Effect of Carbon Pretreatment on Cerium Loaded Activated Carbon as Desulfurization Adsorbents

Abstract:

Activated carbon (AC) was pretreated by H₂O₂ or HNO₃ and then loaded with cerium to obtain Ce/AC composites as desulfurization adsorbents. The adsorption isotherms of as-prepared Ce/AC composites for dibenzothiophene were measured in static batch desulfurization of model fuel and compared with the one prepared without AC pretreatment. It was found that both H2O2 and HNO3 pretreatment could enhance the adsorption capacity of Ce/AC composites. The results were discussed in terms of surface chemistry and texture property. The improvement could be related to increased surface acidic groups and better dispersion of loaded metal species bought about by the two pretreatment methods
