Deep denitrogenation of transportation fuels by selective adsorption

加拿大有大量的重油和油砂沥青储量。开发这些巨大的储量，为化学和石化工业提供清洁燃料、能源和原料，将为加拿大带来巨大的经济效益。然而，这些重油和沥青沉积物含有大量的杂原子，必须去除。有机硫/氮化合物燃烧后可转化为SOx和NOx，形成酸雨。新规定要求柴油的含硫量从以前的500ppm降至15ppm，并将在2011年进一步降至10ppm。满足并超过新的燃料规格对炼油商来说是一个重大挑战，他们希望以尽可能低的成本实现这一目标。此外，现有的加氢处理技术很难将硫化合物去除到15 ppm以下。另一方面，氮化合物的减少可以显著提高脱硫性能。提出的研究重点是开发一种新的吸附剂，用于选择性地去除液态烃燃料中的N化合物。这将有助于参与行业，帝国石油有限公司和其他加拿大炼油厂经济地满足新的立法。

Canada has large reserves of heavy oil and oilsands bitumen. Development of these vast reserves to provide clean fuel, energy and feedstock for the chemical and petrochemical industry will provide significant economic benefit for Canada. However, these heavy oil and bitumen deposits contain a large amount of hetero atoms that have to be removed. Organic sulfur/nitrogen compounds, upon combustion, can be converted into SOx and NOx, which result in acid rain. The new regulations on diesel fuels require sulfur content at the pump of 15 ppm, down from the previous 500 ppm, and it will be further reduced to 10 ppm in 2011. Meeting and exceeding the new fuel specifications presents a significant challenge to petroleum refiners, who want to achieve this at the lowest possible cost. As well, the existing hydrotreating technologies are difficult to remove sulfur compounds to less than 15 ppm. On the other hand, reduction in nitrogen compounds can significantly improve the performance of sulfur removal. The proposed research will focus on the development of a new adsorbent for selective removal of N compounds from liquid hydrocarbon fuels. This will help the participating industry, Imperial Oil Ltd. and other Canadian refineries to economically meet the new legislation.
