carbon adsorbent, method of manufacturing a carbon material for CO2 capture, CO2 capture apparatus and CO2 capture method

摘要

pyrolyzed carbon adsorbent having utility for co2 uptake and methods of making and using a pyrolyzed carbon adsorbent particle form having the following characteristics: (a) co2 capacity exceeding 105 cc / g in a pressure bar and a temperature of 273 ° kelvin, (b) co2 working capacity exceeding 7,0 weight percent, (c) co2 adsorption and desorption heats, each of which is in the range 10 to 40 kj / mol, and (d) the henry co2 / n2 separation factor law greater than 5. the pyrolyzed carbon material may be formed from a polyvinylidene or chloride copolymer-based polymer or other suitable resin material to provide a adsorbent which is useful for carbon dioxide capture applications, for example in the treatment of flue gases from coal-fired power plants.
