High-performance, low-cost porous carbons from oil sands petroleum coke

采用废物处理废物战略，该项目的目标是开发新技术，使大规模生产高性能、负担得起的多孔碳从主要的工业废物-油砂石油焦（OSPC）。ospc衍生的多孔碳将被用于油砂行业，以减少对淡水的依赖。从2010年到2035年，阿萨巴斯卡油砂地区的开发将为加拿大经济贡献2.28万亿美元。在从油砂中开采沥青生产合成原油（SCO）的同时，也产生了大量的油砂石油焦（OSPC）和油砂工艺影响水（OSPW）。每生产一桶上合组织原油，需要在现场生产和储存约20公斤上合组织原油，现有库存超过7000万吨。OSPC具有独特的高杂质含量，特别是硫和重金属，这阻碍了其作为固体燃料的应用。由于艾伯塔省政府的“零排放”政策，超过7亿立方米的有毒OSPW储存在现场。在OSPW中发现了四类污染物——悬浮固体、自由相碳氢化合物、溶解有机物和溶解固体。溶解的有机物是造成OSPW毒性的原因。如果价格合理，ospc衍生的多孔碳材料将是去除OSPW中溶解有机物的理想材料。多孔碳是一种成熟的市政用水和消费用水净化技术。然而，由于需要大量多孔碳的高污染水平，商用多孔碳对于处理工业废水来说过于昂贵。该项目解决了ospc衍生多孔碳的制造过程的成本效益和性能问题，将使多孔碳的生产变得经济实惠，并且可以大量获得。除了预期利用ospc衍生碳处理OSPW之外，人们还可以设想其他大规模应用，如土地复垦。该项目将同时为加拿大油砂行业及其他行业带来环境和经济效益。

Applying a waste-treat-waste strategy, the goal of this project is to develop new technologies that enable large-scale manufacturing of high-performance, affordable porous carbons from a major industry waste - oil sands petroleum coke (OSPC). The OSPC-derived porous carbons will be used by the oil sands industry to reduce its dependence on fresh water. The developments in Athabasca oil sands region will contribute $2.28 trillion to Canada's economy from 2010 to 2035. While the increased quantities of synthetic crude oil (SCO) are being produced from the bitumen mined from oil sands, large amounts of oil sands petroleum coke (OSPC) and oil sands process-affected water (OSPW) are also generated. To produce one barrel of SCO, about 20kg of OSPC are generated and stored on site, adding to the existing stockpiles of over 70 million metric tons. The OSPC has uniquely high impurity contents, particularly sulphur and heavy metals, which has hindered its application as a solid fuel. A result of the Alberta government's "zero discharge" policy, over 700 million cubic meters of toxic OSPW are stored on-site. Four groups of contaminants are found in OSPW- suspended solids, free phase hydrocarbons, dissolved organics and dissolved solids. Dissolved organics are responsible for the toxicity of OSPW. If made affordable, OSPC-derived porous carbon materials will be ideal for removing dissolved organics in OSPW. Using porous carbon is a mature technology for water purification in municipal and consumer applications. Commercial porous carbon, however, is too expensive for treating industrial waste waters due to high contamination levels that demand a large amount of porous carbons. Addressing both cost-effectiveness of the manufacturing process and performance of OSPC-derived porous carbons, this project will enable the creation of porous carbons that are affordable and readily available in large quantities. In addition to the anticipated utilization of the OSPC-derived carbons in treating OSPW, one could also envisage other large-scale applications such as land reclamation. The project will simultaneously deliver environmental and economic benefits to Canada's oil sand industry and beyond.
