Introduction to wood activated carbon

Wood activated carbon is a kind of high quality fuelwood, wood chips, wood blocks, coconut shells, fruit shells and other raw materials, through a specific process of processing activated carbon products. The following is a detailed introduction to wood activated carbon:

I. Product overview

Name: Wood activated carbon

Wood activated carbon

Type: granular, columnar, powder

Characteristics: high strength, low ash content, reasonable aperture distribution, high ignition point

Main processes: physical method, phosphoric acid method, zinc chloride method, etc. (Note: zinc chloride method is now less used, because it may pollute the environment)

Ii. Main uses

Gas phase adsorption: used in ammonia, natural gas, coke oven gas and other syngas in fine desulfurization, dechlorination, as well as VOCs waste gas treatment.

Liquid phase adsorption: widely used in food and beverage, medicine and other fields with high adsorption performance and high product requirements. In addition, in the advanced treatment of sewage, the application of wood powdered activated carbon is also very common.

Organic solvent recovery: used for benzene gas (such as toluene, xylene), acetone recovery in the acetate fiber industry, and CS2 recovery in viscose staple fiber maintenance production.

Catalyst carrier: Wood activated carbon has a huge specific surface area, which is conducive to the high dispersion of the supported catalytic active substances and the preparation of highly active catalysts. At the same time, its strong adsorption capacity also makes it can be used as a catalytic adsorbent.

Three, the main advantages

Long service life: the service life of wood columnar activated carbon is 4-5 times that of ordinary coal-based activated carbon.

Strong adsorption and desorption: Wood activated carbon has high adsorption and desorption, which can significantly improve the recovery rate of solvent.

Cost-effective: suitable for a variety of organic gas recycling places.

Safe to use: high ignition point, safe to use.

4. Technical parameters (some examples)

Iodine value: >900mg/g

Methylene blue adsorption value: ≥120mg/g

Specific surface area: >1000m²/g

Moisture: ≤8%

PH value: 5-7

(Note: The above technical parameters are only examples, the actual product may vary due to production process, raw materials and other factors.)

5. Instructions for Use

Application scenario: Select the appropriate type (granular, columnar, powdered) and model of wood activated carbon according to specific requirements.

Regeneration and replacement: granular activated carbon is usually recycled, while powdered activated carbon is often not recycled. In the process of use, it is necessary to replace or regenerate regularly to ensure the adsorption effect.

Note: In the process of use, it should be ensured that the air circulation is good, so that the wood activated carbon can better absorb harmful substances in the air. At the same time, the wood activated carbon should be avoided in high temperature, humidity or direct sunlight environment.

In summary, wood activated carbon has been widely used in many fields with its excellent performance, and has been widely recognized by the market.
