Provided are: a formic acid decomposition apparatus which can dispose of formic acid safely and quickly and determine the activity of a packed catalyst; and a formic acid decomposition method. This formic acid decomposition apparatus is to be used in decomposing formic acid contained in an exhaust gas into water and carbon dioxide, said exhaust gas being discharged from a soldering device in which the reduction treatment of surface oxide film with formic acid has been conducted. The formic acid decomposition apparatus is provided with: a formic acid decomposition unit in which a formic acid decomposition catalyst is packed; a gas introduction pipe for introducing a formic acid-containing gas into the formic acid decomposition unit; and a gas introduction mechanism for introducing oxygen or an oxygen-containing gas into the formic acid decomposition unit. In the formic acid decomposition apparatus, the activity of the catalyst is determined on the basis of catalyst temperature change due to the heat generated in the decomposition reaction of formic acid. This formic acid decomposition method comprises: mixing oxygen or an oxygen-containing gas with a formic acid-containing exhaust gas discharged from a soldering device, in which the reduction treatment of surface oxide film with formic acid has been conducted, at a molar ratio of oxygen to formic acid (oxygen/formic acid) of 1.5 or more; subjecting the mixture to reaction in the presence of a formic acid decomposition catalyst; and thus decomposing the formic acid into water and carbon dioxide. |
