摘要 以嫁接法制备的Al-SBA-15为载体,醋酸锰为活性组分前驱体,通过浸渍法制备Mn/Al-SBA-15吸附剂。利用X射线衍射(XRD)、N2吸附-脱附、NH3程序升温脱附(NH3-TPD)、吡啶-原位傅里叶变换红外(Py-FTIR)和X射线光电子能谱(XPS)等表征手段对吸附剂进行分析,以模拟汽油中噻吩的脱除反应为模型反应考察了吸附剂的吸附性能,确定了吸附剂的最佳Al/Si物质的量比,并结合表征结果对吸附剂脱硫过程进行机理探讨,最后研究了吸附剂的再生性能。实验结果表明,当Al/Si(mol ratio)为1∶45时,吸附剂脱硫性能最高;吸附剂主要通过酸碱作用吸附噻吩分子;Al的引入提高了吸附剂的结构稳定性,从而提高了吸附剂的再生性能。 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.
