Adsorptive removal of nitrogen-containing compounds from fuel over hierarchical porous aluminosilicates synthesized by kinetic regulation method

Performance Evaluation of Synthetic Goethite and Lepidocrocite Nanoadsorbents for the Removal of Aniline from a Model Liquid Fuel through Kinetic and Equilibrium Studies

“…18,41 The Redlich−Peterson isotherm is a three-parameter hybrid isotherm incorporating both Langmuir and Freundlich isotherms. Equation 10 defines the Redlich−Peterson isotherm (10) where A (L•g −1 ) and B (L•mg −1 ) are the Redlich−Peterson constants and 'g' is the Redlich−Peterson isotherm exponent. 32 The Khan isotherm is a generalized model that is suitable for pure solutions.…”

“…The adsorptive denitrogenation method (ADN), which belongs to the non-hydrogenation category, can be a promising method due to its undeniable advantages such as selectivity, high efficiency, and flexibility. ,,,,− In this regard, finding an appropriate adsorbent with high adsorption capacity for NCCs to improve the ADN process is a necessity. − Although a wide range of adsorbents such as zeolites, silica gel, aluminosilicates, activated carbon, ion-exchanged polymers, and metal–organic frameworks had been reported, ,,− efforts are still devoted to developing new adsorbents with desirable operational, economic, and environmental characteristics. Also, the chemical structure and physical characteristics of the target impurity are of decisive importance for selecting the proper adsorbent …”

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

“…The crucial part of the process is the kind of adsorbent material employed because the adsorption of the sulfur and nitrogenous molecules would depend on the physicochemical and textural properties of the adsorbent [6][7][8]. Zeolites [5,[9][10][11][12][13], activated carbons [14][15][16][17][18][19][20], activated alumina, metal oxides, and mixed oxide [8,[21][22][23][24][25] are the most common adsorbents. Although the choice of these materials should be made considering adsorption capacity, selectivity, regenerability, lifetime, and price, some properties must be considered.…”

“…One possibility to remove sulfur compounds of larger sizes, as described above, is employing mesoporous silica materials with pores size larger than 3 nm and surfaces areas nearby to 1000 m 2 /g [23][24][25][26]. Recently, our group proved several kinds of mesoporous materials such as SBA-15, SBA-16, and MCM-41 as adsorbents of Q and DBT as model molecules representatives from diesel mixtures at 318 K and atmospheric pressure in a batch system and using different molecules [27,28].…”
