Description
Aprico Nutshell Granulated Activated Carbon (GAC) can be used for
water purification.
The products are made from high quality raw materials like Coconut
shell, apricot nutshell and walnut shell, and are designedly
producted by drying, charring and high temperature steam
activating. Characterized by large specific surface area, strong
adsorption power, high mechanical strength, and varieties of sizes,
they are widely used in air purification, catalyst carrier,
extraction of noble metal, solvent recovery and decolorization of
medicines, especially in treatment of industrial and drinking
water.
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 °C, 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 °C, usually in the temperature
range of 600–1200 °C. The product is also designed to comply with
all the applicable provision of ASTM standard for coconut activated
carbon.
Application
Except for the mentioned above all, to meet customer's special
requirement, the above listed coconut shell type carbons can be
specially reeatedand made into activated carbon Permeated silver,
Catalyst Support activated carbon for Vinyl Acetate Synthesis,
Activated Carbon for Gold Recovery, etc.
Analysis Method
Analysis Method: Analysis of the product according to the
requirements of GB/T7702-2008, foreign standard reference ASTM
STANDARD FOR ACTIVATED CARBON & AWWA STANDARD FOR ACTIVATED CARBON
and so on.

Advantages
With high quality nut shell raw material and advanced pickling
post-processing technology,the nut activated carbon has low content
of Fe, Na, K, Ca, Mg, Si and High mechanical strength, the product
has characteristic of pore developed, large capacity of pores, good
adsorption properties, low heavy metal content . it is wildly used
in electronics and semicon industry.It has excellent removing
efficiency for hydrogen peroxide, organic matter, Heavy Metal, and
residual chlorine in the recycled water.
