随着炼油及化工生产的发展,金属型催化剂一直是研究的课题,相对比贵金属催化剂,金属Ni以其高的加氢活性,实用的经济性,无疑成为一直研究的热点。制备金属镍基催化剂通常采用还原的方式,由于金属镍的金属活动性以及还原剂数量的有限性,限制了其制备途径,本文讨论了利用不同还原剂制备镍基催化剂的方法,并阐述了相应的还原机理,对金属镍基催化剂以及金属镍基材料的制备具有一定的指导意义。
With the development of oil refining and chemical production, metal-based catalysts have always been the subject of research. Compared with noble metal catalysts, metal Ni has always been a hot spot for its high hydrogenation activity and practical economy. Preparation of metal nickel-based catalysts are usually used in the reduction of the way, due to the metal activity of nickel metal and the limited number of reducing the number of its limited preparation methods, this paper discusses the use of different reducing agents for preparing nickel-based catalysts, and describes the corresponding The reduction mechanism is of guiding significance to the preparation of metallic nickel-based catalysts and metallic nickel-based materials.
