Abstract

The invention discloses a 3D space net structure active carbon fiber skeleton and a preparation method thereof and belongs to the field of active carbon materials. The preparation method comprises a multidirectional-distributed interlaced crosswise-bonded integral non-woven preformed material is prepared from wood fibers and a polymer binder as carbon sources, and the preformed material is subjected to carbonization and activation to form the polymer binder active carbon-fixedly connected 3D space net structure active carbon fiber skeleton. Compared with the existing powdery or granular or active carbon fiber-woven material, the active carbon fiber skeleton has good integrity, high porosity, good adsorption capacity and good biocompatibility, is mainly prepared from reproducible plant fibers, has a low making cost and can be widely used for fields of water purification, gas purification, water ecological restoration and catalytic carriers.

Description

technical field

[0001] The invention relates to an activated carbon fiber skeleton with a three-dimensional space network structure and a preparation method thereof, belonging to the technical field of activated carbon materials. Background technique

[0002] Activated carbon is a porous material with large specific surface area, strong adsorption capacity, acid and alkali resistance, heat resistance, insoluble in water and organic solvents, and is an environmentally friendly adsorption material and catalyst carrier, widely used in chemical industry, environmental protection, food Processing, metallurgy, military chemical protection and other fields. The main forms of activated carbon products are powder, granular and columnar, generally one-dimensional or two-dimensional structure, three-dimensional structure is difficult to process, high processing cost, difficult to meet the needs of market applications.

[0003] The activated carbon with three-dimensional structure incl...
