Canada has approximately 2400 billion barrels of bitumen that is considered as the world's largest **oilsands deposits. Approximately 5 billion barrels of bitumen were already recovered and **approximately 174 billion barrels of bitumen are recoverable by using current technology. The **conventional technology includes surface mining and hot water extraction and in-situ bitumen **extraction such as cyclic steam simulation and steam assisted gravity drainage (SAGD). Although **these processes are using commercially, the extensive mining and extraction of bitumen from oil **sands has made the environment more vulnerable including a large amount of water consumption, land disturbance, tailings ponds footprint and green-house gas emissions. Tailings treatment has caused increasing concern in recent years among these issues. More research is necessary to develop more sustainable and environmentally viable technology to recover bitumen from oilsands deposits. 3P **Technology Corporation has developed a process to separate the bitumen, clay-water and sands by **using modulated electricity at 30 Celsius without adding any chemicals, heat and agitation to the **material. This is called the pulse plasma process, hereafter called 3P. Following 3P treatment, **the bitumen floats to the top of the vessel as foam, clay-water stay as a middle layer, above the **sand layer. The bitumen recovered has comparable properties to the conventional bitumen. However, **the propose technology is in the early stage and it requires more systematic study to advance the **technology in the field. The goal of this project is to determine chemical changes occur in the **bitumen because of the 3P's pulse plasma process. Different analytical techniques such as 1H NMR **(proton nuclear magnetic resonance) spectrometer, 13C NMR (carbon NMR), FTIR (Fourier transform **infrared spectrometer, elemental analyser, density meter, refractometer, ESR (electron spin **resonance) spectrometer will be used to investigate the chemical changes. ********

加拿大拥有约24000亿桶沥青，被认为是世界上最大的**油砂矿床。大约50亿桶沥青已经被回收，**使用当前技术可回收约1740亿桶沥青。 **常规技术包括表面采矿和热水提取以及原位沥青**提取，例如环状蒸汽模拟和蒸汽辅助重力排水（SAGD）。尽管这些过程在商业上正在使用，但是从油中大量的采矿和提取沥青**砂使环境更加脆弱，包括大量的用水量，土地干扰，尾矿池塘足迹和绿色房屋气体的排放。近年来，尾矿治疗引起了越来越多的关注。需要更多的研究来开发更可持续和环保的技术，以从油砂矿床中收回沥青。 3P **技术公司已经开发了一个过程，可以使用30摄氏度的调制电力通过**将沥青，粘土水和沙子分开，而无需向**材料添加任何化学物质，热和搅动。这就是称为脉冲等离子体过程，此后称为3p。 3p处理后，**沥青以泡沫为泡沫的顶部，粘土水作为中间层保持**砂层上方。 回收的沥青与常规沥青具有可比的特性。但是，**建议的技术处于早期阶段，它需要更多的系统研究来推进该领域的技术。该项目的目的是确定由于3P的脉冲等离子体过程，**沥青发生了化学变化。不同的分析技术，例如1H NMR **（Proton核磁共振）光谱仪，13C NMR（Carbon NMR），FTIR（傅立叶变换**红外光谱仪，元素分析仪，密度表，折射率计，ESR，ESR，ESR（电子旋转**旋转）将用于调查化学变化。
