Abstract

The invention discloses a method for producing super active carbon. The method comprises the following steps of: mixing a carbon raw material and KOH and continuously introducing an inert gas into a reaction system; raising the temperature of the reaction system to 400 to 500 DEG C, adjusting reaction pressure to be 2 to 8 atmospheric pressures and continuously heating to activation temperature; cooling the reaction system to below 150 DEG C after the activation is finished, stopping introduction of the inert gas and continuously introducing air; and after the reaction system is cooled to below 100 DEG C, taking the activated material out and dissolving KOH and K2O in the activated material with water to realize recovery of KOH. The invention also discloses a device used by the productionmethod. By using the method and the device, the problem of serious production safety caused by production and releasing of monomer potassium in the process of producing the super active carbon by KOHactivation can be solved, so that industrial production of the super active carbon by applying the KOH activation method comes true.

Description

technical field

[0001] The invention belongs to the technical field of chemical production, and in particular relates to a key technology for safe production of super activated carbon produced by a KOH activation method, that is, a production method and a production device of super activated carbon. Background technique

[0002] Activated carbon is a kind of highly developed pore structure and high specific surface area (usually 800 ~ 1500m 2 / g) excellent carbonaceous adsorbent, has been widely used in many fields such as environmental protection, chemical industry, food and military industry. Super activated carbon is a kind of specific surface area greater than 2000m 2 / g of new porous carbon materials, it has broad application prospects in the fields of super electric double layer capacitor electrode materials, catalyst supports, gas separation, hydrogen and natural gas storage materials. Therefore, super activated carbon has become a new type of carbon material that h...
