| 摘 要： | 用静态吸附方法研究了CuY分子筛、CeY分子筛和CeCuY分子筛对3种含噻吩的模拟油的吸附。实验结果表明,在相同条件下,以上3种分子筛对模拟油A、B的脱硫率为95%左右,对含环己烯的模拟油C的脱硫率均低于63%。运用BET对分子筛孔结构进行表征和运用IR对吸附模拟油后的分子筛情况进行考察,分析结果表明,Cu和Ce离子交换后的分子筛,BET比表面积下降,微孔比表面积下降,由此影响对模拟油A、B中噻吩的吸附。IR谱图表明,以上3种分子筛都会吸附环己烯,是导致其对模拟油C脱硫率下降的主要原因。

| Abstract: | Adsorption behaviors on the various ion-exchanged NaY zeolites(with single Cu2+,Ce3+ and the combined Cu2+-Ce3+) in the three model fuels containing thiophene were investigated under static state conditions.The results showed that the CuY/CeY/CeCuY zeolites had a interesting desulfurization performace(about 95%) in model fuels A and B,While the desulfurization efficiency in model fuel C was sharply below to 63%.The pore structure of these zeolites was characterized by BET and the adsorption evaluation in mo... |
