Desulfurization of diesel fuel in a fixed bed adsorption column – process control and modeling

Adsorption was investigated as a perspective separation process for desulfurization of diesel fuel that can achieve sulfur concentrations of less then 10 mg/kg. Compared to the conventional hydrodesulfurization process, the adsorptive removal of sulfur compounds can be accomplished at relatively low temperature and pressure. In this work desulfurization of diesel fuel was carried out in a computer controlled and completely automated adsorption apparatus with fixed bed column and activated carbon SOLCARB C3 from Chemviron Carbon, Belgium, as the adsorbent. The process control software was specifically developed for the designed system using Microsoft Visual Studio package. The process of adsorptive desulfurization of diesel fuel in a fixed bed column was modeled in order to describe the kinetics and to estimate the breakthrough curves. The models ability to fit the experimental data was satisfactory.
