Oil shale retorting. [hot spent shale used as heat source]
Patent
·
OSTI ID:7343944
Oil shale is retorted in a vertical reactor that is separated into discrete zones. Sensible heat from hot spent shale is used for the thermal decomposition of kerogen, which is done in the absence of air, thus liberating a maximum of desirable products without loss of product by combustion and avoiding the necessity of separating and removing gaseous combustion products from the volatilized kerogen. The carbonaceous residue on the retorted shale is combusted to furnish the sensible heat used in the various parts of the process.
