“…At 50 °C, the total adsorption percentages of 4,6-DMDBT and DBT were the same (42.7%), and the total nitrogen adsorption percentages of quinoline, indole, and acridine were 73.3, 52.5, and 46.7%, respectively. These results are consistent with the sulfur adsorption data in diesel oil using activated carbon at 30–50 °C . Increasing the temperature enhanced the molecular energy, resulting in an increased diffusion rate into the pores of the zeolite structure.…”

This work focused on adsorptive desulfurization (ADS) and denitrogenation (ADN) in single-and two-stage systems. Na-Y zeolite possessed the best 4,6-DMDBT and DBT adsorption performances. La-Y zeolite exhibited the best ADN efficiency. The impact of nitrogen compounds and aromatics on ADS capacity and the impact of sulfur compounds and aromatics on ADN ability over ion-exchanged Y zeolite were evaluated in the single-stage system. The nitrogen compounds not only have the ability to compete, but they also have a higher absorbability than sulfur compounds. The sequential adsorption in a two-stage system was proposed to enhance ADS ability. The first stage contained La-Y for ADN, and the second stage contained Na-Y for ADS. It was found to successfully increase the breakthrough capacity of all compounds by 40% compared with the single-stage system. This twostage sequential system is a suitable route for the elimination of sulfur and nitrogen content in diesel oil.

“…Currently, many researchers consider the adsorption method as one of the effective methods of desulphurization [15][16][17][18][19][20][21][22][23][24][25][26], which can serve as an independent method for removing SC from fuels, as well as a method for refining oil or 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; process safety (absence of high pressures and temperatures).…”

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 (C16H34S); 4,4,6-trimethyl-5-phenyl-1,3-oxazinane-2-thione (C13H17NOS); 1,2-bis(2-methylundecan-2-yl)-disulfane (C24H50S2); 3-methyl-2,4a,9,9a-tetrahydro-1H-2λ4-indeno [2,1-c]thiopyran-2-carbonitrile (C14H15NS) and 2,3,4,5-pentamethylbenzene-sulfoneamide (C11H17NO2S). 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, after which it needs restoration.

“…Due to increasingly stringent environmental regulations being imposed to reduce the sulfur content to very low levels, various deep desulfurization processes have been developed in the past few years, including adsorptive desulfurization on various substrates such as mesoporous CeMCM-41 (Ke and Xin, 2010), activated carbon (Muzic et al, 2011), nanocrystalline NaY zeolite synthesized using carbon nanotube templated growth (Tang et al, 2011), and Ni/ZnO adsorbent (Zhang et al, 2010); desulfurization based on molecular recognition (Sun et al, 2008); biodesulfurization (Bhatia and Sharma, 2006); extractive desulfurization with ionic liquids (ILs; Gao et al, 2009;Schmidt, 2008) and sulfolane (Adžamić et al, 2010); oxidative desulfurization (ODS) followed by extraction using aldehyde and molecular oxygen in the presence of cobalt catalysts (Rao et al, 2011), peroxotungstate biquaternary ammonium salt/H 2 O 2 system (Zou et al, 2011), tungstophosphoric acid in a one-step oxidation-extraction method , and phosphotungstic acid in IL .…”

The extractive desulfurization of a model and several real gasoline samples was investigated using imidazolium-based ionic liquids (ILs). Factorial design of experiments indicated that, among several process variables, the number of extraction steps and the IL/gasoline volume ratio were statistically highly significant. The results showed a desulfurization efficiency of 95.2% under the optimal conditions. The following order was observed for the extraction of thiophenic compounds: benzothiophene>thiophene>3-methylthiophene>2-methylthiophene, with 96.1% removal efficiency for the first one. The IL extraction was applied as a complementary process for the oxidative desulfurization by hydrogen peroxide and formic acid, which provided high efficiency and selectivity for desulfurization of gasoline.
