The research program will focus on investigating the catalytic phenomena involved in hydrodenitrogenation reactions over sulfided and unsulfided Ni-Mo catalysts. The catalysts to be used in this study will be synthesized by three different techniques, namely, homogeneous sulfide precipitation, impregnated thiosalt decomposition and intercalation of nickel and molybdenum cations in clay matrices. Catalyst characterization will be performed using various techniques including BET surface area and pore size distribution analysis, X-ray diffraction, scanning and transmission electron microscopy, energy dispersive X-ray analysis, laser Raman Spectroscopy and Raman microprobe and X-ray photoelectron spectroscopy. Thermal analysis techniques will also be used through temperature-programmed reduction, desorption and sulfidation studies. In addition to ambient characterization of the catalysts, in-situ characterization techniques will also be adopted using a laser Raman spectrometer and a specially designed in-situ Raman cell. The changes that take place in the catalyst during oxidation, reduction, sulfidation, reaction and deactivation processes will be examined in-situ. These studies will be used to investigate the nature of the active form of the catalyst and the catalyst support interactions. In addition to examining the reaction network, the effect of reaction parameters such as hydrogen partial pressure, reaction temperature and pressure and the effect of substituents will also be investigated. Finally, isotopic labelling techniques will be combined with kinetic studies and in-situ laser Raman spectroscopy studies to gain insight into the catalytic phenomena involved in hydrodenitrogenation reactions.

该研究计划将重点研究硫化和未硫化 Ni-Mo 催化剂上加氢脱氮反应的催化现象。 本研究中使用的催化剂将通过三种不同的技术合成，即均相硫化物沉淀、浸渍硫盐分解以及镍和钼阳离子在粘土基体中的插层。 催化剂表征将使用各种技术进行，包括 BET 表面积和孔径分布分析、X 射线衍射、扫描和透射电子显微镜、能量色散 X 射线分析、激光拉曼光谱、拉曼微探针和 X 射线光电子能谱。 热分析技术也将用于程序升温还原、解吸和硫化研究。 除了催化剂的环境表征外，还将采用激光拉曼光谱仪和专门设计的原位拉曼池进行原位表征技术。 催化剂在氧化、还原、硫化、反应和失活过程中发生的变化将被现场检查。 这些研究将用于研究催化剂活性形式的性质和催化剂载体相互作用。 除了检查反应网络外，还将研究氢分压、反应温度和压力等反应参数的影响以及取代基的影响。 最后，同位素标记技术将与动力学研究和原位激光拉曼光谱研究相结合，以深入了解加氢脱氮反应中涉及的催化现象。
