Apricot Stone |
Using mainly qualified coconut shell and apricot stone shell as raw material, this series of activated carbon are made through physical activation in Slep furnace. The products possess such privileges as well-developed void construction, high intensity, low impurity content, regular grain size, little resistance, easy regeneration, etc.
The products are very effective in water purification. It can be widely used in filling several of water treatment equipment, and in decolorization and refinement of sugar and soft drinking water, and indoor/outdoor air purification. Especially the activated carbon added with special ingredient is very effective in purifying indoor hazardous air such as ammonia, formaldehyde, etc.
Activated carbons are being increasingly used in the field of hydrometallurgy for the recovery of gold and silver and other inorganic and as catalysts and catalyst supports. The carbon granules were directly added to the cyanide pulp and moved countercurrent to it. The gold-loaded carbon was recovered by screening. The applicability of the process is further enhanced by the availability of large quantities of more suitable activated carbons with large surface areas and varied porous structures.
