On the mechanism of kerogen pyrolysis

Fuel, 1984
Abstract Aromaticities determined by 13 C n.m.r. are reported for five shale oil samples (Green River formation) prepared under widely different pyrolysis conditions. In the absence of high-pressure hydrogen, the total amount of aromatic carbon in the products is nearly twice that in the raw shale.

A reappraisal of kerogen formation

Geochimica et Cosmochimica Acta, 1989
Abstract Comparative microscopical and chemical studies of recognizable entities in kerogen and their extant counterparts suggest a new and simple mechanism of kerogen formation which clarifies the interrelationships between extant biomass, kerogen, and fossil fuels.

Kerogen: Composition and Classification

1978
The term kerogen will be used here to designate the organic constituent of the sedimentary rocks that is neither soluble in aqueous alkaline solvents nor in the common organic solvents. This is the most frequent acceptance of the term kerogen, and results from a direct generalization to other rock types of the definition by Breger (1961) in ...

Palynological Kerogen Classification

1995
Viewed as a whole, the published palynological organic matter classifications are characterized by a great deal of duplication of effort that has resulted in much superfluous jargon. A generally acceptable terminology has proved elusive and so workers have continued to propose new terms to describe what are, by and large, a relatively familiar set of ...
