Abstract

Abstract

Different activated carbon (AC) exhibits significant differences in the adsorption and removal of different pollutants. This article comprehensively evaluated the performance of commercial AC in the adsorption and removal of typical gasoline vapor m-xylene, and systematically investigated their adsorption performance. Selecting six ACs with different matrix materials as the research object, the static adsorption experiments were designed and by combining the characterization of physical and chemical properties of activated carbon, the AC with the best adsorption performance was used in dynamic adsorption studies, to explore the influence of gas flow rate, inlet concentration, and bed height on the adsorption performance. The results showed that the specific surface areas of the six ACs were from 851 m²/g to 1851 m²/g, pore volumes were spanning 0.047 m³/g to 0.698 m³/g, average pore sizes were between 3.0 nm and 4.3 nm, and the static adsorption capacities for m-xylene were ranging from 253.5 mg/g to 870.7 mg/g. AC-6 with a micro-mesoporous structure demonstrated the highest static adsorption capacity for m-xylene. It boasted a maximum specific surface area of 1851 m²/g, a pore volume of 0.698 m³/g, and an average pore size of 4.3 nm. Furthermore, AC-6 featured a rich array of surface functional groups, including hydroxyl, carboxyl, and ester groups. In dynamic adsorption experiments with AC-6, increasing the bed height from 0.6 cm to 1.0 cm resulted in a rise in saturated adsorption capacity from 436.6 mg/g to 465.4 mg/g. Increasing the gas flow rate, the saturated adsorption capacity was reduced from 473.1 mg/g to 430.9 mg/g; and increasing the inlet concentration, the saturated adsorption capacity was reduced from 468.0 mg/g to 386.7 mg/g, indicating that the import concentration of m-xylene had a significant impact on the adsorption performance. The adsorption kinetics of AC-6 on m-xylene complied with the Pseudo-first-order kinetic model, and the Langmuir adsorption isotherm model could better describe the adsorption process of AC on m-xylene.
