This product is mainly used to remove ammonia, methylamine, dimethylamine, trimethylamine, ethylamine and other amine-containing alkaline gases. Because the activated carbon itself is in a weakly alkaline environment during the production process, it is difficult to use its own ability to adsorb alkaline gases to achieve efficient removal. Therefore, in the production process, the pores of the base carbon are adjusted by the pore process control technology to achieve a better ability to carry acidic substances, and the acidic substances are loaded through post-processing. reaction, thereby improving the adsorption effect of the product on alkaline substances.
