    Activated carbon has a large specific surface area, good microporous structure, strong regeneration ability, is a good adsorption material.

    Activated carbon can realize desulfurization and denitration at the same time, no secondary pollution and renewable utilization of resources.

    At present, the adsorption device of activated carbon adsorption process reported in the literature is mainly fixed bed, and this process has the disadvantages of large equipment, large bed resistance, poor continuity and so on.granular activated carbon coconut shell

    In this paper, the activated carbon desulfurization and denitration test bed, with the circulating fluidized bed as the main adsorption device, the activated carbon desulfurization and denitration test study.

    Circulating fluidized bed flue gas purification technology can effectively avoid the shortcomings of the fixed bed adsorption process, such as complex equipment, large space occupied, and unstable bed resistance, etc., and the good cooperation with the bag filter can achieve the continuity of activated carbon adsorption and regeneration.www.wyactivatedcarbon.com
    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.

    Many theoretical problems in this new field, especially the microwave heating mechanism, need to be further studied, and the mathematical model of the heating process needs to be established
