"The objective of this thesis is an investigation of influence of porosity, surface chemistry, material composition and effects of metals oncarbon adsorbents in desulfurization of liquid fuels. Materials are derived from poly (4-styrenesulfonic acid-co-maleic acid) salts (sodium or transition metals). They are investigated in a dynamic breakthrough process using model diesel fuel containing dibenzothiophene (DBT) and 4, 6-dimethyldibenzothiophene (DMDBT). The performance of adsorbents is evaluated in terms of the capacity and selectivity. Differences in performance are investigated considering the porosity, surface chemistry and the type of material used."
