Adsorption-catalytic method for reducing the content of sulphur compounds in gas condensate diesel fuel

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