摘　　要：采用离子交换法对HY分子筛进行改性制备了Fe(Ⅲ)Y分子筛,采用X-射线衍射及N2吸附-脱附技术进行表征,并测试了其吸附性能。结果表明,离子交换法制备的Fe(Ⅲ)Y分子筛比表面积等结构参数较HY分子筛的略有降低,较好的保持了分子筛的晶体结构。在吸附时间2h,吸附温度70℃,剂油比为0.04时,Fe(Ⅲ)Y分子筛的吸附脱硫率可达到68.9%。分子筛再生性能测试表明,Fe(Ⅲ)Y分子筛重复使用4次后脱硫率下降了9.1%,说明催化剂稳定性及再生性能良好。HY molecular sieve was modified to prepare Fe（ Ⅲ）Y molecular sieve by using ion exchange method and was characterized by means of XRD and N2 adsorption-desorption. The adsorptive desulfurization performance was also studied. The results showed that surface area structure parameters of Fe（ Ⅲ）Y molecular sieve was slight- ly lower then HY molecular sieve, and the crystal structure of HY molecular sieve was maintained better. Under the optimum conditions of an adsorption temperature of 70℃, a sorbent to oil ratio of 0.04 （by volume） , and an adsorption time of 2h, the sulfur removal rates reached 68.9%. Determination of regeneration performance of Fe （ Ⅲ） Y molecular sieve was repeated four times and the desulfurization rate decreased by 9.1%, indicating good catalyst stability and regeneration properties with Fe（ Ⅲ）Y molecular sieve.
