Effects of oxidative modification of carbon surface on the adsorption of sulf…

Abstract. This work examines the effects of modification of activated carbons (ACs) by HNO3 oxidation and gasphase O2 oxidation, respectively, on the liquid-phase adsorption of sulfur compounds in diesel fuel. The adsorption characteristics of the oxidized and the original AC samples were evaluated in a fixed-bed flow systemby using amodel diesel fuel containing 400 parts per million byweig…
