Elimination of Dibenzothiophene from Model Gasoline by Binary Biowastes-Derived Activated Carbon

A novel activated carbon (AC) was created from an equal blend of date stones and walnut shells by ZnCl2 chemical activation. The impact of the impregnation and the carbonization conditions on the AC synthesis was investigated. Numerous techniques were used to identify the optimal AC. The best AC sample was created at a 1:1 ZnCl2/feed impregnation ratio, 500 degrees C, and in 60 min, with a surface area of 1039.20 m(2)g(-1). This AC was employed for the removal of dibenzothiophene (DBT) from model gasoline. Superior removal of DBT (98.18 %) was accomplished using 25 mL DBT solution (200 mg L-1) and an AC dose of 0.35 g at 30 degrees C for a contact period of 30 min. The Freundlich isotherm and the pseudo-second-order kinetic model best described the DBT sorption compared to other models.
