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 few minutes. coal based activated carbon price  Study and application of additives in the preparation of activated carbon https://www.granular-activated-carbon.com/  The porous structure of activated carbon determines that activated carbon has many excellent properties. Different pore size distribution can play its corresponding function. Therefore activated carbon is widely used in air purification, water treatment and environmental aspects, such as catalyst and 6 carriers [[68, water treatment, etc. The activated carbon adsorption performance to a large extent depends on the pore structure characteristics, the processing of different objects, different requirements for the distribution of pore structure [7071]. This objectively requires the distribution of the activated carbon pore structure should be diversified. At the same time, pore structure and surface chemical properties of activated carbon can be improved by using the method of chemical physics modification!, this is to pass on the modified activated carbon to its better performance. In the process of carbonization and activation, Adding appropriate chemical reagents will play the role of catalytic oxidation [73], and these chemical reagents will also increase the active point of activation reaction, which is conducive to the development of activated carbon pores.

Principle of activated carbon adsorptionactivated carbon powder suppliers  activated carbon is a kind of very small granular has a large surface area, and more tiny holes in the granular - capillary. The capillary has very strong adsorption capacity, due to the granular surface area is large, so a good contact with with gas (impurities). When these gases (impurities) encounter capillary by adsorption, purification effect. Activated carbon surface area of the study is very important, only the BET specific surface area detecting data of active carbon method detected result is reliable, domestic at present there are many instruments can only make direct comparison method of detection, Plant waste is mostly made of plant fiber raw materials, in the plant body under the action of capillary, modified solution absorbed by material whole fully, between fiber is filled with the subtle space, make the dry material volume expansion after soaking wet, and reaction. Because of the water in the raw material, modified solution constitute a polar molecule, with a strong absorption of microwave dielectric properties,Therefore, polar molecules collide and rub violently with microwave frequency, generating a large amount of heat, which makes water and modified solution volatilize rapidly, and generate steam pressure, which explodes out from the inside of the raw material to the outside. This sharp action makes the fiber space of the raw material expand and produce sharp drying.In this way, the raw material has a more obvious pore structure and a larger internal specific surface area than before microwave irradiation. Compared with the traditional heating method, the mechanism of microwave in the preparation process of activated carbon is completely different.It shows its unique advantages: high efficiency, energy saving, uniformity, selectivity, low pollution, high thermal efficiency, low energy consumption, simple process and equipment and small footprint, conducive to automation, low carbon loss, and recovery of useful substances. https://www.activated-carbon-pellets.com

Due to the presence of specific surface oxygen-containing compounds or complexes, activated carbon has catalytic activity for a variety of reactions, such as the formation of phosgene from chlorine and carbon monoxide.www.activated-carbon-pellets.com   Due to the formation of complex between activated carbon and the host, the complex catalyst increases the catalytic activity. For example, the activated carbon containing palladium salt, even without the presence of copper salt catalyst, the oxidation reaction of ene can also be catalyzed, and the speed is fast and the selectivity is high. cost of powdered activated carbon  Because activated carbon has developed fine pore structure, huge internal surface area and good heat resistance, acid resistance, alkali resistance, can be used as a catalyst carrier. For example, in organic chemistry, hydrogenation, dehydrogenation, cyclamation, isomerization and other reactions, activated carbon is an excellent catalyst for platinum, palladium. Mechanical property of activated carbon (1) particle size: a set of standard screening method is used to calculate the weight of activated carbon left and passed through each sieve, indicating particle size distribution. (2) static density or heap density: diet pore volume and intergranular space volume of the weight of activated carbon per unit volume. (3) volume density and particle density: the weight of activated carbon per unit volume of the diet of pore volume rather than the diet of intergranular space volume. (4) strength: that is, the crushing resistance of activated carbon. (5) wear resistance: that is, wear resistance or abrasion resistance. These mechanical properties directly affect the application of activated carbon, for example: density affects the size of the container; The thickness of powder carbon affects filtration; The distribution of particle size affects the fluid resistance and pressure drop. Fragmentation affects the service life of activated carbon and regeneration of waste carbon.

When the temperature is below 600℃, the specific surface area of carbonized material increases with the increase of temperature.When 600~900℃, the specific surface area reaches a certain value: 250~300 m2/g; when above1000℃, the specific surface area shrinks rapidly. When the carbonization temperature is above 800℃, the reaction performance of carbonized compounds and activation gas gradually becomes weaker, so the carbonization temperature is generally below 1000℃.
