“…Long-chain fatty acids with high molecular weight are used for the production of synthetic detergents. The fatty acids necessary for the production of soap are extracted from crude oil [6] or paraffin oxidation [7]. A toilet soap is produced by the neutralization of acids containing from 10 to 16 carbon atoms in the molecule yields.…”

The use of fossil fuels (methane, oil, etc.) is undergoing an unprecedented crisis now. There is the urgent need to search for alternative energy sources. A wide range of degraded organic materials can be effectively used to provide energy together with environmental protection. Soapstock is a hazardous waste containing a high concentration of toxic organic compounds of man-made origin (fatty acids, surfactants, dyes, etc.). To prevent environmental contamination such substances require an effective treatment approach. The goal of the study was to isolate the adapted-to-fatty-acids methanogenic microbiome and investigate the patterns of sodium acetate and soapstock degradation with simultaneous biomethane synthesis. The effectiveness of the degradation of sodium acetate and soapstock by non-adapted and adapted microbiomes was evaluated by decreasing the concentration of dissolved organic compounds. The effectiveness of the fermentation process was determined by the biogas (mixture of CH4 and CO2) yield. The most effective degradation occurred in the variant with sodium acetate and adapted methanogens and amounted to 77.9%. In other variants, the patterns and the efficiency of purification were similar ranging from 60.6 to 68.0%. The biomethane was mostly synthesized by adapted methanogens on the soapstock and sodium acetate as substrates. Thus, the CH4 yield was 368.4 L/kg of dissolved organic compounds or 127.5 L/kg of soapstock. The results of this study demonstrated the potential of methanogenic microorganisms in the biodegradation of soapstock with simultaneous biogas synthesis. The results can serve as a basis to reduce the reliance on fossil fuels by generating biomethane via the fermentation of toxic organics.

Cracking is the complex physical and chemical process of converting high molecular hydrocarbons into valuable products such as gasoline fraction and light fuel fraction. There are several oil fields in Mongolia and three large deposits already are being exploited. The crude oil was classified as high-paraffinic crude oil because of its high viscosity and low yield of fuel fraction. The contents of asphaltenes and resins in the oil were low. Therefore, the cracking process is necessary to convert the paraffinic Mongolian crude oil to lighter distillates for the production of transportation fuels and chemicals. In this work, we studied the hydrocracking process of atmospheric residue (>350°C) to produce fuel fractions from high paraffin Tsagaan-Els oil of Mongolia. The hydrocracking experiment was carried out with and without a catalyst at temperature 450°C for 1-3 h under a hydrogen pressure of 5 MPa. Commercial Ni-Mo/Al2O3 catalyst (Ni 3%, Mo 15%) was used in the hydrocracking experiments for 1 and 2 h. The yields of light and middle distillates obtained by hydrocracking of the atmospheric residue for 3 h without catalyst were 15.8 and 17.7 wt.%, respectively. The effect of catalyst was tested in the experiments for 2 h. By the hydrocracking with catalyst, the yield of light distillate has increased 4.5 wt.% in comparison with the yield of light distillate obtained from the experiment without catalyst. In this study, we report that the atmospheric residue in the Tsagaan-Els oil could be liquefied by thermal cracking at 350°C to increase the yield of gasoline and diesel fuel.

In this study, we have compared the physio-chemical parameters, elemental and group composition of oil and atmospheric residue from Tamsagbulag (TB) and Tsagaan Els (TsE) deposits in Mongolia, and have studied the possibility of increasing the yield of fuel fractions via thermal cracking. The atmospheric residue for oil TB is 53.8%, and for oil TsE, it's 73.63%. Both oils and their atmospheric residues are paraffinic, have medium density, and are high in saturates+aromatics but low in asphaltene-resin compounds. Atmospheric residues were loaded into a 50 ml steel reactor and subjected to a thermal cracking process at 450°C and 4 atm nitrogen pressure for 60 and 120 minutes. As a result of the thermal cracking of atmospheric residues of Tamsagabulag and Tsagaan Els, 88.6% and 56.33% of liquid products were formed, respectively, along with the formation of by-product gas and solidresidues. The liquid product from the thermal cracking Tamsagbulag atmospheric residue comprises 11.93-12.02% gasoline and 22.57-27.61% diesel, while that from the Tsagaan els consists of 13.52-18.19% gasoline and 19.47-20.69% diesel fraction. Based on the composition of the produced liquid products and chromatographic results of alkane hydrocarbons it was evident that high molecular-weight hydrocarbons and long-chain alkane hydrocarbons decompose into hydrocarbons of smaller molecular size. These results show that atmospheric residue from highly paraffinic oil can be liquefied by thermal cracking to boost the gasoline and diesel yields.
