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. |

1. A method for retorting and extracting hydrocarbons from oil shale, the method comprising:
heating, for a first time, a heat transfer fluid, wherein the first volume of the heat transfer fluid comprises a first volume of at least one liquefied petroleum gas (LPG) component; moving, for a first time, a heat transfer fluid through a heat delivery loop, wherein a first portion of the heat transfer fluid is cracked while moving through the heat delivery loop, thereby forming a plurality of materials; retorting, using heat from the heat transfer fluid, an oil shale formation to produce recoverable hydrocarbons, wherein the recoverable hydrocarbons include a second volume of the at least one LPG component; removing a portion of the plurality of materials from the heat transfer fluid; heating, for a second time, the heat transfer fluid; and moving, for a second time, the heat transfer fluid through the heat delivery loop. |
