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.

Products

Volatile fraction — condensable tars and oils, plus non-condensable combustible gas.
Solid residue — a carbon-rich char or coke.

Role in this wiki

Destructive distillation is the underlying mechanism of Low-Temperature Carbonization (LTC) and therefore of the karrick-process described in the source dossier. The distinction between low-temperature and high-temperature operation is a matter of the working temperature range, which determines the proportions and character of the products obtained.

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.

Coal Liquefaction

Coal liquefaction is the conversion of solid coal into liquid hydrocarbon products. It is the broader category within which the karrick-process and Low-Temperature Carbonization (LTC) sit.

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.

Karrick Process

The Karrick process is a named low-temperature carbonization (LTC) route for coal, associated with Lewis Cass Karrick and documented in a source dossier. It heats coal below conventional coking temperatures to drive off volatiles, leaving a solid char together with condensable tar/oil and a combustible gas stream.

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.
