Sodium on the Surface of Activated Carbons as a Factor Enhancing Reactive Adsorption of Dibenzothiophene
On the basis of the results described in the literature on the reactivity of sodium toward DBT and its derivates, the effect of sodium dispersed on the surface of a carbonaceous support on the removal of DBT from hexane solution at ambient conditions has been investigated. Since the main objective of this paper is to demonstrate the effect of sodium on the reactive adsorption of DBT from an organic solvent, hexane was chosen as a model solvent. As adsorbents, two carbons with and without sodium on the surface were investigated. The carbons are obtained by carbonization of polystyrene−sulfonic acid−co-maleic acid in sodium salt at 800 °C in nitrogen. The results show that sodium present on the surface of carbon takes part in the reaction with DBT in which sodium metalates and sodium sulfides are formed.
