325 Mesh Iodine 1000 Powder Coal Activated Carbon for Burning smoke
purification/Removing HG,PCDDS,PCDFS,Heavy Metals
Description
The product is one kind of coal-based powdered activated carbon
developed for garbage burning. The production processes are
accomplished by using one combination of the following steps:
1.) Carbonization: Material with carbon content is pyrolyzed at
temperatures in the range of 600–900 ℃, in absence of oxygen
(usually in inert atmosphere with gases like argon or nitrogen)
2.) Activation/ Oxidation: Raw material or carbonised material is
exposed to oxidizing atmospheres (carbon monoxide, oxygen, or
steam) at temperatures above 250℃, usually in the temperature range
of 600–1200℃.
3.) Powdered: After activation, the activated carbon will be
powdered to 325 mesh by special mills.
Applications.
The product is used primarily in burning smoke purification,
removing the heavy metal (especially Hg), PCDDS, PCDFS. This carbon
is a coarser mesh media and is generally used in deep bed filters
where pressure drop may be concerned. It functions as a dual
purpose media provide both filtration and adsorption.

Advantages
Purification of the burning smoke, for this kind of activated
carbon has the function of physical adsorption.Complicated pores
structure provides an equal blend of low and high energy, also for
effective removal of abroad range of high and low molecular weight
organic compounds.Wets readily and do not float, thus minimizing loss during backwash
operations.Create optimal transport paths for faster adsorption.
