The Chelyabinsk meteorite sample of type LL5 was subjected to calcination in the specially constructed instrument in the temperature range 200–800°C in increments of 100°C. The composition of the obtained volatile constituents was examined on a chromatograph. Detected were: CO₂, H₂O, and N₂ in concentrations of 5–40 μg/g of the sample; H₂, CO, CH₄, and H₂S in concentrations of 0.1–2.0 μg/g. By observing changes in the selected component concentrations over time (up to 90 minutes), it was concluded that chemical reactions in the system between volatile components occur directly during outgassing.

An Experimental Study of the Oil Production from Domanik Formation Rocks Under Hydrothermal Conditions     

A. V. Stennikov  I. A. Bugaev  A. G. Kalmykov  A. Yu. Bychkov  E. V. Kozlova  G. A. Kalmykov 《Moscow University Geology Bulletin》2018,73(1):60-65

The experimental results on synthetic oil production from rocks of the Domanik Formation under hydrothermal conditions are reported. The potential for oil-product extraction from the oil fractions of the rocks under a hydrothermal impact was up to 60 mg/g or 6.0 wt %. The injection of inorganic additives (sodium carbonate or silica gel) did not increase the oil-recovery factor. As well, the amount of the recoverable oil products directly depended on the mineral composition of the rocks. The relationship between the percentage of hydrocarbon yield and the mineral composition of the rocks was determined. Clay minerals and silica increased the yield of synthetic oil; carbonates, conversely, inhibit the process.  相似文献
