Abstract: The adsorptiondesorption isotherms of thiophene and benzene in the NiY and NiY/Beta zeolites, prepared by liquid phase ion exchange, have been investigated by an intelligent gravimetric analyzer (IGA) and the diffusion coefficients were also calculated. Properties of selective adsorptive desulfurization of FCC gasoline on the zeolites were evaluated by a fixedbed adsorption experiment. The results show that the NiY/Beta zeolites remain the microporous structure. The saturated adsorption amount of thiophene is larger than that of benzene and so it is to the diffusion coefficients. The better diffusivity of thiophene inhibits the adsorption of benzene, resulting in the absorption desulfurization capability of the NiY/Beta zeolites improved.

摘要： 采用液相离子交换法制备了NiY及NiY/Beta分子筛,利用智能重量分析仪测定了噻吩、苯在NiY、 NiY/Beta分子筛上的吸附灢脱附等温线,计算比较了噻吩、苯在分子筛上的扩散系数,同时使用固定床技术考查了改性后的分子筛对催化裂化汽油的吸附脱硫性能。结果表明,复合分子筛NiY/Beta然保持着较好的微孔结构,对噻吩的饱和吸附量大于苯的。而且噻吩在NiY/Beta分子筛上的相对扩散系数明显增大,而苯的扩散系数有所减少,这有利于噻吩在分子筛上的扩散过程,抑制了苯在分子筛上的吸附,从而提高了NiY/Beta复合分子筛对噻吩的选择性脱除能力。对于FCC汽油NiY/Beta复合分子筛也表现出更好的深度脱硫能力。
