以预处理后的催化裂化催化剂残渣（PFC 3 R）为载体，以聚乙烯吡咯烷酮（PVP）为分散剂，合成了镍基催化剂（Ni-PVP/PFC 3 R），并应用于C9石油树脂（C9 PR）加氢反应。为了比较，以相同的方式制备不含PVP的Ni催化剂（Ni/PFC 3R）。结果表明，Ni-PVP/PFC 3R催化剂具有较高的活性和较好的稳定性。采用X射线衍射、扫描电子显微镜、程序升温还原/程序升温脱附、傅立叶变换红外光谱和Brunauer-Emmett-Teller方法对催化剂进行了表征。在PVP存在下，催化剂的晶粒尺寸较小，Ni物种与PFC 3R载体之间的相互作用较强。考察了Ni负载量、氢气压力、反应温度和反应时间对Ni-PVP/PFC 3R催化剂上C9 PR加氢反应的影响。在以下条件下溴值降低至1.25：镍含量为12wt%，PVP量为1.5wt%，温度为270°C，H2压力为8 MPa，反应时间为240分钟。
A Ni-based catalyst (Ni-PVP/PFC3R) with polyvinyl pyrrolidone (PVP) as a dispersant supported in a pretreated fluid catalytic cracking catalyst residue (PFC3R) was synthesized and applied to C9 petroleum resin (C9 PR) hydrogenation. For comparison, a Ni catalyst without PVP (Ni/PFC3R) was prepared in the same way. Ni-PVP/PFC3R exhibited higher activity and better stability. The catalysts were characterized by X-ray diffraction, scanning electron microscope, H2-temperature programmed reduction/temperature programmed desorption, Fourier transform infrared spectroscopy and the Brunauer–Emmett–Teller method. The catalysts had a smaller crystallite size and stronger interactions between the Ni species and the PFC3R support in the presence of PVP. The effects of nickel loading, H2 pressure, temperature and reaction time for C9 PR hydrogenation over Ni-PVP/PFC3R were investigated. The bromine number was reduced to 1.25 under the following conditions: nickel content of 12 wt%, PVP amount of 1.5 wt%, temperature of 270°C, H2 pressure of 8 MPa and reaction time of 240 min.
