一种Mo-Ni催化剂在粗苯与洗油混合物加氢中的应用
摘要：
本发明公开了一种Mo-Ni催化剂在粗苯与洗油混合物加氢中的应用，所述Mo-Ni催化剂包括如下组分：4～10wt%的NiO，10～20wt%的MoO3，0.1～2wt%稀土元素中的一种或几种的混合物，其余为载体γ-Al2O3-ZrO2。其应用包括如下步骤：（1）将粗苯与洗油混合物和氢气混合，使形成的混合物在Mo-Ni催化剂作用下，于175～235℃、3.0～8.0MPa下反应；（2）将上述产物和氢气以1:800的体积比混合后在加氢催化剂作用下，于280～385℃、3.0～8.0MPa下反应即可。上述Mo-Ni催化剂可以去除粗苯与洗油混合物中大部分的杂质，最终得到高纯度的产品。
摘要（英）：

The invention discloses application of a Mo-Ni catalyst in hydrogenation of a mixture of crude benzene and absorber oil. The Mo-Ni catalyst comprises one substance or a mixture of multiple substances selected from the following components by weight percent: 4-10wt% of NiO, 10-20wt% of MoO3 and 0.1-2wt% of rare earth element, and the balance of a carrier gamma-Al2O3-ZrO2. The application comprises the following steps of: (1) mixing the mixture of crude benzene and absorber oil with hydrogen, so that the formed mixture reacts in the presence of the Mo-Ni catalyst at 3.0-8.0MPa and 175-235 DEG C; and (2) mixing the product with the hydrogen according to the volume ratio of 1:800 to react in the presence of a hydrogenation catalyst at 280-385 DEG C and 3.0-8.0MPa. The Mo-Ni catalyst can remove a large part of impurities in the mixture of crude benzene and absorber oil, and a high-purity product can be obtained finally.
