초록 ▼

Regenerative adsorption of mercury on activated carbons derived from scrap tires enables the removal and recovery of mercury from combustion/incineration flue gas, with concurrent control of SO.sub.2 and NO.sub.x. Flue gas is used for regeneration of the activated carbon, and mercury stripped from t

대표청구항 ▼

[ Having thus described the invention, what is claimed is:] [1.] A process for the recovery of mercury from a gaseous mixture, comprising the steps:(a) providing a carbonaceous feedstock having a substantial inherent sulfur content;(b) effecting pyrolysis and activation of said carbonaceous feedstock so as to produce an activated carbon sorbent having a sulfur content of at least about 3 percent by weight;(c) passing a first stream of an impure gaseous mixture containing mercury through said sorbent, at a temperature in the range of about 50.degree. C. to about 200.degree. C., so as to effect adsorption of mercury by said sorbent from said first stream, and thereby to produce therefrom a mercury-bearing sorbent and a stripped gas stream, respectively; and(d) passing a second stream of an impure gaseous mixture, as a regenerating gas stream, through said mercury-bearing sorbent at a temperature which is in the range of about 150.degree. C. to about 800.degree. C. and which is also above the temperature at which said first stream passes through said sorbent, so as to produce therefrom a mercury-rich gas stream and a regenerated sorbent, respectively.
