Reuse and activation of petroleum coke to remove metals in water

In the investigation I am reused the coke generated in the refinancing of the petroleum. It was proposed to activate al coke with characteristics of a carbon activated commercial and subsequently to use it to remove silver and present mercury in water. The carbon activated produced and the carbon activated commercial, LQ1000, they were characterized with the norms ASTM, indicate of iodine, area superficial al blue of methylene and indicate of blue of methylene and the results were compared. Likewise in the process of adsorption, the process of adsorption itself model with the equations of Freundlich and Langmuir. The activation of the coke I am planned through a design of experiments four factorial. The 16 coals produced were submitted al process of adsorption silver and mercury by duplicate. The study I report al coke activated as better adsorbent than the LQ1000 and with a smaller cost of fabrication but with a smaller one area superficial that the commercial one. The results obtained permit to produce carbon activated from the coke but economic to compete with the commercial coals activate
