A new honeycomb carbon monolith for CO2 capture by rapid temperature swing adsorption using steam regeneration

A rapid process for CO2 capture is of key importance for the economic feasibility of the process in industry, consequently short adsorption/desorption cycles are crucial. With this aim in mind, a carbon based honeycomb monolith was evaluated for CO2 capture in a thermal swing adsorption process at s...
