Abstract
Apparatuses, systems, and methods are disclosed for shale pyrolysis. A retort for shale pyrolysis may include a pyrolysis zone, a combustion zone, and a cool down zone. The pyrolysis zone may include one or more pyrolysis zone heat exchangers that transfer heat from a working fluid to shale for heating and pyrolyzing the shale. The combustion zone may include one or more injectors that inject oxygen to combust coke residue in the pyrolyzed shale. The cool down zone may include one or more cool down zone heat exchangers that cool the shale by transferring heat to the working fluid. In a further embodiment, the working fluid is circulated to heat the pyrolysis zone heat exchangers.
