Production of activated char from Illinois coal for flue gas cleanup
- Illinois State Geological Survey, Champaign, IL (United States)
One of the unique properties of activated carbon is that it can remove nearly every impurity found in flue gas including SO{sub 2}, NO{sub x} particulates, mercury, dioxins, furans, heavy metals, volatile organic compounds, and other trace elements. No other existing sorbent has that capability. An activated carbon-based process, typically placed after the precipitator and just before the stack, can be used alone or in conjunction with other control methods to remove SO{sub 2} and NO{sub x} from flue gas. This technology has been used in Europe and Japan for cleanup of flue gas from both coal combustion and waste incineration. Currently, no U.S. utility employs a carbon-based process to clean flue gas. An ongoing research program at the Illinois State Geological Survey (ISGS) has as one of its principal objectives the development of activated char from Illinois coal suitable for cleaning flue gas. This paper summarizes some of our recent efforts to produce activated char for several flue gas cleanup applications, including coal-fired utilities, diesel engine exhaust and waste incinerators.
