The production process of columnar activated carbon is relatively complicated. However, the columnar activated carbon has relatively high iodine value, carbon tetrachloride adsorption capacity and benzene adsorption capacity due to its specific production processes. Therefore, the columnar activated carbon is mostly used for the treatment of organic waste gas with medium and high concentration and low air volume. Due to its higher adsorption performance, the waste gas residence time is longer, and the treatment effect is better. Moreover, another feature of columnar activated carbon is that it has a high regeneration rate and can be recycled, which reduces resource waste to a certain extent.
In addition, in solvent recovery, oil and gas recovery and other industries, most customers choose columnar activated carbon or coconut shell granular activated carbon with higher iodine value. Activated carbon has different pore size and structure due to different raw materials. Wood-based activated carbon has larger pores, while nutshell-based activated carbon has smaller and uniform pores, and coal-based activated carbon is in between. Therefore, for the organic waste gas generated by some special industries, we can select activated carbon of different raw materials to achieve better treatment effects.
