A cleaning composition for treating acid gas. The cleaning composition comprises an iron-containing oxide, and an oxide comprising at least aluminum, silicon, or titanium with a mesoporous structure. A method for treating an acid gas utilizing the cleaning composition comprising contacting an acid gas with the cleaning composition for lowering the concentration of the acid gas is also disclosed.
摘要:
A wet electrostatic precipitator is disclosed to include a condensation-growth chamber, a precipitation chamber connecting with the condensation-growth chamber, three dual-sleeve members mounted in the precipitation chamber, three discharge electrodes connecting with the dual-sleeve members, two insulating members covering on the inner surface of the precipitation chamber, and two ground electrodes mounted on the outside of the precipitation chamber. Thus, a uniform water film is formed on the surface of the insulating members to wash away the particles from waste gas. The condensation-growth chamber is provided for the particles to grow therein and thereby enhances the collection efficiency. The insulating member acts as a shield between the discharge electrodes and the ground electrodes and thereby avoids a short circuit or sparks.

The invention provides a method for decomposing sulfur-fluorine-containing compound and apparatus thereof. Sulfur-fluorine-containing compound is decomposed in two steps, comprising contacting the compound with a first catalyst such as a monometallic catalyst and a second catalyst such as a bimetallic catalyst, and at a low reaction temperature to produce resulting compounds capable of water-solubility. Then, the resulting compounds, namely sulfur- or fluorine-containing compounds, are removed by washing.
