[Extract] Kerogen is the solid, high molecular-weight fraction of sedimentary organic matter (OM) that is insoluble in organic solvents (e.g. chloroform) as oppoosed to the soluble fraction called bitumen. Kerogen is a macromolecule of condensed cyclic nuclei linked by heteroatomic bonds or aliphatic chains.

Kerogen Chemistry 9. Removal of Kerogen Radicals and Their Role in Kerogen Anhydride Decomposition
Energy & Fuels, 2006By treatment with CrCl2, the radical populations of Kimmeridge and Bakken kerogens were significantly decreased. When both kerogens are mildly heated, anhydride formation at low temperatures can be detected by infrared spectroscopy only when radicals have been removed by CrCl2 treatment.

Kerogen Chemistry 4. Thermal Decarboxylation of Kerogens
Energy & Fuels, 2005Infrared spectra confirm that, when heated to 200 °C, Bakken kerogens form anhydrides from carboxylic acids. The anhydrides in turn thermally decompose at temperatures below 250 °C. The thermal production of CO, the absence of CO2, and the low temperature of the anhydride decomposition are all consistent with a radical chain mechanism initiated by a ...

Kerogen‐bound and free hopanoic acids in the messel oil shale kerogen
Chirality, 2001AbstractThe distribution of the free and bound hopanoic acids in both unheated and heated (350°C for 50 h) kerogens, isolated from the Messel oil shale, were analyzed by GC‐MS. The bound acids were released by subjecting the kerogen to three different treatments, namely, thermochemolysis in the presence of tetramethylammonium hydroxide (TMAH), as well ...

Relationship of Kerogen and Sporopollenin–A Reply
Nature, 1970OUR suggestion1 that kerogen present in relatively unmetamorphosed Pre-Cambrian sediments was composed of sporopollenin was initiated by our analyses and the observations of others that the organic chemistry of such sediments appears relatively constant.
