Activated carbon immunity
Using small activated carbon fixed bed adsorption gas phase dioxin test bench, a typical activated carbon adsorption dioxin factors affecting the experimental study, discusses the types of dioxin adsorption activated carbon and activated carbon fixed bed adsorption gas phase characteristics of dioxins, and discusses the adsorption temperature and adsorption time of activated carbon adsorption of dioxins.The results showed that the specific surface area and micropore volume of activated carbon had weak correlation with the adsorption efficiency of dioxins.
The mesopore volume of activated carbon is an important factor to determine the adsorption capacity of dioxins. The surface area of the pore size between 2 nm and 20nm plays a key role in the adsorption of dioxins.The higher the adsorption temperature, the lower the adsorption efficiency of activated carbon.The longer the adsorption time, the lower the adsorption efficiency of activated carbon.There is no selective adsorption of gaseous dioxins in activated carbon fixed bed.https://www.dxdcarbon.com/
Microwave method, microwave method is not independent of the physical method and chemical method of the preparation of activated carbon, but on the basis of the physical method and chemical method instead of the traditional heating method, but it has a very significant effect.
Microwave refers to the electromagnetic radiation located between far-infrared and radio waves in the electromagnetic spectrum, with a frequency range of 300MHz to 300GHz and a wavelength of 1m to 1mmMicrowave generates "internal friction heat" through high frequency reciprocating motion of dipole molecules in the heated body, which raises the temperature of the material. It does not require any heat conduction process, and has the characteristics of high efficiency, selectivity, non-contact, integrity, uniformity, quick start and stop, and easy operation Studies have shown that activated carbon can effectively absorb microwave energy and make the temperature rise to 110o℃5' within a...
