The CO 2 concentration released by oil shale began to accelerate at 200 °C, and reached a peak value of 140,400 ppm at 510 °C. During this period, there were large concentration fluctuations, and then the CO 2 concentration decreased rapidly. Dry distillation has advanced the temperature at which the CO 2 concentration of oil shale …

The oil shale particles on the sieve surface are crushed (PEW400 × 600) and fed into the buffer bin together with the screened oil shale particles. Oil shale in the buffer bin is fed into the compound dry separator (FGX-10) via a vibrating feeder and beneficiated under certain density in the autogenous medium bed.

The USGS Energy Resources Program has studied oil shale resources of the United States, with a significant effort on the Eocene Green River Formation of Colorado, Utah, and Wyoming. This formation contains the largest oil shale deposits in the world. Oil shale, despite the name, does not actually contain oil, but is a precursor of oil that is …

Oil Shale can only be found by Mining in the Desert biome. Oil Shale is placed into your Inventory when mining Oil Deposits. It has a purple hue and is somewhat shiny on higher graphic settings, with a brushed appearance as seen here as a Surface Node. Oil Shale is found in the Desert by digging down at about 20 blocks, where the stone layer begins. It …

The crushed oil shale is mixed with the particles less than 6 mm. Then they are delivered to the surge bunker and fed to the compound dry separator. Oil shale particles are loosely stratified by the synergistic effects of vibration and airflow in the separator bed. The light oil shale particles in the upper layer are discharged from the …

The Green River Formation has economic significance, but also provides information for lacustrine source rock deposition (Hasiotis and Honey 2000; Bradley 1970; 1931).It is known that lacustrine systems are more sensitive to climate change, due to the smaller volumes of accumulated sediment and water than marine systems (Bohacs and …

In the short space of 10 years following the turn of the millennium, shale gas completely transformed the global energy market. This new natural gas resource, extracted in more than 30 sedimentary basins across the continental USA and others worldwide, accounted for about 1% of gas production in the USA in 2000, 10% in 2011, and may …

Our research group prepared a new filling paste consisting of steel slag–oil shale residue and no admixtures. It was used as the research object to explore the combined effect of chloride and dry–wet cycling-driven erosion on the long-term stability of a cemented filling paste made of total solid wastes. Macroscopic experiments and …

1. Introduction. Oil shale is a highly ash-rich sedimentary rock enriched with combustible organic matter [1], [2].The majority of the organic matter in oil shale is kerogen [3], [4], which is insoluble in common organic solvents [5], [6].The kerogen component is about 3% to 15% in oil shale, and consist of complex organic compound in high …

The technology for in-situ conversion of oil shale is based on hydraulic fracturing, whereby the fractured oil shale is subjected to heating through methods such as hot steam injection, electricity, combustion, and radiation (Liu, 2019).At elevated temperatures, the kerogen within the oil shale undergoes pyrolysis, resulting in the …

The term oil shale is often described as a misnomer, in that the organic component is primarily kerogen, not oil and the mineral matrix is not necessarily clay mineral-rich, but can include a variety of different phases (Miknis and McKay 1983).Oil shales are essentially a type of petroleum source rock, the key differences being that: (1) …
