摘　　要：采用等离子发射光谱(ICP-AES)、比色分析(UV-vis)、碳元素分析仪、X光衍射(XRD)和低温氮物理吸附仪对未知催化剂的物化性质进行了剖析。结果表明:该未知催化剂主要成分是氧化镍、氧化铝和碳,两种氧化物质量分数之和超过了90%,碳的质量分数约为4%。催化剂的比表面积为189㎡/g、孔容为0.32 cm3/g、平均孔径为6.85 nm。X光衍射物相分析表明该催化剂以无定形三氧化二铝为载体,担载氧化镍和碳,其中氧化镍和碳以聚集态存在。A kind o f hydrocatalyst was analyzed by Inductively coupled plasma atomic emission spectrometry （ICP-AES）, ultraviolet-visible spectroscopy （UV-vis）, carbon element analyzer, X-ray diffraction and N2 adsorption-desorption. Results show that the catalyst mainly consists of nickel oxide, aluminium oxide and carbon,the amount of nickel oxide and aluminium oxide is more than 90%, that of carbon is only 4%,the catalyst surface area is189 m^2/g, pore volume is 0.32 cm^3/g, pore size is 6.85 nm, the catalyst carrier is amorphous aluminium oxide, aetitire metal is nickel oxide.
