Industrial activated carbons covering fields and applications
1 Functional activated carbon activated carbons
Activated carbon is an important functional material for national economic development and national defense construction. Activated carbon can be used for gas phase adsorption, liquid phase adsorption, electronic materials, medical treatment and many other aspects, and can be used as a catalyst and catalyst carrier. In recent years, with the rapid development of environmental protection, new energy and other industries, the market demand for functional activated carbon has surged.
2 Activated carbon modification
Industrial development has increased the requirements for the adsorption capacity and catalytic activity of activated carbon. Conventional activated carbon can no longer meet the special requirements of various fields, and super activated carbon has emerged as the times require. Super activated carbon has a huge specific surface area and excellent adsorption performance, so it is widely used in fuel gas adsorption and storage, gas separation, catalyst carrier, electrode material of super capacitor and so on. In many applications, special activated carbon has also appeared, such as nickel-coated activated carbon suitable for removing alkyl sulfides in gas or exhaust gas, and special activated carbon for citric acid. Although the advantages of super activated carbon are obvious, the application of shortcomings is insufficiently studied, especially in the process of preparation and use, there are still some shortcomings that need to be further studied and improved.
Activated carbon modification is to adjust its adsorption performance, adsorption capacity, catalytic activity and other properties to meet specific working conditions and application conditions. The modification of the adsorption performance of activated carbon is currently mainly focused on two aspects. One is to develop activated carbon with special properties, such as activated carbon fiber and wood activated carbon. The other is to modify the activated carbon to adjust the pore structure of activated carbon to improve the specific adsorption properties. Absorption capacity or desorption capacity.
Activated carbon fiber (ACF) is the third-generation activated carbon product. It can be made into products of any shape, which can be decolorized and deodorized. It is suitable for solvent recovery devices, water purifiers, ozone filters, anti-virus masks, medical bandages, cigarette filters, Precious metal recovery equipment, etc. ACF is mainly used to treat micro-polluted raw water and low-concentration wastewater. One of the main reasons limiting its wide application is the high price.
