Carbon Capture with Enhanced Efficiency

This patent introduces a novel method and composition for enhancing carbon capture and storage by utilizing a mixture of alkali metal carbonates and fully carbonated amines as promoters. The primary aim is to improve the kinetics of CO2 capture from ambient air and other gas mixtures with low CO2 concentrations. Sodium carbonate, a cost-effective and environmentally friendly compound, is the focal point of the patented method, particularly when occurring naturally in trona or formed in solution. The reactive absorption of CO2 is facilitated by the fully carbonated amines, which enhance the reactivity with alkali metal carbonates, improving efficiency and reducing cost-inefficiencies traditionally associated with the slow reaction kinetics of sodium carbonate alone. This innovative approach is expected to make direct air capture (DAC) more feasible, contributing significantly to reducing atmospheric CO2 levels, thus addressing climate change.
