Description

Technical field [0001] The present invention belongs to the technical field of adsorption materials, and specifically relates to a concentrated runner adsorption material, and also relates to a preparation method of the aforementioned adsorption material. Background technique [0002] The volatile organic compounds (VOCs) emitted by industrial production processes directly or indirectly constitute atmospheric haze, which is the key pollutant for air pollution control. With the increasingly stringent environmental regulations, VOCs emitted by industries such as chemicals, machinery, building materials, furniture, optoelectronics, printing, coating, food, medicine, and pesticides are characterized by low concentration and large air volume. Traditional treatment methods such as adsorption and absorption , Regenerative Oxidation Combustion (RTO / RCO), condensation, membrane separation, biological oxidation, plasma, etc., cannot achieve efficient treatment at low operating costs. In or...
