Abstract

A proton hop supported gas adsorption/desorption of carbon dioxide (CO₂) gas molecules in a sorbent powder is provided. The proton hop supported gas adsorption/desorption includes a configuration of liquid wetting amine particulate grains which is sufficient to suppress carbamic acid production from present CO₂ gas molecules in favor of carbonate production. Thereafter, CO₂ gas molecules interact with the liquid in proximity to an ingress surface of respective ones of the grains. Protons of the liquid proton hop from one amine location of a grain to another in correspondence to the progressive binding of resulting carbonates formed from the CO₂ gas molecules and the hydroxyls of the liquid, from locations nearest to the ingress surface towards locations nearest to an egress surface of the grains. The protons then rejoin with counterpart hydroxls reforming the liquid, whilst the CO₂ gas molecules each are released at the egress surface into a sequestration container.
