Petroleum Coke Carbon, Characterization, and Environmental Application

Activated carbons were prepared from petroleum coke of Khartoum Refinery Company delayed coke unit (KRC-DCU) by chemical activation methods with KOH as active agent, It has been found that under the identical experimental conditions the porous carbon obtained was about 68?61% in yield, Iodine Number and Methylene Blue around 1248.1-1242 mg/g and 43- 51mg/g respectively, The results showed that the carbon obtained from coke by KOH activation in ratio 1:4-1:5 Coke: KOH and 60 min activation time is less in time and cost in comparison to the traditional methods. It also observed that the adsorption of Zn2+ on petroleum active carbon depends on the pH of solutions, contact time, and doses of adsorbent. Adsorption of Zinc+2 from water was found to fit Freundlich isotherm model with a linear curve and R ? 0.9731.
