Honeycomb activated carbon is a new type of activated carbon solution with high adsorption and environmental, Honeycomb activated carbon /charcoal use high-quality coal based activated carbon as raw material, with the bee die pressing, high-temperature activation firing to refine. Advantages: (1)Honeycomb shape could be cubes, round cylinders, oval, square and rectangular cylinders, holes density could be 100 to 300 cells per square inch. (2)It is possible to reduce gas purification system size and energy consumption with application of honeycomb carbon, especially to those high flow rate, low-concentration pollutant air streams devices. (3)The pollutants can be removed by honeycomb activated carbon: benzene, , acetone, ethanol, aether, carbinol, acetic acid, ethyl ester, cinnamene, chlorine, phosgene, foul gas, butane, etc.
