Abstract
Devices, systems, and processes are provided for retorting and extracting hydrocarbons from oil shale. A heat transfer fluid includes at least one liquefied petroleum gas (LPG) component such as, for example, propane or butane. The heat transfer fluid moves through a heat delivery loop to retort oil shale, thereby facilitating the production of recoverable hydrocarbons. While the heat transfer fluid moves through the heat delivery loop, cracking of a portion of the heat transfer fluid may produce various hydrocarbon materials that may be provided to a product stream.
