Activated carbon has a large specific surface area, good microporous structure, strong regeneration ability, is a good adsorption material.
Activated carbon can realize desulfurization and denitration at the same time, no secondary pollution and renewable utilization of resources.
At present, the adsorption device of activated carbon adsorption process reported in the literature is mainly fixed bed, and this process has the disadvantages of large equipment, large bed resistance, poor continuity and so on.
In this paper, the activated carbon desulfurization and denitration test bed, with the circulating fluidized bed as the main adsorption device, the activated carbon desulfurization and denitration test study.
Circulating fluidized bed flue gas purification technology can effectively avoid the shortcomings of the fixed bed adsorption process, such as complex equipment, large space occupied, and unstable bed resistance, etc., and the good cooperation with the bag filter can achieve the continuity of activated carbon adsorption and regeneration.activated carbon suppliers australia
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.Because of the fine particles of powdered activated carbon, it is inconvenient to operate, so in the practical application process, generally try not to use the first kind of active carbon.www.coconutactivatedcarbon.com
No powdered activated carbon is another important reason for the adsorption of powdered activated carbon is too strong, there are many substances adsorbed on it is very difficult to elute, usually will be used after the adsorbent deactivation.
