Present paper discusses mercury control technology, beginning with a review of data on mercury removal in conventional pollution control equipment. Finally, the paper explains new technologies being developed worldwide at the pilot-scale specifically designed for gas-phase mercury removal. To develop carbon-based sorbents to be used in gas-phase mercury removal, the performance of virgin activated carbons (AC) and with that of chemically treated activated carbons was compared. Virgin AC with increased oxygen functional groups was superior in mercury adsorption performance. Pre-oxidation of activated carbons with acids were also investigated and compared with adsorption performance. The results of activated carbon injection will be introduced and the influential factors such as temperature, carbon dose (C/Hg ratio), and size effects will be discussed.
