| Abstract This research work was aimed to prepare active carbon from residual petroleum refining product obtained from northern Iraqi refinery in Beji . The process involve atmospheric oxidation through air blowing with constant flow rate for 48 hrs. at 350˚C . The oxidized asphalt was grafted with different percentages of authentic lignin. The grafting process was carried out in the presence of limited amount of potassium hydroxide at a temperature of 350-400˚C for 3 hrs. and till no more physical change in the nature of mixture was observed . Furthermore, Carbonization of the grafted asphalt was carried out in the presence of twice the original weight of potassium hydroxide . The process was carried out at 400-500˚C , till no more evolution of gases or vapor was observed. Carbonaceous materials obtained through the process were purified by washing with distilled water till the water eluate is neutral . Activation of the carbon was carried out by refluxing with 30% HCl , washed with water and dried in the oven . Evaluation of the active carbon was carried out through measuring its ability in the removing of iodine and methylene blue from their aqueous solution. | ||
