Si was determined through combining characterization of samples and their desulfurization performance.The mechanism of adsorption desulfurization was proposed .The regenera tion prop erties were alsos tudied.The results showed thatw hen the molar ratio of Al/Si was 1 ∶45, the perf ormance of adsorbent wa s the best.The thiophene was adsorbed through acid-base reaction.The intr oduction of Al improved the stability and the regeneration of the adsorbent.关键词
