Title (EN) METAL ORGANIC FRAMEWORKS APPENDED WITH CYCLIC DIAMINES FOR CARBON DIOXIDE CAPTURE
(FR) STRUCTURES ORGANOMÉTALLIQUES AJOUTÉES À DES DIAMINES CYCLIQUES POUR LA CAPTURE DE DIOXYDE DE CARBONE
Abstract:
(EN) Achieving the selective and reversible adsorption of CO2 from humid, low partial pressures streams such as the flue gas resulting from the combustion of natural gas in combined cycle power plants (4% CO2) is challenging due to the need for high thermal, oxidative, and hydrolytic stability as well as moderate regeneration conditions to reduce the energy of adsorption/desorption cycling. Appending cyclic primary, secondary diamines, exemplified by 2-(aminomethyl)piperidine (2-ampd), to the metal–organic frameworks Mg2(dobpdc) (dobpdc4– = 4,4-dioxidobiphenyl-3,3-dicarboxylate), Mg2(dotpdc) (dotpdc4– = 4,4''-dioxido-[1,1':4',1''-terphenyl]-3,3''-dicarboxylate) or Mg2(pc-dobpdc) (pc-dobpdc4– = dioxidobiphenyl-4,4'-dicarboxylate) produces adsorbents of the classes EMM-44, EMM-45, and EMM-46, respectively, that display step-shaped adsorption of CO2 at the partial pressures required for 90% capture from natural gas flue gas at temperatures up to or exceeding 60 °C. Using a cyclic diamine in place of a diamine functionalized with bulky alkyl groups enables fast adsorption/desorption kinetics with sharp CO2 adsorption and desorption steps.
(FR) La réalisation de l'adsorption sélective et réversible de CO2 à partir de courants de pressions partielles basses humides tels que le gaz de carneau résultant de la combustion de gaz naturel dans des centrales électriques à cycles combinés (4 % CO2) est difficile en raison de la nécessité d'une stabilité thermique, oxydative et hydrolytique élevée ainsi que des conditions de régénération modérées pour réduire l'énergie du cycle adsorption/désorption. L'ajout de diamines cycliques primaires et secondaires, illustrées par la 2-(aminométhyl)pipéridine (2-ampd), aux réseaux organométalliques Mg2(dobpdc) (dobpdc4– = 4,4-dioxidobiphényle-3,3-dicarboxylate), Mg2(dotpdc) (dotpdc4– = 4,4''-dioxido-[1,1':4',1''-terphényle]-3,3''-dicarboxylate) ou Mg2(pc-dobpdc) (pc-dobpdc4– = dioxidobiphényle-4,4'-dicarboxylate) produit des adsorbants des classes EMM-44, EMM-45, et EMM-46, respectivement, qui présentent une adsorption de CO2 par paliers aux pressions partielles requises pour une capture de 90 % à partir de gaz de combustion naturels à des températures allant jusqu'à 60 °C ou dépassant 60 °C. L'utilisation d'une diamine cyclique plutôt qu'une diamine fonctionnalisée par des groupes alkyles volumineux permet une cinétique d'adsorption/désorption rapide avec des phases d'adsorption et de désorption précises de CO2.
