Abstract

Compositions, and processes utilizing such compositions, are provided for reducing mercury emissions from combustion gases. Such compositions comprise a wood-derived or coconut shell-derived activated carbon and/or a bromide-containing inorganic salt such as an ammonium bromide or calcium bromide salt.

Claims (3)

1. A process consisting of:

combining components consisting of an ammonium bromide or calcium bromide salt and a wood-derived or coconut shell-derived activated carbon at a temperature less than 150 deg C, and

producing a composition suitable for reducing mercury emissions from a combustion gas stream, wherein the composition has a PIO that is at least about 50 deg C higher than the PIO of the activated carbon alone.
