Novel composites made from monodispersed porous Al-glycolate spheres (NiMo/Al-SP) were synthesized through alcoholysis or hydrolysis treatments. The obtained samples were characterized by a complementary combination of X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), N physisorption, scanning electron microscopy (SEM), transmission electron microscopy (TEM), hydrogen temperature-programmed reduction (H-TPR), and pyridine Fourier transform infrared spectroscopy (Py FT-IR). In addition, the catalytic performances of the resultant catalysts were evaluated in the simultaneous HDS of dibenzothiophene (DBT) and HYD of naphthalene (DBT and naphthalene represent the sulfur-containing compounds and polycyoalkanes, respectively). The experimental results showed that, 71.22% DBT and 88.28% naphthalene were converted by NiMo/Al-SP(H) under the conditions of 270 °C temperature, 5 MPa H (initial pressure at room temperature) and 10 h reaction time. The design and preparation of NiMo/Al-SP provide an effective and novel pathway for the development of high-performance catalysts and production processes.
通过醇解或水解处理合成了由单分散多孔乙醇酸铝球体制成的新型复合材料（NiMo/Al-SP）。通过X射线衍射（XRD）、傅里叶变换红外光谱（FT-IR）、N物理吸附、扫描电子显微镜（SEM）、透射电子显微镜（TEM）、氢气程序升温还原（H-TPR）和吡啶傅里叶变换红外光谱（Py FT-IR）的互补组合对所得样品进行了表征。此外，在二苯并噻吩（DBT）的同步加氢脱硫（HDS）和萘的加氢（HYD）反应中评估了所得催化剂的催化性能（DBT和萘分别代表含硫化合物和多环烷烃）。实验结果表明，在270℃温度、5MPa氢气（室温初始压力）和10小时反应时间的条件下，NiMo/Al-SP(H)可使71.22%的DBT和88.28%的萘发生转化。NiMo/Al-SP的设计与制备为开发高性能催化剂及生产工艺提供了一条有效且新颖的途径。
