The oil sands currently provide 46% of Canada's oil production; this is expected to rise to 80% by 2020. The environmental challenges that face oil sands production stem from the large amounts of energy and water required for production and upgrading processes, and the large amounts of heavy hydrocarbon waste, wastewater, and gaseous emissions that are generated. Nanotechnology offers great opportunities to address these issues through the development of greener processes that can de-intensify energy and water use and that can eliminate byproduct and waste generation. In this context, nanoparticles represent one of the most promising solutions to a number of challenges in oil sands extraction and upgrading, as they act as quasi-homogeneous adsorbents/catalysts. This research program seeks to develop the concept of "nanosorbcats." These are naturally occurring iron-silicate materials-based nanoparticles that can adsorb and remove waste heavy polar hydrocarbons from heavy oil, and subsequently catalytically upgrade them into light utilizable distillates, thus acting as alternatives to thermal cracking (coking). The preparation of nanosorbcats by hydrothermal method is proposed. The proper range of synthesis conditions will be studied and defined, and the effects of composition and particle size on adsorptive removal of polar hydrocarbons from heavy oil will be tested. Catalytic hydroprocessing of the adsorbed polar heavy hydrocarbons will be carried out in a pilot plant setup to convert the waste heavy polar hydrocarbons into light utilizable distillates. This research shall provide opportunities for the oil industry to transform current commercial practices into processes with improved economic and environmental performance. *****

该油砂目前可提供加拿大石油生产的46％；预计到2020年将上升到80％。面临油砂生产的环境挑战源于生产和升级过程所需的大量能源和水，以及大量的大量碳氢化合物废物，废水以及产生的气态排放。纳米技术通过开发较绿色的过程，可以消除能源和用水，并消除副产品和废物产生，从而提供了很好的机会来解决这些问题。在这种情况下，纳米颗粒代表了油砂提取和升级中许多挑战的最有希望的解决方案之一，因为它们充当准同质吸附剂/催化剂。该研究计划旨在发展“纳米虫”的概念。这些是天然存在的铁硅酸盐材料基纳米颗粒，可以吸附并从重油中消除浪费重的极性烃，然后催化将它们升级到可轻松的蒸馏液中，从而充当热裂（Coking）的替代方案。提出了通过水热法制备纳米菌。将研究和定义适当的合成条件范围，并将测试组成和粒径对吸附性去除极性碳氢化合物的影响。吸附的极性重烃的催化氢处理将在试验厂设置中进行，以将浪费重的极性碳氢化合物转化为可轻松利用的蒸馏液。这项研究应为石油工业提供机会，将当前的商业实践转变为经济和环境绩效改善的过程。 *****
