This CRD project aims to develop cost-effective technological solutions to recycling and recovery of valuable products from industrial residues and waste streams - petroleum coke, oil sands process water and tailings. Canada is blessed with the second largest proven reserve of oil in the world, mainly in oil sands deposits in Alberta. In the oil sands industry, an average of 3 barrels of fresh water is needed for every barrel of oil produced from surface mines. A large fraction of the process water ends up in the tailings produced during bitumen extraction. The oil sands process water and tailings contain organics from the bitumen separation process (e.g., naphthenic acids (NAs) and bitumen/aromatic hydrocarbons), among which NAs are the major constituent in terms of both concentration and toxicity. Treatment of the process water has been a critical issue for the oil sands industry, with respect to sustainable oil production and freshwater resource protection. In this project, we will closely collaborate with Newalta Corporation to develop innovative engineered environmental solutions to valorization of petroleum coke as an inexpensive but effective adsorbent (highly porous activated carbon (HPAC) materials with tailored structure/surface properties) for treatment of oil sand process water and tailings. The removal and recovery of NAs/bitumen using the HPAC materials produced from residues (petroleum coke) could not only reduce fresh water consumption and enable recovery of residual organics from process water and tailings, but also turn residue petroleum coke into valuable products (adsorbents) and hence, reduce the need for disposal. It is thus anticipated that the outcome of this CRD project would greatly impact on both the oil sands industry (for cleaner fossil fuels production) and Newalta (for development of new technologies for organics removal from waste water, valorization and resource recovery).

这个CRD项目旨在开发具有成本效益的技术解决方案，以从工业残留物和废物流中回收和回收有价值的产品 - 石油焦炭，油砂过程水和尾矿。加拿大拥有世界第二大的石油储备，主要是艾伯塔省的油砂矿床。在油砂行业中，每桶从地面矿山生产的石油平均需要3桶淡水。一小部分工艺水最终在沥青提取过程中产生的尾矿。油砂处理水和尾矿包含来自沥青分离过程（例如，环甲酸（NAS）和沥青/芳族碳氢化合物）的有机物，其中NAS在浓度和毒性方面都是主要成分。对于可持续的石油生产和淡水资源保护，对流程水的处理一直是油砂行业的关键问题。在该项目中，我们将与Newalta Corporation紧密合作，以开发创新的工程环境解决方案，以使石油焦炭成为一种廉价但有效的吸附剂（高度多孔活性碳（HPAC）材料，具有量身定制的结构/表面性能），以处理油砂水和尾矿的处理。使用残留物（石油焦炭）产生的HPAC材料清除和回收NAS/沥青剂不仅可以减少淡水消耗，还可以从过程水和尾矿中恢复残留有机物，还可以将残留的石油焦炭转变为有价值的产品（Adsorbents），从而减少了出境的需求。因此，预计该CRD项目的结果将极大地影响油砂行业（用于清洁化石燃料的生产）和Newalta（用于开发从废水，价值和资源回收中去除有机物的新技术）。
