Electron paramagnetic resonance studies of oil shale, shale oil, and spent shale
Geochimica et Cosmochimica Acta, 1979Abstract Electron paramagnetic resonance (EPR) reveals the presence of free radicals in raw shale, shale oil, and spent shale. Thirty-four samples of raw shale, and the spent shale and shale oil produced in the Fischer assay of these raw shale samples were studied.

Publisher Summary Shale oil, known also as kerogen oil or oil-shale oil, is an unconventional oil produced from oil shale by pyrolysis, hydrogenation, or thermal dissolution. The amount of shale oil that can be recovered from a given deposit depends upon many factors. Geothermal heating, or other factors, may have degraded some or all of a deposit, so

Abstract For exploring and optimizing the oil shale fluidized bed retort with fine oil-shale ash as a solid heat carrier, retorting experiments of oil shale and fine oil-shale ash mixtures were conducted in a lab-scale retorting reactor to investigate the effects of fine oil-shale ash on shale oil. Oil shale samples were obtained from Dachengzi Mine,

Q-band e.p.r. spectra of oil shale, spent shale, and shale oil
Fuel, 1981Abstract Comparison of X-band (9.1 GHz) and Q-band (35.2 GHz) electron paramagnetic resonance (e.p.r.) spectra of oil shale, shale oil, and spent shale indicates that the organic free radical signal observed in all three types of samples is a composite spectrum.

Geophysical tomographs were made of oil shale at the Occidental Oil Shale, Inc., mine near DeBeque, Colorado. These tomographs mapped the in situ radio frequency electromagnetic attenuation of oil shale between 1 and 40 MHz in a plane 27 by 12 m. Measured attenuation rates (inverse skin depth) ranged from 0.1 to 0.5 m−1 with the attenuation rate ...

It is generally agreed that the world's energy needs are now doubling every 20 years. Within 10 to 15 years, this rate of increase should create a wide enough gap between crude oil supply and demand to enable other sources of energy to enter our economy on a competitive basis.

The composition of oil shale is described. It is pointed out that although kerogen is the most common form of organic C on earth, there has been relatively little fundamental chemical research on this organic polymer. Results of chemical analyses of mineral and organic fractions of Green River oil shale are given.

The results of studies of organic matter of Mongolian oil shales are presented. The total amount of bitumens in the shales is less than 2 wt %, whereas the kerogen content is about 15 wt %. A high H/C value (1.5–2.3) and the prevalence of aliphatic over aromatic structures in the insoluble organic matter indicate the usefulness of these oil shales as ...
