    • To provide a method and apparatus for treating a waste gas containing fluorine-containing compounds, according to which PFCs can be decomposed efficiently even at low temperature, and moreover fluorine from the product of the decomposition can be recovered for reuse efficiently. An embodiment of the present invention relates to a method of treating a gas containing a fluorine-containing compound, comprising contacting the gas with a treatment agent comprising a mixture of aluminum hydroxide and calcium hydroxide. Moreover, another embodiment of the present invention relates to an apparatus for treating a gas containing a fluorine-containing compound, comprising a treatment column comprising a hollow interior that is packed with a treatment agent comprising a mixture of aluminum hydroxide and calcium hydroxide and through which the gas can pass, heating means capable of heating the hollow interior to a prescribed temperature, a gas introduction port for introducing the gas to be treated into the hollow interior, and an exhaust pipe for discharging gas produced from the hollow interior.
    • 为了提供一种用于处理含氟化合物废气的方法和装置,根据该方法和装置,PFCs即使在低温下也能有效地分解,而且从分解产物中还可以有效地回收氟。 本发明的一个实施方案涉及一种处理包含含氟化合物的气体的方法,包括使气体与包含氢氧化铝和氢氧化钙的混合物的处理剂接触。 此外,本发明的另一个实施方案涉及用于处理含有含氟化合物的气体的设备,其包括处理塔,该处理塔包括中空的内部,该中空内部填充有包含氢氧化铝和氢氧化钙的混合物的处理剂, 气体可以通过,能够将中空内部加热到规定温度的加热装置,用于将待处理气体引入中空内部的气体导入口,以及用于排出由中空内部产生的气体的排气管。
