Embodiment

[0048] Hereinafter, the present invention will be described in more detail by way of examples, but the present invention is not limited to the following examples, and can be appropriately modified and implemented within the scope of the gist of the preceding and following, and they are all included in the scope of the present invention. within the technical scope.

[0049] Molded body 1

[0050] After adding potassium hydroxide in a mass ratio of 3.5 times to the carbonaceous raw material (petroleum coke) and mixing, it was heated to 800° C. in a nitrogen atmosphere, and an activation treatment was performed for 2 hours. The obtained activated product was washed with warm water (60°C), acid (hydrochloric acid), and warm water (60°C) in this order to remove metal impurities to obtain activated carbon A. Polyethylene (PE, average particle diameter of 30 μm) was added so that the content was 7.4 mass % with respect to the total of 100 mass % of polyethylene and activated carbon ...

Abstract

Provided are: an activated carbon molded body which has a large pore volume and has the strength to allow a desired shape to be molded therefrom; and a method for manufacturing the same. This activated carbon molded body has a pore volume per molded body volume (cm3 / cm3) obtained from the product of the total pore volume (cm3 / g) of the activated carbon molded body and the molded body density (g / cm3) of 0.39 cm3 / cm3 or greater, and a strength of 0.1 MPa or greater.

Description

technical field [0001] The invention relates to an activated carbon shaped body, a method for preparing the activated carbon shaped body, and an adsorption material and a storage material using the activated carbon shaped body. Background technique [0002] Activated carbon is widely used as various adsorption materials due to its large specific surface area and well-developed pore structure. For example, it is used in various liquid-phase treatments such as water purification treatment and various gas-phase treatments such as deodorization treatment and air cleaning treatment. In addition, activated carbon has attracted attention due to its properties such as conductivity and electron accepting function, or the ability to highly disperse catalysts on the surface of the pores of activated carbon, so it can be used as carbon electrodes for electric double layer capacitors, fuel cells, It is used as electrode materials such as carbon electrodes for batteries such as air batte...
