Gas condensate diesel fuels, being an excellent resource base, often do not meet modern standards of the cetane number value and the content of sulfur compounds (SC). Currently, Euro 5 and Euro 6 (<10 ppm sulfur content) diesel motor fuels are produced worldwide. High-quality diesel fuels are produced using hydro desulfurization process. Analysis of scientific publications has shown that the adsorption is effective method of desulphurization, which can serve as a method of removing SC from fuels or refining oil and its fractions, which allows removing residual sulfur. The advantages of the adsorption method are: low level of capital costs; simplicity of equipment; carrying out the process under much milder conditions compared to hydro desulfurization. In this paper, an original adsorption-catalytic method of reducing the concentration of SC to <10 ppm using a nanoporous adsorbent-catalyst is proposed. The structure and content of complex sulfur compounds in gas condensate fuels obtained from the raw materials of two deposits – Yamburgsky and Zapolyarny – were determined by gas chromatography–mass spectrometry. The next SC substances were found: tert -hexadecanethiol (C 16 H 34 S); 4,4,6-trimethyl-5-phenyl-1,3-oxazinane-2-thione (C 13 H 17 NOS); 1,2-bis(2-methylundecan-2-yl)-disulfane (C 24 H 50 S 2 ); 3-methyl-2,4a,9,9a-tetrahydro-1H-2λ 4 -indeno [2,1-c]thiopyran-2-carbonitrile (C 14 H 15 NS) and 2,3,4,5-pentamethylbenzene-sulfoneamide (C 11 H 17 NO 2 S). Three-dimensional images of SC molecules and their adsorption complexes with Al-Ni-Mo-O component of a complex adsorbent-catalyst were obtained by molecular modeling. The adsorption energies of SC on the Al-Ni-Mo-O catalyst are calculated. The obtained values of the adsorption energies are in the range of −99.17 ÷−231.66 kJ/mol. As a result of the conducted research, a cartridge with selected adsorbent catalysts has been developed, which must be activated by heating in an inert medium up to 350 ° C. The average life of the cartridge is 1.5 years, ... |
