Honeycomb activated carbon can be widely used in various gas purification equipment and waste gas treatment projects. Practice has proved that the purification effect is better than that of ordinary ones. The pollutants that honeycomb activated carbon can remove in different degrees are: nitrogen oxides, carbon tetrachloride, chlorine, benzene, formaldehyde, acetone, ethanol, ether, methanol, ethyl acetate, styrene, phosgene, malodorous gases and other acid-base gases. Nested activated carbon has the characteristics of large area, small through-hole resistance, developed micropores, high adsorption capacity and long service life, and is widely used in air pollution control. Honeycomb activated carbon adsorption method is selected, that is, the waste gas contacts with porous activated carbon with large surface area, and the pollutants in the waste gas are adsorbed and decomposed, thus playing a purification role. It can be used directly, or put into a purification cabinet and an adsorption bed. If the waste gas concentration is high and the emission is large, two purification cabinets and adsorption beds can be used alternately. In the process of use, try to avoid excessive temperature, which will reduce the adsorption capacity, and the adsorption capacity will decrease with the increase of temperature.

At the same time, high dust content and oil mist should be avoided, because tar dust mist will block the micropores of activated carbon, increase resistance and reduce adsorption effect. If the use environment contains a lot of thick dust and tar, pre-stage dust removal and filtration should be installed to achieve the best use effect and the longest service life. Some manufacturers boast that the iodine value of their honeycomb activated carbon can reach 800 or even 1000. As we all know, the raw material of honeycomb activated carbon is powdered activated carbon. The iodine value of conventional coal-based powdered activated carbon can indeed reach 800 or even 1000, but honeycomb activated carbon will also be added during the firing process, which accounts for nearly half of the raw materials. Honeycomb activated carbon with iodine value of 800 or even 1000 will have iodine value of 400-500 after firing, which is not as exaggerated as 800- 1000 boasted by manufacturers.
