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，由于更严格的环境法规，加上对重的原油砂衍生沥青的依赖，因此石油行业面临巨大的挑战。 Syncrude Canada Ltd.目前从油砂中生产250,000 bbl/天的合成原油。 重气油是该合成原油的主要组成部分，其中含有更高量的硫（4 wt％）和氮（0.4 wt。％），需要去除以满足下游精炼过程的规格。尽管去除硫的含量相对容易，但很难从衍生油的油砂中去除氮，并具有高于水力发电催化剂的油。 众所周知，Ni-MO氢化催化剂的催化性能取决于一定程度上的支撑。最近，对新分子筛的合成的兴趣越来越大，将孔直径延伸到介孔区域。 介孔分子筛的用各种结构和孔直径获得，可以在宽范围内控制（1.6-30nm）。 这些新的分子筛子为形状选择性感测，吸附和催化提供了巨大的潜力，这些物种受到微孔（通常小于1nm）的沸石限制的大物种。 目前的研究建议旨在开发高表面积，宽孔M-SBA-15（M = Ti，Zr），介孔碳和碳纳米角（CNHS）的高度活性Ni-MO硫化物催化剂（HDN）。 高表面积，各种孔径的可用性，可变的表面官能团，通过燃烧燃烧而轻松的金属恢复，减少的焦化倾向以及对氮中毒的耐药性有望增加Ni-MO催化剂的活性。 这些支撑物用于NIMO Hydotreting催化剂将有助于从重物的笨重分子中去除N和S原子。 这将有助于参与行业Syncrude Canada Ltd.提高气体油的质量，这将符合下游炼油过程的规格。 这项研究还通过有效利用其庞大的石油资源来使加拿大受益。
