采用水热法合成了氧化锌纳米微结构，通过改变锌盐种类考察其对氧化锌形貌的影响，并用等体积浸渍法在氧化锌上负载金属Ni，制备反应吸附脱硫剂，以正庚烷-噻吩为模拟汽油并在固定床反应器装置上评价反应吸附脱硫性能。通过X射线衍射（XRD）、N₂吸附-脱附（BET）、扫描电镜（SEM）等方法对该催化剂进行表征。研究表明，不同锌盐可导致不同的ZnO表面形貌，从而影响脱硫性能。在320℃、0.6 MPa、空速4 h^-1条件下，以醋酸锌为锌源所制备的脱硫剂的脱硫率最高可达97.5%，并具有良好的稳定性。

Zinc oxide nanoparticles are synthesized by hydrothermal method and the effect of zinc salt on the morphology of zinc oxide is investigated by adding different kinds of zinc salts in the synthesis.Through equal volume impregnation method,Ni is loaded on zinc oxide to prepare catalyst as a desulfurization agent in the way of reaction adsorption.The desulfurization performance of prepared catalyst is evaluated in a fixed bed reactor by using n-heptane-thiophene as simulated gasoline.This catalyst is characterized by X-ray diffraction (XRD),N₂ adsorption desorption (BET),scanning electron microscopy (SEM) and other measurements.It is found that different zinc salts can lead to different morphologies of ZnO surface,thereby affecting the desulfurization performance.At 320℃,0.6 MPa and 4 h^-1 of space velocity,the desulfurization efficiency over the catalyst made from zinc acetate is the highest,reaching 97.5%,with good stability.
