ABSTRACT:
Sulfur-impregnated activated carbon which has become spent by the absorption of mercury is made non hazardous for disposal purposes such as by burying. The spent carbon is at least partially combusted in a fluidized combustion zone. The solid residue is substantially reduced in mercury content. Combustion gases are cooled and condensed mercury is collected from the cooler.
