What are the types of wood activated carbon?

Wood activated carbon is wood chips, wood blocks, bamboo, fruit shells, coconut shells and other carbon-rich organic materials as raw materials, through a specific process of processing activated carbon products. There are many kinds, which can be mainly divided into the following categories:

1. Classification by shape

Granular wood activated carbon:

Granular wood activated carbon is a more common form, with larger specific surface area and better adsorption properties.

Columnar wood activated carbon:

Columnar wood activated carbon is usually made of powdered raw materials and binders through kneading, extrusion molding, carbonization, activation and other processes, which has high mechanical strength and better adsorption effect.

Powdered wood activated carbon:

Powdered wood activated carbon is actually a finer granular activated carbon, because the particles are small and the specific surface area is large, its adsorption effect is usually better than that of granular activated carbon.

2. Classification by raw materials

Coconut shell activated carbon:

Activated carbon made from coconut shell has the advantages of high strength, developed pore structure, large specific surface area and fast adsorption rate, and is widely used in gas and liquid phase adsorption.

Fruit shell activated carbon:

Including apricot shell activated carbon, walnut shell activated carbon, peach shell activated carbon, etc., made of different kinds of fruit shells as raw materials, with their own unique adsorption properties and application range.

Wood blocks/Wood chips Activated Carbon:

With wood blocks or wood chips as raw materials, through a series of processes processed, with a wide range of raw material sources, relatively low production costs.

Bamboo activated carbon:

The activated carbon made from bamboo has unique pore structure and adsorption properties, which is suitable for a variety of adsorption and purification occasions.

Three, special function wood activated carbon

Silver loaded activated carbon:

Based on fruit shell activated carbon, etc., made of silver loaded by special process, in addition to the adsorption function of ordinary activated carbon, it also has the function of inhibiting bacterial reproduction, and is often used in water purifiers and other fields.

4. Classification of application fields

According to the different application fields, wood activated carbon can be further subdivided into activated carbon suitable for gas phase adsorption, activated carbon suitable for liquid phase adsorption, activated carbon for solvent recovery, etc.

In summary, there are many kinds of wood activated carbon, and different kinds of activated carbon are different in raw materials, shapes, properties and application fields. When selecting wood activated carbon, it is necessary to make comprehensive consideration according to specific needs and conditions.
