Product Details

Columnar activated carbon description 
 

Columnar activated carbon(cabon pellet, activated carbon pellets) is also called extruded activated carbon, columnar activated carbon, and cylindrial activated carbon. According to different materials, columnar activated carbon is classified two types: wood type and coal type. They are the products what made of powdered nuts shell, woods or anthracites added tar as adhesive after carbontization and activatation, and the appearance is black columnar.

 

Columnar activated carbon classification
 

They are include coal-based columnar activated carbon and wood columnar activated carbon (wood includes coconut shell and wood).

 

Wood columnar activated carbon
 

The coconut shell columnar activated carbon is made of fine wood chips, nuts shell or coconut shell, etc. through crushing, mixing, extrusion, molding, drying, carbonization and activation. Compared with traditional coal-based columnar carbon, it has advantages of lower ash content, less impurities, and higher CTC absort value, etc.

Mainly used:
 
1. Gas phase adsorption.
 
2. Recovery of organic solvents (benzene series gas toluene, xylene, recovery of acetone in the cellulose acetate industry, recovery of CS2 in the production of viscose staple fiber, etc.).
 
3. Removal of impurities and harmful gases.
According to the experimental data of Baiyun Carbon Co., Ltd., 4mm activated carbon has a CTC adsorption rate of 60%, not more than 70%, while the produced 4mm wooden pellet activated carbon has a CTC adsorption rate close to 100%.

Coal based pellet activated carbon

The coal-based pellet activated carbon is made of fine anthracite as raw materials, after series processes. And it has the appearance of black cylindrical particles; it has a reasonable pore structure, good adsorption performance, high mechanical strength, easy repeated regeneration, and low cost. For the purification of toxic gases, waste gas treatment, industrial and domestic water purification, solvent recovery, etc.

Columnar activated carbon feature
 

Columnar activated carbon advantages：


Coconut shell columnar activated carbon has advantages of lower ash content, less impurities, gas phase adsorption value, and higher CTC adsorption.
 
Coal columnar activated carbon has the advantages of developed void structure, large specific area, strong adsorption capacity, high mechanical strength, low bed resistance, good chemical stability, easy regeneration, and durability.
 
The pore size distribution of the product is reasonable to achieve greater adsorption and desorption, thereby greatly improving the service life of the product (average 2-3 years), which is 1.4 times that of ordinary coal-based carbon.
 
Applicability of columnar activated carbon:
 
①Gas phase adsorption;
 
②Organic solvent recovery (benzene series gas toluene, acetone recovery in the cellulose acetate industry);
 
③Removal of impurities and harmful gases, and recovery of waste gas;
 
④Recover excess gasoline in refineries, gas stations, and oil depots;
 
⑤Used to catalyze the removal of HCl from tetrachloroethane on activated carbon to prepare trichloroethylene.
