先采用水热法制备出氧化锌(ZnO)纳米线,然后以硝酸镍作为活性组分的前驱体盐,ZnO纳米线作为载体,采用等体积浸渍法制备出镍(Ni)/ZnO催化剂,考察了水热反应时间对ZnO纳米线微观形貌及Ni/ZnO催化剂孔结构的影响,并在80 mL固定床反应管中考察了Ni/ZnO催化剂的反应吸附脱硫性能.结果表明:当水热反应时间为36 h时,所制备ZnO纳米线特征衍射峰尖锐,呈现花簇状生长;Ni/ZnO催化剂的比表面积最大,其值为35.25 m2/g;吸附脱硫反应持续60 h后,脱硫率仍高于91％.%ZnO nanowire was prepared by hydrothermal method,then with nickel nitrate as the precursor salt active component,ZnO nanowire as carrier,Ni/ZnO catalyst was prepared by equal volume impregnation method,the influences of hydrothermal reaction time on ZnO nanowire morphology and pore structure of catalyst Ni/ZnO were studied,and the reactive adsorption desulfurization performance of Ni/ZnO catalyst was investigated in an 80 mL fixed bed reaction tube.The results showed that when the hydrothermal reaction time was 36 h,the characteristics diffraction peak of the prepared ZnO nanowire was sharp,showing the growth as flower like.Ni/ ZnO catalyst has the largest specific surface area,and its value was 35.25 m2/g.The adsorption desulfurization reaction lasted for 60 h,and the desulfurization rate was still higher than 91％.
