Herein are disclosed compositions of matter, processes of manufacture and processes of use of solid state admixtures that include an inorganic base and a sulfide selected from the group consisting of an ammonium sulfide, an alkali metal sulfide, an alkali-earth metal sulfide, transition metal sulfide, and a mixture thereof. The composition can include solid state inorganic bases (e.g., calcium hydroxide and sodium sesquicarbonate) and/or gaseous bases (e.g., ammonia) and, optionally, a support material for one or more of the inorganic base and sulfide. The compositions are useful for capturing environmental contaminants, for example, from the flue gas of a coal fired power plant. |
