Wood activated carbon

Activated carbon is a black porous solid carbon, coal by crushing, molding or with uniform coal particles by carbonization, activation production. The main component is carbon, and contains a small amount of oxygen, hydrogen, sulfur, nitrogen, chlorine and other elements. The specific surface area of ordinary activated carbon is between 500 and 1700m/g. Has a strong adsorption performance, for a very wide range of industrial adsorbent.

Product Description

Activated carbon is a black porous solid carbon, coal by crushing, molding or with uniform coal particles by carbonization, activation production. The main component is carbon, and contains a small amount of oxygen, hydrogen, sulfur, nitrogen, chlorine and other elements. The specific surface area of ordinary activated carbon is between 500 and 1700m/g. Has a strong adsorption performance, for a very wide range of industrial adsorbent.

Due to the different sources of raw materials, manufacturing methods, appearance shapes and applications, there are many types of environmentally friendly activated carbon. So far, there are no accurate statistical materials, and there are about thousands of varieties.

According to the source of raw materials:

1. Wood activated carbon

2. Animal bone, blood charcoal

3. Mineral raw material activated carbon

4. Activated carbon from other raw materials

5. Regenerated activated carbon

According to the manufacturing method:

1. Chemical activated carbon (chemical carbon)

2. Physical method of activated carbon

3. Chemical-physical method or physical-chemical method activated carbon

According to the appearance of the shape points:

1. Powdered activated carbon

2. Granular activated carbon

3. Unshaped granular activated carbon

4. Cylindrical activated carbon

5. spherical activated carbon

6. Other shapes of activated carbon

Main features:

Activated carbon is a very small carbon particles have a large surface area, and there are finer pores in the carbon particles-capillary. This capillary has a strong adsorption capacity, due to the large surface area of the carbon particles, so it can be fully contacted with the gas (impurities). When these gases (impurities) encounter capillary adsorption, purification. The surface area of activated carbon research is very important, the specific surface area of activated carbon detection data only by BET method to detect the results are true and reliable, there are many domestic instruments can only do direct contrast method of detection, and now the domestic has been eliminated. At present, the specific surface area test at home and abroad adopts the multi-point BET method, and the specific surface area determination standards formulated at home and abroad are based on the BET test method. Please refer to the Chinese National Standard (GB/T 19587-2004)-The method for determining the specific surface area of solid substances based on the principle of gas adsorption BET. Specific surface area detection is actually a time-consuming job. Due to the different adsorption capacity of samples, the testing of some samples may take a whole day. If the testing process is not fully automated, the testers cannot leave at all times, and they must be highly concentrated. Observing the dashboard and controlling the knob, a little carelessness will lead to the failure of the testing process, which will waste a lot of valuable time of the testers. The F-Sorb 2400 specific surface area tester is an instrument that can truly realize the detection function of BET method (both direct comparison method). More importantly, the F-Sorb 2400 specific surface area tester is the only fully automated and intelligent specific surface area detection equipment in China so far. Its test results are highly consistent with the international ones, and its stability is also very good. At the same time, it can reduce human errors and improve the accuracy of test results.
