Abstract:

The thermodynamics and dynamics of 1,2-dichlorobenzene adsorption on adsorbent N were investigated via the static adsorption experiments. The experimental results demonstrated that the adsorption isotherm of 1,2-dichlorobenzene adsorption on adsorbent N was S type, and Freundlich adsorption equation could describe the adsorption process well. The thermodynamic parameters illustrated that the adsorption was a spontaneous and exothermic process, belonging to physical adsorption. The adsorption dynamics appeared to be pseudo-second order equation. As adsorption temperature increased, adsorption rate constant and initial adsorption rate tended to increase. Based on the above-mentioned results, some guidance may be provided for the adsorption removal of organic chlorides from naphtha.
