  • Activated carbon desulfurization has the advantages of high desulfurization rate, simultaneous denitrification, deodorization, dust removal, and no waste water residue. It is a promising method for flue gas purification. Activated carbon can be regenerated at high temperatures. At temperatures above 350 °C, pollutants such as sulfur oxides, nitrogen oxides, and dioxins adsorbed on activated carbon are rapidly resolved or decomposed (sulphur dioxide is analyzed, nitrogen oxides and dioxins). English is broken down). And as the temperature increases, the regeneration rate of the activated carbon is further accelerated, and the regeneration time is shortened. It is preferred that the activated carbon regeneration temperature in the general control analytical column is approximately equal to 430 ° C. Therefore, the ideal resolution temperature (or regeneration temperature) is, for example, at 390. -450 ° C range, more preferably in the range of 400-440 ° C.
