摘要： Embodiments of a method and a system for recovering energy, materials or both from asphaltene-containing tailings are disclosed. The asphaltene-containing tailings can be generated, for example, from a process for recovering hydrocarbons from oil sand. Embodiments of the method can include a flotation separation and a hydrophobic agglomeration separation. Flotation can be used to separate the asphaltene-containing tailings into an asphaltene-rich froth and an asphaltene-depleted aqueous phase. The asphaltene-rich froth, or an asphaltene-rich slurry formed from the asphaltene-rich froth, then can be separated into a heavy mineral concentrate and a light tailings. Hydrophobic agglomeration can be used to recover an asphaltene concentrate from the light tailings. Another flotation separation can be included to remove sulfur-containing minerals from the heavy mineral concentrate. Oxygen-containing minerals also can be recovered from the heavy mineral concentrate. Water removed by the various separation steps can be recycled and its heat energy recovered.

摘要： A method for processing asphaltenes is disclosed. The method can include separating asphaltenes from an asphaltene-containing composition and oxidizing the separated asphaltenes to form oxidation products. Alternatively, the method can include oxidizing asphaltenes within an asphaltene-containing composition without first separating the asphaltenes. Once formed, the oxidation products can be combined with other hydrocarbons. The amount of oxidation can be limited to an amount sufficient to produce a mixture suitable for the desired application. This method can be used to upgrade asphaltenes from a variety of sources, including oil sands. The oxidation step can be performed, for example, by introducing an oxidizing agent and, in some cases, a catalyst into the asphaltenes. A solvent or miscibility agent also can be introduced to improve mixing between the oxidizing agent and the asphaltenes.

摘要： A hydrometallurgical process is provided to electrogalvanize steel, utilizing primary and secondary zinc sources. The process consists of leaching the feed in a mildly acidic solution. The zinc is selectively recovered from the leach liquor in a solvent extraction system and thereafter stripped from the solvent using a stronger acidic solution to provide a strip solution which is fed to an electrogalvanizing bath for electrogalvanizing steel products, e.g., sheet steel, using insoluble anodes. Acidic solutions and organic solvent are recycled in the process.

摘要： A method for obtaining heavy oil is disclosed. The method includes mixing a material including heavy oil (e.g., oil sand) with a solvent including biodiesel to form a mixture and separating the mixture into a oil-enriched solvent phase and a residual sand phase. The method also can include introducing a solvent including biodiesel into an in-situ geological formation including heavy oil and collecting a mixture including biodiesel and heavy oil from the formation. For example, the mixture can be collected after the solvent travels through at least a portion of the formation by gravity. A method for producing biodiesel also is disclosed. The method includes microbially digesting asphaltenes to form a liquor including a fatty acid and reacting the fatty acid with an alcohol to produce biodiesel. This method can be used to convert petroleum asphaltenes and/or coal asphaltenes into biodiesel.

摘要： A process for the biological treatment of bitumen froth tailings produced from a tar sands treatment and bitumen froth extraction process is disclosed. In this process bitumen froth tailings, containing native hydrocarbon metabolizing microorganisms, are mixed with a growth media to form an inoculum which is then incubated under isothermal conditions for an amount of time to produce a mixed bacterial culture containing bioliquor and a water product containing a reduced amount of asphaltenes as well as solids such as clays and sands. The bioliquor produced in this process is then utilized in the initial tar sands conditioning process from which bitumen froth is produced as well as in the initial tar sands mining process via bioliquor injection directly into the tar sands formation. Because the mixed bacterial culture is made up of a number of hydrocarbon metabolizing microorganisms, the bioliquor is also used in the degradation of the asphaltenes. The treatment results in a process for decreasing the amount of waste produced in bitumen extraction processes. Furthermore, because the invention utilizes a biosurfactant containing bioliquor in the initial tar sands conditioning process, bitumen froth can be produced at lower temperatures and without requiring the use of caustic soda, as is conventionally practiced. Thus, the present invention advantageously avoids the production of tailings sludges caused by clay dispersion.
摘要翻译： 公开了一种由焦油砂处理和沥青泡沫提取方法生产的沥青泡沫尾矿的生物处理方法。 在这个过程中，将含有天然烃代谢微生物的沥青尾矿与生长培养基混合以形成接种物，然后在等温条件下孵育一段时间以产生含有生物分解液的混合细菌培养物和含有还原 沥青质量以及固体，如粘土和沙子。 然后在该过程中生产的生物分子被用于生产沥青泡沫的初始焦油砂调节过程中，以及在初始焦油砂矿开采过程中，通过直接注入沥青砂组合中的生物混合物注入。 因为混合的细菌培养物由许多烃代谢微生物组成，所以生物分子也用于沥青质的降解。 该处理产生了减少在沥青提取过程中产生的废物量的过程。 此外，由于本发明在初始焦油砂调理过程中利用含有生物分子的生物表面活性剂，所以可以在较低温度下生产沥青泡沫，而不需要使用苛性钠，如常规实践的那样。 因此，本发明有利地避免了由粘土分散体引起的尾渣污泥的产生。
