Beneficiation of Green River Oil Shale by Pelletization

Extraction of kerogen from oil shale with supercritical carbon dioxide: Molecular dynamics simulations

“…The traditional experimental approaches to extract kerogen from oil shale include differential wettability, sink-float separations, chemical methods and pyrolysis [1,[4][5][6][7][8]. Differential wettability methods are based on the principle of differential wetting of kerogen and minerals.…”

Three-Dimensional Structure of the Siskin Green River Oil Shale Kerogen Model: A Comparison between Calculated and Observed Properties

“…Source rocks in the Green River formation, one of the most extensive oil shale reserves in the world, contains hydrogen-rich algal kerogen (type I) with up to ∼20 wt % organic matter in the form of amorphous kerogen solid integrated in a silicate- and carbonate-based mineral matrix. , In the past few years, investigators have employed different methods to separate organic kerogen from inorganic minerals in oil shales and to recover the unaltered kerogen for characterization studies. − Although considerable progress has been achieved from these studies, the complete isolation of kerogen from oil shales remain difficult.…”

Review of needs for thermophysical property data on solid feedstocks II. Oil shale

“…Earlier benef iciation studies reported have been for Green River shale [111][112][113][114]. This is probably a consequence of the common use of these procedures to improve the oil yield in the Fisher assay; Fisher assay procedures are applied most successfully to Green River shales.…”

“…Reisberg [114] used the tendency of some organic liquids to be imbibed and swell the shales to induce the formation of pellets of organic phase before separating the phases.…”
