In recent years, petroleum industries are facing tremendous challenges due to more stringent environmental regulations coupled with increasing reliance on heavy crude oil sands derived bitumen. Syncrude Canada Ltd. currently produces 250,000 bbl/day of synthetic crude oil from the oil sand. The heavy gas oil, which is a major component of this synthetic crude oil contains higher amounts of sulfur ( 4 wt%) and nitrogen ( 0.4 wt. %), which need to be removed to meet specifications of downstream refining processes. Although the removal of sulfur is relatively easy, it is difficult to remove nitrogen from oil sands derived oils with above hydroteating catalyst. It is well known that the catalytic performance of Ni-Mo hydrotreating catalyst depends on the support used to a certain extent, since. Recently there have been growing interests in the synthesis of new molecular sieves extending the pore diameter to the mesoporous region. The mesoporous molecular sieves are obtained with various structures and pore diameters that can be controlled over a wide range (1.6-30nm). These new molecular sieves offer great potential for the shape-selective sensing, adsorption, and catalysis of large species that were limited by the micropores (typically less than 1nm) of zeolites. The present research proposal aims at the development of highly active Ni-Mo sulfide catalysts supported on high surface area, wide pore M-SBA-15 (M=Ti,Zr), mesoporous carbon and Carbon Nano Horns (CNHs) for hydrodenitrogenation (HDN) of Athabasca bitumen derived heavy gas oil (HGO). The high surface area, availability of a large variety of pore sizes, variable surface functional groups, easy metal recovery by the burning of the support, reduced coking propensity, and resistance to nitrogen poisoning are expected to increase the activity of the Ni-Mo catalysts. The use of these supports for NiMo hydrotreating catalyst will facilitate the removal of N and S atoms from the bulky molecules of heavy crude oil. This will help the participating industry, Syncrude Canada Ltd. to improve the quality of gas oil, which will meet specifications of downstream refining processes. This research also benefits Canada by efficient utilization of its vast oil resources.

近年来，由于更加严格的环境法规以及对重质原油砂衍生沥青的依赖日益增加，石油行业面临着巨大的挑战。 Syncrude Canada Ltd. 目前每天利用油砂生产 250,000 桶合成原油。 作为这种合成原油的主要成分的重瓦斯油含有较高量的硫（4 wt%）和氮（0.4 wt.%），需要将其去除以满足下游炼制工艺的规格。尽管脱硫相对容易，但用上述加氢催化剂从油砂衍生油中脱氮却很困难。 众所周知，Ni-Mo加氢精制催化剂的催化性能在一定程度上取决于所使用的载体。最近，人们对合成将孔径扩展到介孔区域的新型分子筛越来越感兴趣。 获得具有多种结构和孔径可在较宽范围（1.6-30nm）控制的介孔分子筛。 这些新型分子筛为受沸石微孔（通常小于 1 nm）限制的大型物质的择形传感、吸附和催化提供了巨大的潜力。 目前的研究计划旨在开发高表面积、大孔M-SBA-15（M=Ti,Zr）、介孔碳和碳纳米角（CNH）负载的高活性镍钼硫化物催化剂，用于加氢脱氮（HDN） ）的阿萨巴斯卡沥青衍生重瓦斯油（HGO）。 高表面积、多种孔径的可用性、可变的表面官能团、通过载体燃烧容易回收金属、降低焦化倾向和抗氮中毒预计将提高Ni-Mo催化剂的活性。 将这些载体用于 NiMo 加氢处理催化剂将有助于从重质原油的大分子中去除 N 和 S 原子。 这将帮助参与行业 Syncrude Canada Ltd. 提高瓦斯油的质量，从而满足下游炼油工艺的规范。 这项研究还通过有效利用其丰富的石油资源使加拿大受益。
