The conventional technique of hydrodesulfurization (HDS) faces challenges while removing refractory sulfur compounds from liquid fuels. Alternative techniques are under exploration. One of the alternative techniques is adsorptive desulfurization (ADS). In ADS, an adsorbent is used to remove sulfur through physical or chemical adsorption. Moreover, it is possible at ambient conditions. Recent developments in the area of ADS is the focus of the present review. Various adsorbents have been assessed for ADS of the model and real feedstocks. These include both activated carbons and zeolites. Their modification through incorporation of metal ions can improve the performance. Present paper reviews recent progress regarding the development of adsorbents. Improvement of selectivity and stability along with regeneration and reuse too, reviewed. Regeneration studies are helpful in knowing the reusability of adsorbents. Various methods of regeneration such as thermal, solvent and their combination have been addressed. Thus, present paper covers modification, testing, regeneration and reuse of adsorbents for ADS of liquid fuels. Equilibrium, kinetic and thermodynamic studies relevant to chosen topic also reviewed. Challenges do exist in testing adsorbents for ADS of commercial fuels. These challenges arise due to the competitive adsorption between sulfur compounds and aromatics. For commercialization of ADS, the development of adsorbent with cheaper metal ions and ideal regeneration methods are essential.

Activated carbon (AC) was developed from pinecone using KOH as an activator to eliminate dibenzothiophene (DBT) from a synthetic model of gasoline fuel. The best sample was the AC prepared, employing a 1.5:1 KOH: feed impregnation ratio at 750°C for 1 h. Thus, it was tested in the adsorptive elimination of DBT from the fuel after being identified by X‐ray diffraction (XRD), field‐emission scanning electron microscopy (FESEM), energy dispersive X‐ray (EDX), N2 adsorption–desorption isotherms, pore volume distribution, Fourier transform infrared spectroscopy (FTIR), total basic and acid groups, and pHPZC. The as‐obtained AC exhibited a Brunauer–Emmett–Teller (BET) surface area of 478.89 m2/g with an average pore size of 2.0 nm, indicating its micropores structure. A removal performance of 97.90% was obtained using 0.30 g of AC at 20°C for 30 min, while the adsorptive capacity amounted to 34.38 mg/g as per the Langmuir isotherm. The as‐synthesized AC exhibited a good adsorptive performance for eliminating S compounds from commercial gasoline (42.11%) under the optimal experimental conditions, which increased to 88.16% with increasing the mass of AC implemented in the adsorption process. The adsorption of DBT through the fixed‐bed approach was also adopted, and the results at various flow rates of the effluent through fixed bed of the AC were close to that obtained via the batch‐adsorption system. The regenerated AC exhibited excellent adsorptive performance for DBT until 5 cycles of reuse, reflecting the effectiveness of the obtained AC. Finally, the Langmuir adsorption isotherm and pseudo‐second‐order kinetics model best described the DBT adsorption by the AC developed from pinecone.

Thermal pyrolysis of mixed date stones and pistachio shells in a semi‐batch reactor was addressed in this study. The highest yield of liquids (51.20 %) was produced at 500 °C, 90 min, 20 °C/min heating rate, and 50 mesh particle size. Under these conditions, yield of liquid from date stones and pistachio shells separately was 49.12 % and 47.67 %, respectively. The FT‐IR results confirmed the presence of multiple oxygen‐containing compounds in the bio‐oil. Results from GC–MS declared that it was predominately composed of acids (57.57 %), esters (21.35 %), phenols (4.63 5), and alcohols (3.49 5). The obtained biochar was transformed into activated carbon (AC) by the optimized ZnCl2 activation method. The ideal AC was synthesized at 600 °C for 60 min using a 2 : 1 ZnCl2: biochar impregnation ratio. FESEM and XRD measurements showed that the AC was amorphous. The prepared AC was effective in eliminating dibenzothiophene (DBT) from model fuel (200 ppm DBT/hexane) with a maximum performance 95.26 % at 40 °C for 1h using 0.35 g of the AC. The exhausted AC was regenerated and reutilized 4 times, and removal efficiency reached 88.23 % in the 4th cycle under ideal working conditions.
