Acidity regulation of Fe-based catalysts and its effect on the selectivity of HDS reaction pathways

Funds: The project was supported by the Foundation for Innovative Research Groups of the National Natural Science Foundation of China (22021004) and National Natural Science Foundation of China (21776304).
  • 摘要: 以Fe作为主活性金属、Zn作为助活性金属,制备了Y型分子筛改性的Fe基加氢脱硫(HDS)催化剂。采用低温氮气物理吸附、X射线衍射(XRD)、氢气程序升温还原(H2-TPR)、氨气程序升温脱附(NH3-TPD)、扫描电子显微镜(SEM)、X射线光电子能谱(XPS)和吡啶红外(Py-IR)等表征方法对改性前后Fe基催化剂的形貌、孔结构、分散性、还原性、电子缺陷结构以及酸性等变化进行了研究,并使用固定床反应器对Fe基催化剂的HDS性能进行了评价。结果表明,Y型分子筛的引入提供了Brønsted(B)酸中心,使得Fe基催化剂的脱硫率提高了10.7%−34.1%。同时,B酸中心提高了催化剂的直接脱硫(DDS)反应路径的选择性。此外,B酸中心在促进DDS反应路径选择性增加的同时,抑制了预加氢脱硫(HYD)反应路径中四氢二苯并噻吩(THDBT)和六氢二苯并噻吩(HHDBT)更进一步的深度加氢,从而在保证脱硫率提升的同时又降低了氢耗。其根本原因可能是Y型分子筛的引入增强了催化剂的酸性,特别是B酸中心和活性金属之间的相互作用促进了电子转移,从而调节了Fe物种的电子缺陷结构,进而提升了催化剂的HDS性能。
