Abstract
A carbon-based, adsorption powder containing an effective amount of cupric chloride suitable for removing mercury from a high temperature, high moisture gas stream, wherein the effective amount of cupric chloride ranges from about 1 to about 45 wt percent. Additional additives, such as potassium permanganate, calcium hydroxide, potassium iodide and sulfur, may be added to the powder to enhance the removal of mercury from the gas stream.
