Catalytic regeneration of mercury sorbents

•The regeneration of activated carbon as a mercury sorbent is investigated.•FeCl3 and NaCl are found to be suitable catalysts for HgCl2 decomposition.•Reaction rate can be increased by a factor of 10.•Activation energy can be reduced by as much as 40%. Traditionally, mercury sorbents are disposed of...
