Quinoline and acridine, the basic nitrogencontaining molecules present in heavy oils, are preferably adsorbed on the Niedge surface through the lone pair electrons of the nitrogen atom, which produces relatively high adsorption energies (△Ea= 16–26 kcal mol1 ). Indole and carbazole, the nonbasic nitrogencontaining molecules, primarily interact with the NiMoS catalyst edge surface through the πelectrons of the carbon atoms. While indole preferentially adsorbs on the NiMoS surface through the βcarbon of the pyrrolic ring (△Ea= 19 kcal mol1 ), carbazole primarily interacts with the NiMoS surface through the phenyl rings (△Ea = 13 kcal mol1). The relative adsorptivities and energetically preferred adsorption modes of the nitrogencontaining molecules in heavy oils can 山東科技大學本科畢業(yè)設計（論文） 40 provide insights into experimental observations about hydrodenitrogenation (HDN) kiics and reaction pathways.

Introduction The increasing demand for processing heavy oils and vacuum residue, which contain significantly more nitrogen pounds than conventional light crude oils, requires the development of hydrotreating catalysts with higher hydrodenitrogenation (HDN) activity. In order to develop new hydrotreating catalysts with high activity to remove refractory nitrogen pounds present in heavy oils, a detailed understanding of HDN catalysis, including the structure of the catalysts, the electronic configurations of the nitrogen pounds, and the adsorption and reaction mechanisms of basic and nonbasic nitrogen pounds on catalyst surfaces, is required. Molybdenumbased sulfides are widely used in the oil refining industry as hydrotreating catalysts to remove sulfur and nitrogen from heavy oils. The active phase on these hydrotreating catalysts has a MoS2like structure, and active sites are located at edge surfaces of the MoS2[1,2]. Due to extensive experimental and theoretical research, a good understanding of the structure of the active phase at the atomic level and the location of promoters (nickel and cobalt) in the active phase has been achieved. For unpromoted MoS2, the（ ?010） Sedge and（ 10 ?0） Moedge are normally covered by bridge sulfur 山東科技大學本科畢業(yè)設計（論文） 41 atoms and have very few sulfur vacancies at reaction conditions[3–5]. In the promoted catalysts, cobalt prefers to incorporate into the Sedge and nickel to the Moedge of MoS2 , and the promoted edge surfaces have more vacant sites under typical hydrotreating reaction conditions[6–8]. Most nitrogen present in heavy crude oils is in the form of heterocyclic anonitrogen pounds containing basic (pyridinic) or nonbasic (pyrrolic) ring structures[9]. Non basic nitrogen pounds are a significant fraction of the total nitrogen content in heavy oils[10,11]. These nonbas
