| 摘 要： | 采用重量法测定了温度为373 K、335 K和302 K时,噻吩、苯和正辛烷在NaY分子筛及CeY分子筛上的吸附等温线。结果表明，各温度下,噻吩在NaY分子筛和CeY分子筛上的饱和吸附量基本相同，并且其吸附量相对于苯和正辛烷较大。苯和正辛烷在CeY分子筛上的饱和吸附量很小，且较NaY分子筛上的吸附量明显的下降。CeY分子筛对噻吩有更高的选择性。

| Abstract: | Adsorption of thiophene,benzene and octane on NaY and CeY zeolites at different temperature was studied using Intelligent Gravimetric Analyzer(IGA). The results showed that saturation loadings of thiophene on NaY and CeY were similar at the same temperature;loadings of thiophene were higher than that of benzene and 1-octane;saturation loadings of benzene and 1-octane were remarkably lower on CeY zeolites than on NaY zeolites.The selectivity to adsorption of thiophene on CeY was superior to that on NaY. |

| Keywords: | Y zeolite selective adsorption desulfurization thiophene benzene n-octane |
