    • Disclosed herein are methods for isolating heavy saturated hydrocarbons from a subsurface shale formation comprising kerogen and an extractible organics component. These methods can be used to provide a bright stock product. The process comprises extracting an extractible organics component from subsurface shale formations comprising kerogen and the extractible organics component in an inorganic matrix and isolating a heavy hydrocarbon fraction comprising saturated beta-carotene. The methods utilize a hydrocarbon solvent to at least partially solubilize the extractible organics component. Among other factors, these processes are based on the discovery that the extractible organics is composed of a heavy hydrocarbon component containing saturated beta-carotene. The saturated beta-carotene product is a valuable commercial product. The presently disclosed processes are more environmentally benign, more economical, and more efficient in producing commercial products and in providing access to kerogen.
    • 本文公开了从含有干酪根和可提取的有机物组分的地下页岩层中分离重饱和烃的方法。 这些方法可用于提供光亮的原料产品。 该方法包括从含有无机基质中的干酪根和可萃取的有机物组分的地下页岩层中提取可提取的有机物组分,并分离包含饱和β-胡萝卜素的重质烃馏分。 该方法利用烃溶剂至少部分增溶可萃取的有机物成分。 除其他因素之外,这些方法是基于以下发现:可萃取的有机物由含有饱和β-胡萝卜素的重质烃组分组成。 饱和β-胡萝卜素产品是有价值的商业产品。 目前公开的方法在生产商业产品和提供对油母质的接触方面更环保,更经济,更有效。
