Adsorption of mercury from simulated flue gas using activated carbon produced from oil palm empty fruit bunch / Noor Hidayu Abdul Rani

Mercury pollution is a global crisis facing society today because it is a toxic and hazardous element that can severely threaten human health and environment.Activated carbon as an effective adsorbent in capturing elemental mercury from flue gas was used for this research. In this research, activate...

In this research, activated carbon was produced from oil palm empty fruit bunch (EFB) using physical (steam) activation method and response surface methodology (RSM) is applied in order to maximize the BET surfacearea.

When the inlet mercury concentration was increased, the mercury removal efficiency was increased.
