Kerogen
Encyclopædia Britannica Article
complex mixture of compounds with large molecules containing mainly hydrogen and carbon but also oxygen, nitrogen, and sulfur. It is the organic component of oil shales, hence their alternative names of kerogen shales or kerogenites. Kerogen is insoluble in water; upon heating, it breaks down into recoverable gaseous and liquid substances resembling petroleum. It may consist of compacted organic material, such as algae and other low plant forms, pollen, spores and spore coats, and both adult and larval insects. The name was first applied to oil-bearing shales in Scotland.

Pyrolysis
From Wikipedia
Simple sketch of pyrolysis chemistry
Pyrolysis is the chemical decomposition of organic materials by heating in the absence of oxygen or any other reagents, except possibly steam.
It is used in chemical analysis to break down complex matter into simpler molecules for identification, for example by pyrolysis gas chromatography mass spectrometry.
In industry, it may be used to convert one single chemical; for example, ethylene dichloride is pyrolysed to vinyl chloride to make PVC. It may also be used to convert complex materials such as biomass or waste into substances that are either desirable or less harmful (e.g. - syngas).
Extreme pyrolysis, which leaves only carbon as the residue, is called carbonization. Pyrolysis is a special case of thermolysis.
