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 solid residues. 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. [ABSTRACT FROM AUTHOR] |
