摘要： Hydrocarbon liquids are recovered from carbonaceous materials such as tar sands utilizing a separation reagent formed in situ by reacting polar resin components of tar sands with an inorganic base such as sodium silicate in sonicated aqueous solution in absence of an organic solvent to form a surfactant. Under the influence of sonication a microemulsion of polar-external micelles forms.When tar sands are added to the sonicated separation reagent, the surfactant penetrates the bitumen. Metal ions complex with the polar groups and aid in removing the bitumen from the sand particles. The polar-organic asphaltene materials are carried into the aqueous phase by the anion and stabilized within the micelle structure. The lighter, non-polar hydrocarbon oil fraction separate from the emulsion and rise to the top and is recovered by skimming. The heavier asphaltenes and preasphaltenes complex with the polyvalent metals to form charcoal-like agglomerates which settle to the bottom of the treatment tank. The rate of separation of bitumen can be significantly increased by adding a small amount of a free radical initiator such as benzoyl peroxide to the separation reagent.
摘要翻译：烃类液体是从含碳物质如沥青砂中回收的，利用在无有机溶剂的条件下，将超临界水溶液中的焦油砂的极性树脂成分与无机碱如硅酸钠在原位形成的分离剂一起回收，形成表面活性剂。在超声处理的影响下，形成极性 - 外部胶束的微乳液。当沥青砂添加到超声处理的分离试剂中时，表面活性剂渗透沥青。金属离子与极性基团复合，有助于从砂粒中除去沥青。极性有机沥青质材料通过阴离子运送到水相中并稳定在胶束结构内。较轻的非极性烃油馏分与乳液分离并升至顶部，并通过撇去回收。较重的沥青质和预沥青质与多价金属复合，形成沉淀到处理槽底部的类似炭的附聚物。通过向分离试剂中加入少量的过氧化苯甲酰等自由基引发剂可以显着提高沥青的分离速度。
