以仲丁醇铝为铝源,月桂酸为模板剂,采用一锅法制备了模板剂含量分别为0.66g,1.33g,2.66g(以下分别用MS1, MS2,MS3表示模板剂用量)的多级孔Al2O3载体.分别以磷酸二氢胺和硝酸镍为磷源和镍源,通过等体积浸渍法制备了Ni2P/多级孔Al2O3催化剂.用X射线衍射和N2吸附脱附技术进行表征,结果表明,所制氧化铝以γ-Al2O3相存在,磷镍组分以Ni2P相存在,具有微介孔多级孔道结构,微孔分布在0.8~2.0nm范围,介孔分布在4.965~10.32nm范围.以萘为模型化合物在小型连续固定床反应器上评价催化剂的加氢脱芳性能,结果表明,载体由于多级孔道结构,有效降低了传质阻力,有利于萘的加氢反应.当以模板剂用量为MS2(1.33g)的Al2O3为载体时,脱芳率和选择性最高,可达到97.74%和51%.“,”The Al2O3composite carrier with hierarchical pore with the template content of 0.66g,1.33g and 2.66g(MS1,MS2,MS3 was respec-tively used to represent the template content)was prepared by one-pot method with lauric acid as the template and aluminum sec-butoxide as the source of aluminum.Then the ammonium dihydrogen phosphate and nickel nitrate were used respectively as the source of phosphorus and nickel, and the Ni2P/Al2O3catalyst with hierarchical pores was prepared by equivalent-volume impregnation. The composites were characterized by X-ray diffrac-tion and N2adsorption-desorption. The results showed that the alumina of composite with hierarchical structure of micropore and mesopore existed in the phase of γ-Al2O3,and the active component composed of phosphorus and nickel existed in the phase of Ni2P,its micropore size distribution varied from 0.8nm to 2.0nm and its mesopore size distribution varied from 4.965nm to 10.32nm. The hydrogenation-dearomatization property of the catalyst was evaluated on mini continuous-flow fixed-bed reactor with naphthalene as the model molecules. The result showed that the mass transfer resis-tance of carrier was effectively reduced which was beneficial for the hydrogenation of naphthalene because of its hierarchical pore structure. The dearomatization efficiency and selectivity was the highest which was 97.74% and 51% respectively when the Al2O3carrier with hierarchical pores with a template content of 1.33g was used.
