Study and application of additives in the preparation of activated carbon

The porous structure of activated carbon determines that activated carbon has many excellent properties. Different pore size distribution can play its corresponding function.gold recovery from activated carbon 

Therefore activated carbon is widely used in air purification, water treatment and environmental aspects, such as catalyst and 6 carriers [[68, water treatment, etc. The activated carbon adsorption performance to a large extent depends on the pore structure characteristics, the processing of different objects, different requirements for the distribution of pore structure [7071]. This objectively requires the distribution of the activated carbon pore structure should be diversified. At the same time, pore structure and surface chemical properties of activated carbon can be improved by using the method of chemical physics modification!, this is to pass on the modified activated carbon to its better performance. In the process of carbonization and activation,activated carbon china manufacturers 

Adding appropriate chemical reagents will play the role of catalytic oxidation [73], and these chemical reagents will also increase the active point of activation reaction, which is conducive to

the development of activated carbon pores.

Now at home and abroad the main research work is mainly the following aspects: a, additive in the functional mechanism of manufacturing activated carbon energy gao jun of China university of mining mechanism of additives in the manufacturing activated carbon made detail [4, pointed out that: the catalyst in the carbonization stage prompted carbon the destruction of the molecular structure of aromatic raw materials, to "structure" of disordering, provides a good initial activation reaction conditions, is an important factor to improve the activation of activated carbon pore. In the process of activation, potassium to strengthen the directionality of the pore, thereby reducing the unnecessary on ignition, and accelerated the process of pore forming,

And pore distribution is given priority to with microporous activated carbon; refractory in the catalyst to ash content of SiO2 and Al, 03, etc, into acid soluble potassium nepheline chemical compounds such as magnesium and calcium silicon stone is the key to improve pickling deliming rate factor b and additives on the activated carbon adsorption properties, pore structure and pore size distribution - adding different additives. The influence of the activated carbon: c, chemicals for coking products.
