Coconut Activated Carbon Marketing Is Changing In Recent Years.
Coconut activated carbon is the best quality, that's recognized worldwide.
Coconuts hell based activated carbon is a carbonaceous, highly porous adsorptive medium that has a complex structure composed primarily of carbon atoms. The networks of pores in activated carbons are channels created within a rigid skeleton of disordered layers of carbon atoms, linked together by chemical bonds, stacked unevenly, creating a highly porous structure of nooks, crannies, cracks and crevices between the carbon layers.
Coconut shell based activated carbons are manufactured from coconut shell, High Temperature Steam Activation mechanisms are used in the production of activated carbons from these raw materials,such us Xingyuan 5th+ generation rotary kiln, which is an multi-steam injection activated carbon making kiln.
Activated carbon rotary kiln
The intrinsic pore network in the lattice structure of activated carbons allows the removal of impurities from gaseous and liquid media through a mechanism referred to as adsorption. This is the key to the performance of activated carbon.
And the coconut activated carbon with many different quality for different application , from different mesh size , iodine value ,hardness ect.
|COCONUT SHELL BASED GRANULAR ACTIVATED CARBON|

But recently years ,the coconut activated carbon raw material , coconut shell and shell charcoal , price more and more higher ,from 2010 to now the price is rise twice ,from 250USD to 550USD per ton ,by FOB south east countries , like Indonesia ,Philippine ,Thailand ... but in the same time ,another type of activated carbon coal based activated carbon take more lower and middle market course it's lower price and big quantity .
So some one said coconut activated carbon is loosing it's market recently years . but the truth is no . now coconut activated carbon still have big percentage in market ,but the market is changed into more higher quality ,such like 1200mg/g -1500 mg/g iodine value . which CTC 60%-70% , can used for air pollution control .
Coconut shell based activated carbon with best hardness and 1000mg/g iodine value is also the best choice for gold mining market .
But coal based activated carbon only can do in 400-900mg/g iodine value and hardness not good .
The most important thing is the coconut activated carbon is more suitable for regeneration , but coal based can not ,or not worth to regeneration .
In the future ,the shell based also have it's big space to exist, but will faced into high quality and renewable market .
