摘　　要：采用固相反应法制备了Ni-Zr非负载型催化剂,通过BET、XRD、H2-TPR和H2-TPD等手段对催化剂进行了表征,并评价了该系列催化剂的乙苯加氢活性。结果表明,相对纯Ni催化剂,Ni-Zr非负载型催化剂具有较大的比表面积,提高了活性组分的利用率。同时由于Ni、Zr两组分的相互作用,使Ni组分以游离NiO和难还原NiO两种相态存在;当二者比例适当时,Ni-Zr催化剂具有较强的吸附H2能力和较高的加氢活性。A series of unsupported Ni-Zr catalysts were prepared by solid-phase-reaction method, and characterized by using BET, XRD, H2-TPR and H2-TPD. Compared with pure Ni catalyst, the as prepared Ni-Zr catalysts possessed relatively large surface area, being beneficial to the utility of active component. It is suggested that the introduction of Zr into Ni catalyst led to not only the occurrence of interaction between Ni and Zr, but also the considerable increase of the adsorption capacity for H2. The Ni-Zr catalyst with suitable interaction of Ni and Zr showed excellent ethylbenzene hydrogenation activity.
