    摘要: Some embodiments relate to a method for producing, from sulfur-rich type IIs kerogen, a sweetened synthetic crude having a sulfur concentration of at most 1% wt/wt, a nitrogen concentration of at most 0.2% wt/wt and an API gravity of at least 30°. Hydrotreating is performed under only low-severity conditions of at most about 350 degrees Celsius and a maximum pressure of at most 120 atmospheres. In some embodiments, the feedstock to the hydrotreater comprises hydrocarbon pyrolysis liquids generated primarily by low temperature pyrolysis of the sulfur-rich type IIs kerogen. For example, the feedstock may be rich in easier-to-hydrotreat heterocyclic species. In some embodiments, it is possible to optimize the pyrolysis process by monitoring relative concentrations of the easier-to-hydrotreat heterocyclics and the harder-to-treat heterocyclics.

    摘要: Hydrocarbon-containing rocks comprising type IIs kerogen are introduced into an excavated enclosure (e.g. a pit or an impoundment) to form a bed of rocks therein. One or more heaters (e.g. molten salt heaters) are operated to pyrolyze type IIs kerogen of the rocks. In some embodiments, a hydrocarbon reflux loop is maintained within the enclosure to convectively heat the type IIs-kerogen-containing rocks by boiling hydrocarbon liquids from a reservoir at the bottom of the enclosure so that vapor passes to the top of the enclosure, condenses, and falls back through the bed. Alternatively or additionally, the rocks may be heated by heaters embedded within wall(s) and/or a floor of the enclosure.
