The performance of activated carbon and carbon fiber was improved by modifying its surface property and discovered the functional groups that are effective for the adsorption using straight run gas oil. The activated carbons had larger adsorption capacity than silica gel, which was practically treated in the refinery. MAXSORB-II of largest surface area and highest oxygen content exhibited the best adsorption capacity. CO producing functional groups were responsible for adsorptive removal of nitrogen species. Thus, introduction of such group through the surface oxidation was very effective to enlarge the adsorption. Adsorption capacity of carbon materials depended on their textural and surface properties. The most important functional group of activated carbon was C=O group and carbonyl group could inhibit the nitrogen species adsorption.
