Abstract
Description
【発明の詳細な説明】 本発明は、ガス中の水銀蒸気吸着剤に関する。[Detailed description of the invention] The present invention relates to mercury vapor adsorbents in gases.
電解水素ガス、天然ガス、焼却炉排ガス、水銀を取扱う
工場の排ガス中には、水銀蒸気が含まれていることが多
い。Mercury vapor is often contained in electrolyzed hydrogen gas, natural gas, incinerator exhaust gas, and exhaust gas from factories that handle mercury.

因となる。また焼却炉排ガスおよび水銀蒸気を取扱う工
場の排ガス中の水銀蒸気は、大気汚染上または作業環境
上、問題となる。Electrolyzed hydrogen is used in the process of manufacturing pharmaceuticals, foods, and other products, and this can pose problems because trace amounts of mercury vapor can poison the catalyst or get mixed into the products. Mercury vapor in natural gas corrodes aluminum heat exchangers during the gas liquefaction process, causing major accidents. Furthermore, mercury vapor in incinerator exhaust gas and exhaust gas from factories that handle mercury vapor poses problems in terms of air pollution and the working environment.
したがってこれらガス中の水銀蒸気は、何らかの処理に

乾式吸着法では、水銀蒸気の吸着容量が小さく充分満足
し得るものではない。Therefore, mercury vapor in these gases must be removed by some kind of treatment. Until now, known methods for removing mercury from gas include chemical cleaning methods and dry adsorption methods using adsorbents such as activated carbon and ion exchange resins. There are disadvantages such as insufficient removal efficiency and generation of waste liquid. The latter dry adsorption method has a small adsorption capacity for mercury vapor and is not fully satisfactory.

Activated carbon carrying potassium, sodium or ammonium iodide or bromide as the first component and ammonium, aluminum, vanadium, iron, cobalt, nickel, copper or zinc sulfate or nitrate as the second component is used in the gas. It was discovered that mercury vapor can be adsorbed efficiently and the amount of adsorption capacity is extremely large. It has also been found that the activity of supporting sulfur as a third component in addition to the first and second components described above further increases the removal efficiency and adsorption capacity of mercury vapor.
