Abstract
Abstract The aim of this study is to prepare activated carbon from waste materials characterized by their environmental hazardous and polluted effect; those are spent lubricant oil (SLO) and Mishraq blow down (Mbd) the side product from Mishraq Sulfur Company. Those two materials were chosen as starting materials for activated carbon preparation. The laboratory work include the preparation of the activated carbon via two treatments, the first includes thermal treatment of (SLO) that was already oxidized under certain experimental conditions with certain percentages of (Mbd). Sample mixtures were heated at 170oC for different time intervals using 1% (wt/wt) anhydrous aluminum chloride as catalyst. The second treatment includes thermal treatment of oxidized (SLO) with different percentages of (Mbd), the mixtures were heated at 300oC for certain time intervals under additionally air stream oxidation condition. Products possessing highest asphaltene contents were chosen as starting matters for activated carbon preparation. They were simply and vacuum distilled respectively. The remained heavy material was treated with potassium hydroxide in (1:2) at 550±50oC for 3hrs. The prepared carbonaceous product was then purified and its activity was determined by adsorption ability, ash content, bulk density and humidity content.
