The kinetic study of catalytic estrification by nickel based catalyst promoted with different metal oxides as a catalyst

摘要: Aluminum oxide is the most famous promoters for nickel (1) several publication were given in the literature which recommended the use of Ni/Al2O3 as catalyst. Some of them recorded partial reduction of nickel in presence of aluminum oxide promoters. Systematic studies on Ni/Al2O3 catalyst Armstrong and Hilditch (2). These are a lot of works (3) used Cr2O3 as promotes for nickel in hydrogenation dehydrogenation processers which founded as good promoters due to its high melting point, an indication for the efficiency of this catalyst for the hydrogenation dehydrogenation estrifications processes was. given by Sadek, Taylor (4), wassel and Amira Different metal oxide promoters such as
