摘要： A series of Ni/AlMCM-41 catalysts with different nickel contents was prepared via the incipient wetness impregnation method. The effects of the nickel content on the structure, acidity and metal function of the catalysts were studied by using different techniques. In the test of n-dodecane hydroconversion, it was found that the metal and acid functions were well balanced over a 2.0%Ni(mass fraction)/AlMCM-41 catalyst, which gave the maximal isomerization selectivity and a homolytic cleavage products.
