该发明涉及一种用于芳烃饱和加氢的金属氮化物催化剂,是在γ-Al2O3载体上负载镍钼双金属氮化物。该催化剂中各活性组分的组成(质量分数)为Ni2.5%～10%,Mo6%～25%,Ni和Mo以Ni2Mo3N,Ni,Mo2N和少量氧化物共存的形式存在。催化剂的制备方法为:在500～550℃下焙烧γ-Al2O3载体4～5h;

This invention relates to a metal nitride catalyst for the saturation hydrogenation of aromatic hydrocarbons by supporting nickel-molybdenum bimetallic nitrides on a γ-Al2O3 support. The composition (mass fraction) of each active component in the catalyst is 2.5% -10% of Ni, 6% -25% of Mo and Ni and Mo are present in the form of Ni2Mo3N, Ni, Mo2N and a small amount of oxides. The catalyst is prepared by calcining the γ-Al2O3 carrier at 500~550 ° C. for 4~5 h;
