Abstract
The adsorption of sulfur compounds form commercial diesel oil on a granular activated charcoal (GAC) was investigated. The equilibrium of sulfur adsorption on GAC was examined. The adsorption isotherms were determined and correlated with two well-known isotherm equations: Langmuir and Freundlich. The surface chemistry and structure of the sorbent material was
studied using nitrogen sorption isotherm and scanning electron microscopy (SEM) integrated with energy dispersive spectroscopy (EDS). The sulfur and other metal contents in diesel oil were evaluated using X-ray fluorescence analyzer. Results showed that the sulfur content was reduced by 20.9 % compared to the original sample. The metal content of the sorbent materials, before and after desulfurization process, was determined using microwave acid digestion system followed by inductively coupled plasma (ICP) technique.
