摘要: 将NiO/γ-Al2O3催化剂制成自支撑的薄片,采用原位红外的方法探究了噻吩分子在Ni上的吸附模式。将稀土Ce引入,对NiO/γ-Al2O3催化剂改性,发现Ce可以改善NiO的还原性能,并增强噻吩吸附时的S-金属直接作用,改善了噻吩脱硫的选择性。

Abstract: NiO/γ-Al2O3 catalyst was prepared into self-supporting wafers, and the adsorption patterns of thiophene molecules on Ni were investigated by FT-IR spectroscopy. Rare earth Ce was introduced to modify NiO/γ-Al2O3 catalyst, and it was found that Ce improves the reduction performance of NiO, and enhances the direct interaction of sulfur-metal on thiophene adsorption, thus improves the selectivity of thiophene desulfurization.

Key words: Ni, In-Situ FT-IR, thiophene, adsorption
