摘要:
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.

We provide a process, comprising oligomerizing one or more olefins having a boiling point less than 82° C. in a presence of an ionic liquid catalyst and one or more C5+ alpha olefins in a reactor to produce a base oil having a kinematic viscosity at 100° C. of 36 mm2/s or higher and a VI greater than 55; and wherein the one or more olefins having the boiling point less than 82° C. comprise greater than 50 wt % of a total mixture of olefins fed to the reactor. We provide a process, comprising oligomerizing olefins having a low boiling point in a presence of an ionic liquid catalyst and a mixture of C5+ alpha olefins derived from waste plastic to produce a base oil having a kinematic viscosity at 40° C. greater than 1100 mm2/s and a VI greater than 55. We also provide a base oil made by the process.
