Method of removing mercury from exhaust gases
First Claim
1. A method of removing mercury from mercury-containing exhaust gases emanating from an industrial process or a combustion process, said method comprising:
- contacting the mercury in the exhaust gases with a sorbent material at a location where the temperature of the exhaust gases is higher than room temperature, wherein the sorbent material is hydrogen mordenite or hydrogen clinoptilolite, for adsorbing mercury and causing the mercury to react with the sorbent material to produce mercury-laden sorbent material.

Abstract
Efficient removal of mercury from the exhaust gases of an industrial process or combustion process can be achieved using an adsorbent that can be regenerated by a simple and efficient method. The mercury is contacted with a sorbent material, the sorbent material being hydrogen mordenite or hydrogen clinoptilolite, for adsorbing mercury and causing the mercury to react with the sorbent material to produce mercury-laden sorbent material. The mercury-laden sorbent material can be heated to a temperature of at least about 400° C. so as to remove mercury from the mercury-laden sorbent material and to regenerate the sorbent material to allow reusing of the sorbent material for mercury removal.
