Coal Tar

Coal tar is the condensable liquid fraction produced when coal is subjected to Destructive Distillation. In the context of Low-Temperature Carbonization (LTC) and the karrick-process, it is the liquid product stream that the source dossier counts toward its claimed oil yield.

Role in the source

The source presents the liquid condensate — referred to as crude oil or tar oil — as a primary valuable output of low-temperature carbonization, alongside combustible gas and Semi-Coke. The claimed figure of approximately 30 gallons of crude oil per ton of coal refers to this liquid fraction.

Limits of the source

The ingested material supplies no assay data, boiling-range distribution, or upgrading pathway for the condensate. The yield figure is a dossier assertion and is treated as such at Karrick Claims vs. Evidence: The Dossier's Assertions and the Absence of Test Data.

Coal Carbonization vs. Coal Liquefaction

Coal conversion routes differ in what they optimize. Carbonization heats coal to drive off volatiles and leave a solid residue; liquefaction and hydrogenation aim primarily at liquid products.

Destructive Distillation

Destructive distillation is the thermal decomposition of a solid organic material — coal, oil shale, wood, or similar — in the absence or near-absence of oxygen. Because combustion is suppressed, the material does not burn; instead it breaks down into volatile and solid fractions.

Low-Temperature Carbonization (LTC)

Low-temperature carbonization is the thermal treatment (destructive distillation / pyrolysis) of coal or oil shale at temperatures below those used in conventional coking — broadly in the 450–700 °C range — to drive off volatile matter and leave a solid char or semi-coke, together with a condensable tar/oil fraction and a combus

Semi-Coke

Semi-coke (also called char) is the solid carbon-rich residue left after the volatile fraction of coal or oil shale has been driven off by Destructive Distillation . It is the solid co-product of Low-Temperature Carbonization (LTC) and, by extension, of the karrick-process as described in the source dossier.
