Simultaneous desulfuration and denitrogenation of model diesel fuel by Fe-Mn microwave modified activated carbon: Iron crystalline habit influence on adsorption capacity

Simultaneous adsorption of quinoline and dibenzothiophene over Ni-based mesoporous materials at different Si/Al ratio

“…8a), presenting values higher (129-259 mg/g) than Ahmed et al [47] between 110−170 mg/g. We can observe that the best fitting considering at Si/Al = 150 and ∞ ratio was when considering the Langmuir model, in the same way that Arcibar-Orozco et al [48]. Thus, assume that Q adsorbs formation of a few adsorption layers, and it can be seen that the highest nitrogen adsorption was found at Si/Al = ∞ followed by 150 ratio.…”

Deep Denitrogenation of Model Diesel Fuel Using Ni‐doped Mesoporous Carbon: Synthesis Route and Adsorption Study

“…Many approaches have been used for denitrogenation of fossil fuels such as hydrotreating, [17] adsorption, [18–21] oxidation, [22] and extraction [23] . Among all, conventional denitrogenation method in large‐scale (industry) called hydrodenitrogenation (HDN), an energy‐intensive and expensive method, performed by employing an appropriate heterogeneous catalyst (e. g., Al 2 O 3 ‐supported Mo, Ni‐based catalysts, etc.)…”

Evaluation of adsorptive desulfurization performance and economic applicability comparison of activated carbons prepared from various carbon sources

“…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.…”
