Activated carbon fiber ball and preparation method thereof

Abstract

The invention discloses an activated carbon fiber ball and a preparation method thereof, and belongs to the field of activated carbon materials, and provides the activated carbon fiber ball mainly aiming at the problems that the activated carbon fiber is over-high in preparation cost, low in porosity, large in subsequent processing difficulty, single in form, inconvenient to fill and the like at present. According to the main technical scheme, the preparation method of the activated carbon fiber ball comprises the following steps: mixing short carbon fiber with a liquid-containing binder and then stirring at a high speed to form a fiber ball; adding a thermosetting resin emulsion or solution according to the solid content; secondarily rolling and cladding to prepare a fiber / resin ball; solidifying for 2-10 hours at 100-300 DEG C, so as to prepare a solidified ball; putting the solidified ball into a carbonization and activation furnace; and carbonizing and activating by water vapor, so as to prepare the activated carbon fiber ball. The activated carbon fiber ball is good in strength, good in particle sphericity, convenient to fill and exchange, good in permeability, light in weight, strong in adsorption capacity, high in sphere strength, and excellent in inoxidizability and corrosion resistance, and can be widely applied to water treatment, air purification, trace pollutant removal, a catalyst carrier and the like.

Description

technical field [0001] The invention belongs to the field of activated carbon materials, and in particular relates to an activated carbon fiber pellet and a preparation method thereof. Background technique [0002] Activated carbon particles have the advantages of convenient use, low price, developed mesopores and large pores, and are widely used in water treatment, air purification, catalyst carriers and other fields; activated carbon fibers have the characteristics of high specific surface area, developed micropores, and fast adsorption and desorption rates. , Widely used in high-demand occasions such as solvent recovery, water treatment, and air purification. However, the preparation cost of activated carbon fiber is too high, the mesoporosity is low, and the subsequent processing is difficult. Its single form and inconvenient filling highlight various defects in its practical application. Especially in the application of water treatment and catalyst carrier, the mesopor...

Problems solved by technology

However, the preparation cost of activated carbon fiber is too high, the mesoporosity is low, and the subsequent processing is difficult. Its form is single and filling is inconvenient, which highlights its various defects in practical application.

Especially in the application of water treatment and catalyst carrier, the mesoporosity, filter material or the strength of the carrier itself and slag seriously limit the application range of activated carbon fiber
