The yield, properties and composition of soluble and insoluble (kerogen) of organic matter of oil shale from Uvurjargalant deposit of Mongolia have been investigated in this study. The study result shows that oil shale contains low amount of moisture and volatile products, while the ash yield is high (71.86 %) - which implies that most of the oil shale are minerals. The total amount of bitumens in the oil shale was very low (1.27 wt %), whereas kerogen content was 22.84 wt %, which is relatively high compared to oil shale from other deposits in Mongolia. Under IR spectral analysis and the ratio of hydrogen and carbon, the Uvurjargalant oil shale belongs to I type of oil shale. The thermogravimetric analysis showed that organic matter of oil shale decomposed at a temperature 300-750 ºC to produce gas and liquid products.
In this work, we studied to obtain synthetic fatty acids raw materials to produce surfactants and various detergents from paraffin. The solid paraffin extracted from the Tamsagbulag petroleum deposit was 46 mass%, distilled 350-450°C, by complexing with urea. Experimental study indicates paraffin's physicochemical characteristics from this petroleum are more suitable to use in the production of synthetic fatty acids. By solid paraffin oxidation, we obtained 33.01% of the synthetic fatty acids containing monocarboxylic acids.We suggest obtaining the synthetic fatty acid by oxidation process in normal condition from petroleum paraffin.
In this work, fatty acids, the raw materials for detergents, were obtained by the oxidation reaction of solid paraffin extracted from the Tsagaan-Els petroleum deposit of Mongolia. The oil fraction distilled from the crude oil at 350-450°C was 20.06 mass %, and the solid paraffin was extracted from the oil fraction by complexation with urea with a yield of 34.28 %. Extracted solid paraffin contained hydrocarbons of C17-C34 and was unimodal in molecular mass distribution. Optimal conditions for the oxidation reaction of solid paraffin extracted from the oil fraction were determined by mathematical modeling depending on various reaction parameters and found to be 0.6 l/min for catalyst amount and 0.1 mass % (from paraffin) for oxygen flow. The oxidation reaction of solid paraffin extracted from the Tsagaan-Els petroleum deposit resulted in a fraction of synthetic fatty acid with a yield of 44.09 mass %. Infrared spectroscopic analysis of the synthetic fatty acids revealed that oxygen-containing compounds formed from the reaction were predominantly monocarboxylic acids and GC-MS studies have shown that these fatty acids are synthetic fatty acids containing carbon atoms of C7-C26. We report that it is possible to oxidize the solid paraffin of petroleum in our country to produce synthetic fatty acids, which are widely used in detergent production. Цагаан-Элсний ордын нефтийн хатуу парафинаас нийлэг тосны хүчил гарган авах Хураангуй: Энэхүү ажлын хүрээнд Монгол орны Цагаан-Элсний ордын нефтийн хатуу парафиныг исэлдүүлэн гадаргуугийн идэвхт үйлчлэлтэй угаагч бодисын гол түүхий эд болох нийлэг тосны хүчил гарган авах судалгааг явуулсан. Судлагдаж буй нефтийн 350-450°C-д нэрэгдэх тосны фракц нь 20.06 мас.% -ийг эзлэх бөгөөд тосны фракциас карбамидаар комплекс үүсгэх замаар хатуу парафиныг 34.28 хувийн гарцтайгаар ялган авав. Хатуу парафин нь найрлагандаа С17–С34 бүхий нүүрстөрөгчийн атом агуулсан, молекул массын тархалтаараа унимодаль шинжтэй байв. Нефтийн тосны фракцаас ялгасан н-парафиныг молекул хүчилтөрөгчөөр исэлдүүлэх процессын зохимжтой горимыг янз бүрийн параметрүүдээс хамааруулан математик загварчлалын аргаар тооцоолоход катализаторын хэмжээ 0.1 мас.% (парафинд тооцсоноор), хүчилтөрөгчийн урсгалыг 0.6 л/мин гэж тодорхойлов. Уг горимын дагуу Цагаан-Элсний ордын нефтиэс ялгасан хатуу парафиныг исэлдүүлэхэд 44.09 мас.% гарцтай нийлэг тосны хүчлийн фракцийг гарган авсан. Нийлэг тосны хүчлийн нил улаан туяаны спектроскопийн шинжилгээгээр монокарбон хүчлүүд зонхилсон хүчилтөрөгч агуулсан нэгдлүүд үүсэж байгааг тогтоосон бөгөөд хийн хроматограф-масс спектрометрийн судалгаагаар эдгээр тосны хүчил нь С7-С26 бүхий нүүрстөрөгчийн атом агуулсан дээд тосны хүчлүүд болохыг тодорхойлов. Судалгааны дүнд манай орны нефтийн хатуу парафиныг исэлдүүлэн төрөл бүрийн угаагч бодисын үйлдвэрлэлд өргөнөөр хэрэглэгддэг суурь түүхий эд болох нийлэг тосны хүчлийг гарган авах боломжтой гэж дүгнэлээ.Түлхүүр үг: нийлэг тосны хүчил, парафин, нефть, катализатор, оксидат, математик загварчлал.
