A method for preparing a carbon material for an electrode is provided that comprises a step for activating a mixture of a carbonous main material and a conductive additive.

Method for preparing carbon material for electrode of electrochemical devices

Disclosed is an apparatus for processing an exhaust gas containing an alkaline substance, the exhaust gas being emitted when activating a carbon material with an alkaline substance. The apparatus includes a humidified-gas preparing device for preparing a humidified gas, which exhibits a dew point of 25&#xb0; C. or more; a gas mixing device for mixing the humidified gas with the exhaust gas at a temperature equal to or greater than the dewpoint of the humidified gas, thereby generating a hydroxide of metallic alkali; and a trapping device for trapping the generated hydroxide out of the mixture gas of the humidified gas and the exhaust gas.

Method of processing alkali-activation exhaust gas

Disclosed is a method for processing an exhaust gas containing an alkaline substance, the exhaust gas being emitted when activating a carbon material with an alkaline substance. The method includes the steps of preparing a humidified gas, which exhibits a dew point of 25&#xb0; C. or more, by mixing an inert gas with water vapor, generating a hydroxide of metallic alkali by mixing the humidified gas with the exhaust gas; and trapping the generated hydroxide out of the mixture gas of the humidified gas and the exhaust gas.
