Abstract

In this work activated carbon of a good quality prepared using oxidation condensation process. The oxidation of the asphaltic materials was conducted using several percentage of NaIO4 and in the presence of a stream of air or oxygen. The reaction mixture was heated at 3 50°C for 3hrs, this followed by removal of uncarbonized materials by heating under reduced pressure. The condensation of the fractions obtained is expected to recombine or re-react to give a high carbon content. The carbonization and activation was conducted at 550±25°C for3hrs. by mixing with NaOH, and the ratio of the feedstock to NaOH (1:2). After the carbonization was completed, the reaction mixture was subjected to purification by treatment with 10% HC1 and distilled water till it gives neutral test to the litmus paper. The samples were dried at 120°C for 24hr. and its physical properties were determined. The research work indicated that a good quality activated carbon was obtained when the oxidation of sample was conducted using 3%
