摘要： 采用等体积浸渍法制备了C u HY分子筛吸附剂, 运用 XR D表征了吸附剂的晶体结构, P y - F T - I R技 术表征了吸附剂的表面酸性能, 利用固定床穿透曲线技术、 WK - 2 D微库仑仪评价了改性分子筛的吸附脱硫性能。结 果表明, 当铜负载量为4%时, 其吸附脱硫能力较佳, 随着分子筛吸附剂的表面B酸量和表面L酸量比值的减小, 其 吸附脱硫性能越强。而当铜负载量较大时, 因其表面出现氧化铜, 而使其表面基本不存在B酸, 吸附脱硫能力大大 减弱。

Abstract: The CuHY zeolites adsorbents with different Cu loadings were prepared via impregnation method. The crystal structure of the adsorbent was characterized by XRD, and the surface acidity was measured by PyFTIR technique. The adsorption desulfurization performance was evaluated using fixed bed method with a WK2D micro coulometer analyzer. The results show that the adsorbents have the best adsorption desulfurization ability when the copper loading is 4%. The adsorption desulfurization performance becomes better with the decrease of the ratio of B acid amount and L acid amount. However, the adsorption desulfurization ability reduces severely, when copper loading is too large which results the surface copper oxide species, even though there is no B acidic sites existing on the surface of the adsorbent.
