“…The Brönsted acid sites play an important role in the removal of thiophene from model gasoline-containing olefin (Li et al 2017). Among metal ion-exchanged Y zeolites, the CeY zeolite has been greatly studied owing to its high adsorption selectivity to sulfur compounds when aromatics exist (Velu et al 2003;Subhan et al 2018a). Unfortunately, the application of rare earth metal-exchanged zeolites is limited because of their low ADS capacities (Wang et al 2009;Qin et al 2014a, b).…”

A bimetal-exchanged NaY zeolite (Cu(I)-Y(III)-Y) with a desirable adsorptive desulfurization (ADS) performance was prepared and characterized by means of X-ray diffraction, specific surface area measurements, X-ray fluorescence spectrometer, X-ray photoelectron spectroscopy, thermal gravity analysis and Fourier transform infrared spectroscopy. The effect of Y(III) ions on ADS in the presence of the xylenes was investigated. Results indicated that the ADS performance of Y(III)-Y is higher than that of most reported CeY. The Y(III)-based Cu(I)-Y(III)-Y demonstrated the higher breakthrough loading than those of reported Ce(III)/Ce(IV)-based transition metal Y zeolites, showing that Y(III) ions play a promoting role in improving the ADS selectivity. For Cu(I)-Y(III)-Y, a new strong S-M interaction (S stands for sulfur, while M stands for metal) active site was formed, which might be caused by the synergistic effect between Cu(I) and Y(III). The Cu(I)-Y(III)-Y, which combined the advantages of Cu(I)-Y and Y(III)-Y, is a kind of promising adsorbent. The breakthrough loading decreased in the order of Cu(I)-Y(III)-Y > Y(III)-Y > Cu(I)-Y, and the effect of xylene isomers on the sulfur removal was in the order of ortho-xylene > meta-xylene > para-xylene, which exhibited the same trend with the bond order of xylenes.

“…As a rousingly competitive desulfurization technology, adsorptive desulfurization (ADS) has attracted signicant attention from academics and enterprises. [13][14][15][16][17][18][19][20] Various desulfurization adsorbents, for instance, metal-organic frameworks (MOFs), 21 zeolites, 22 and activated carbons (ACs), 23 have been constantly developed to fulll the requirements of desulfurization. AC adsorbents (ACA) have the qualities of simple preparation processes, low-cost, relatively high adsorption capability, and earth-abundant sources for manufacture.…”

“…Studies in this field are driven by strict environmental regulations combined with the search for new clean sources of energy such as fuel cells, where sulfur species poison the reforming catalysts and electrode materials, thus causing a shortening of the lifetime of the fuel cell and an increase in the costs of energy. [2][3][4][5][6][7][8] Hydrogen sulfide (H 2 S) is a very toxic air pollution gas owing to corrosive and flammable characteristics. H 2 S is heavier than air, and then it has a high tendency to settle in low-lying and poorly ventilated areas.…”

“…The currently important aspect of environmental policy is the removal of sulfur‐containing species from the gaseous phase. Studies in this field are driven by strict environmental regulations combined with the search for new clean sources of energy such as fuel cells, where sulfur species poison the reforming catalysts and electrode materials, thus causing a shortening of the lifetime of the fuel cell and an increase in the costs of energy [2–8] .

In this research, hybrids of N-doped carbon nanotube (NCNT)based metal-organic framework (MOF) (NCNT/UiO-66 and NCNT/ZIF-67) were synthesized using hydrothermal method. The performance of synthesized hybrids was evaluated in hydrogen sulfide removal under a dynamic system at 30-50°C with 4500 ppm H 2 S concentration as inlet feed compared with neat UiO-66 and ZIF-67. NCNT/UiO-66 and NCNT/ZIF-67 were characterized using XRD, FTIR, FESEM, BET, and TGA. NCNT/ZIF-67 and NCNT/UiO-66 showed good adsorption capability for H 2 S with a capacity of 189.72 mg/g and 175.77 mg/g, respectively. The surface area of UiO-66 and ZIF-67 is (1351 and 1290 m 2 /g, respectively), and the addition of NCNT leads to the reduced surface area of nano adsorbent hybrids. Also, the performance of hybrids would not change after three cycles of the desulfurization process. These hybrids indicated the excellent potential for a desulfurization process.
