NOVELTY - Carbon dioxide adsorbent, comprises 1 pts. wt. cement, 0.25-1 pts. wt. amine substance, 0.25-1 pts. wt. carrier, 0.01-0.03 pts. wt. auxiliary agent and 0.5-2 pts. wt. water. USE - Carbon dioxide adsorbent used for adsorption removal of carbon dioxide in a low humidity environment of ≤50% or less, or high humidity environment greater than 50% (all claimed). ADVANTAGE - The preparation method is simple and easy to implement, eco-friendly and suitable for mass production and industrial application. The prepared carbon dioxide adsorbent has good mechanical strength, and applied to adsorption and removal of carbon dioxide in a high-humidity environment, is easy to activate and regenerate and recycled. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: A method for producing a carbon dioxide adsorbent, which involves: carrying out dry dispersion loading on an amine substance on a carrier by adding amine substances into a carrier material, and then uniformly mixing the materials by adopting equipment to obtain a mixed material 1, where apparatus comprises crusher or a stirring mixer or a kneader. The mixed material and cement are uniformly mixed by adopting the equipment to obtain a mixed material 2. The auxiliary agent and water are introduced, adopted the equipment, uniformly mixed the mixed material 2 and the auxiliary agent powder, and then introduced water, where water is introduced before the formation of the adsorbent or in the formation process of the adsorbent according to a specific forming mode. The auxiliary agent powder is dissolved in water to form an auxiliary agent aqueous solution, and introduced the mixed material 2 into the auxiliary agent aqueous solution before or during the forming process. The rolling ball or extruding strip or tabletting adsorbent forming method is used to form a granular adsorbent, where granules comprise balls, strips or tablets, or the concrete is molded by adopting a concrete molding method of mold entering and compaction, so that the integral, honeycomb or granular adsorbent is formed. The hydration maintenance is carried out on the formed adsorbent, and sealed the adsorbent or opening the adsorbent in the environment in the process, preferably sealing the adsorbent. The humidity of the curing environment is maintained to be more than 95% in the curing process, maintained for 1-10 days to obtain a material after maintenance, and drying the cured material to obtain the carbon dioxide adsorbent. A carbon dioxide adsorbent produced by the production method. A method for activating and regenerating the carbon dioxide adsorbent, which involves heat-treating fresh or using carbon dioxide adsorbent in an air stream or an inert gas stream at a temperature of 80-120℃ for 0.5 hour-1 day. Use of the carbon dioxide adsorbent for adsorption removal of carbon dioxide.
