Effects of carbon black (CB) additives with dispersed MoS₂ catalysts (d-MoS₂) on the slurry phase hydrocracking (HCK) of vacuum residue (VR) were studied in an autoclave batch reactor at 693 K and 9.5 MPa H₂. For comparison, commercial NiMo catalysts supported on large and small pore volume Al₂O₃ (-LP, -SP) were also applied for the VR HCK. The structure of the catalysts was characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), and extended X-ray absorption fine structure (EXAFS). The dispersed MoS₂ (d-MoS₂) was observed to form nanosized single slabs of 8.4 nm, while in the presence of CB the particle size of the d-MoS₂-CB became even smaller (4.8 nm). A series of recycle runs of the VR HCK revealed high activity and stability of d-MoS₂-CB followed by d-MoS₂ > NiMo-LP > NiMo-SP. The kinetic analysis also demonstrated that the d-MoS₂-CB shows a high asphaltene conversion with minimizing coke formation.

在高压釜间歇反应器中，在693 K和9.5 MPa H _{2的条件下}，研究了分散有MoS ₂催化剂（d-MoS ₂）的炭黑（CB）添加剂对真空渣油（VR）的淤浆相加氢裂化（HCK）的影响。为了比较，也将负载在大和小孔体积的Al ₂ O ₃（-LP，-SP）上的市售NiMo催化剂用于VR HCK。通过透射电子显微镜（TEM），X射线衍射（XRD）和扩展的X射线吸收精细结构（EXAFS）来表征催化剂的结构。观察到分散的MoS ₂（d-MoS ₂）形成了8.4 nm的纳米单板，而在CB存在下d-MoS的粒径₂ -CB变得更小（4.8 nm）。VR HCK的一系列循环运行显示出d-MoS ₂ -CB的高活性和稳定性，然后是d-MoS ₂ > NiMo-LP> NiMo-SP。动力学分析还表明，d-MoS ₂ -CB显示出高的沥青质转化率，并使焦炭的形成最小化。
