This study reports the technical characteristics, the organic elemental composition of coal, and the inorganic elemental composition of coal ashes from four selected coals including Tavan tolgoi, Nariin sukhait, Baganuur and Shivee-Ovoo deposits in Mongolia. The thermal stability analyses of the organic mass in coal samples were also conducted with thermogravimetric analysis and discussed with the detailed mechanisms of the thermal decomposition of the coal organic mass. Furthermore, the coal samples were processed by pyrolysis at different heating temperatures and determined the yields of pyrolysis products such as hard residue, condensed liquid (tar and pyrolysis water), and uncondensed gas products. The coal ashes from the selected coals were also studied in detail and report that the ashes of high-rank coals of Tavan tolgoi and Nariin sukhait deposits have acidic character and ashes of low-rank coals of Baganuur and Shivee-Ovoo deposits have alkaline character. In addition, the coals samples from Tavan tolgoi, Nariin sukhait, Shivee-Ovoo, and Baganuur deposits were processed by pyrolysis at different heating temperatures and determined with the yields of pyrolysis products such as hard residue, condensed liquid (tar and pyrolysis water), and uncondensed gas products. The yields of hard residue from high-rank coals of Tavan tolgoi and Nariin sukhait were higher than that of low-rank coals of Baganuur and Shivee-Ovoo coal. The dewatered tar products of pyrolysis were investigated for chemical composition analysis.

In oil recovery technique using SiO2 nanoparticles, evaluating the transportability of the nanoparticles in various sandstones contributes to controls of fluid behaviour in petroleum reservoirs and improvement of oil recovery factor. In the core flooding test with high-content kaolinite sandstones, the maximum oil recovery of about 4.5% was obtained by injecting negatively surface charged nanoparticles without adsorption of a large amount of the SiO2 nanoparticles on the rocks and the pore channels plugging effect. The main mechanisms of the oil recovery were suggested wettability alteration changing to more water-wet on the rock surface and increase of disjoining

Determining vertical variation of water quality parameters is contributed to a better understanding of the true nature of lakes. Lakes are classified into holomictic and meromictic lakes by their mixing mode; the former occurs physicochemical mixing between the surface and deep waters, while the latter layers of lake water occur unmixed for years, decades, or centuries. Lake Oigon is the only Meromictic Lake identified in Mongolia. Few Mongolian lakes have been studied in different seasons but not in the vertical directions. Therefore, we studied the vertical profile of water and sediment parameters in Lake Oigon for two years. Physico-chemical parameters in water were measured on-site, while sediment parameters were determined off-site. Salinity in lake water ranged from 21.3 to 65.9 g/L which represented mesosaline to hypersaline. In oxic, sub-oxic, and anoxic zones, the physico-chemical parameters of Lake Oigon were varied a lot in longitudinal ways lake and seasonal variation observed as well. However, most parameters were stable in the anoxic zone, regardless of seasons, indicating that no water movement was at the bottom of the lake. Layered sediments with salt indicating hardly exchange with lake water at the anoxic zone. The statistical correlation and principal component analysis between the various physico-chemical parameters of lake water and lake sediment were computed. This study provides the basic information for future research on the characteristic of the vertical profile, impact on the ecosystem, and environmental assessment for Lake Oigon.

The purpose of the study was to determine chemical and organic matter compositions of peloid from Lake Khyargas in Uvs province by chemical and instrumental methods, including X-ray, ICP–OES, and GS/MS. Based on our results, it was identified that the peloid from Lake Khyargas belongs to hydrogen sulfide mud. The content of microelements ranged from 0.5–480 ppm. The peloid contains humic substance 18.08%, lipid 6.56%, and carbohydrate 15.95% in total organic matter (TOM). In addition, organic matter extracted by non-polar and polar solvents counts for 1.83% of TOM. The organic extracts were analyzed by gas chromatography-mass spectrometry (GC/MS) and identified 110 organic compounds in peloid from Lake Khyargas. There were compounds hydrocarbons and their derivatives (16.27%), carboxylic acid (12.94%), dialkyl phthalate (6.52%), element sulfur (4.53%), alcohol (17.65%), halogen bearing hydrocarbons (2.26%), nitrogen-containing compound (12.19%), cyclic hydrocarbons (0.41%), steroids (0.49%), and ketone (14.52%).

The gas-based direct reduction of iron concentrate pellets was carried out by using the typical carbon monoxide. The investigation on the influences of time and temperature of the reduction were studied. The results showed that the temperature and time of the reduction were directly related to the reduced iron content. In order to perform the iron reduction experiment, the powder iron concentrate needed to be pelletized, and the binder agents have used molasses and bentonite. As the result of the reducing experiment at the 1050°C temperature and for 120 minutes, the reduced iron content was 85.6%, and hardness was 115.5 HV which meets the requirements of the reduced iron standard.

Chlorophylls (Chls), the green pigments responsible for photosynthesis in plants, algae and bacteria, are also part of the daily diet of herbivorous feeders. Chl degradation occurs during leaf senescence and fruit ripening but is also noticed as a response to biotic and abiotic stresses. Besides the programmed degradation during senescence different factors such as high temperature, extreme pH values, enzymatic actions, molecular oxygen, and light initiate the degradation of Chl. To gain more information on Chl degradation in the gut of plant-feeding insects, regurgitate and frass of Spodoptera littoralis caterpillars were analysed for late Chl catabolites by using LC-MS, UV, Fluorescence and NMR spectroscopy. The major metabolites were determined in fresh leaves of the food plant lima bean (Phaseoluslunatus), and were compared with digestive products. The observed spectrum of metabolites can be attributed to the combined action of esterolytic gut enzymes and the strongly alkaline milieu in the digestive tract. Interestingly, linear Chl catabolites were not detected in the gut of the larvae of S. littoralis. Substantial amounts of Chl catabolites were found to be macrocyclic rings opened in the senescent food plants, but also in the aged frass. We studied two primary fluorescent chlorophyll catabolites in senescent leaves of lima bean. One of the primary fluorescent chlorophyll catabolites that have been found in the frass of S. littoralis might be generating opened tetrapyrroles of Chl, only after being exposed to the air and light.

The purpose of the present work was to perform a screening for SOD activity in plants traditionally used as food and medicine in Mongolia. The SOD activity was measured by their effects on pyrogallol autoxidation. In the studied plants, the SOD activity varied from 0.42±0.01 to 10.47±0.1 U/mg protein. Plants with high SOD activity can serve as a potential source of antioxidant supplements in the human diet. Research is currently ongoing.

We have defined the biochemical composition of the carcass meat of muskrat, including the content of the amino acids, lipids, and saturated and unsaturated fatty acids. The moisture, crude proteins, fatty acid, and ash were 74.6, 23.2, 1.2, and 0.92%, respectively. The average amount of calories was 478 kJ per 100 g meat. We separated 17 amino acids using reversed-phase high-performance liquid chromatography (RP-HPLC) analysis. The fat content was low in both male and female invasive muskrats. The aliphatic tails of the fatty acids range from 16 to 18 carbons. The saturated palmitic (C16:0) and stearic acids (C18:0), and unsaturated oleic (C18:1) and linoleic (C18:2), and linolenic acids (C18:3) were extracted. Even though some of the western provinces in Mongolia applied the carcass meat of the muskrats for treatment against kidney disease in traditional medicine, the scientific proof is still unclear.
