The use of solid sorbents for precombustion CO2 capture, which implies the removal of CO2 from the shifted-syngas prior to electricity generation, has acquired increasing interest in recent years. As an alternative method for precombustion CO2 capture, adsorption can be considered a promising technology, offering potential energy savings compared to absorbent systems. Solid sorbents are currently used in pressure swing adsorption (PSA) systems for the purification of hydrogen in petrochemical industries. In the present work, phenol formaldehyde resin-based adsorbents have been prepared to be applied in precombustión CO2 capture applications. The produced carbons showed superior performance when compared to commercial CO2 adsorbents and a great selectivity towards CO2.
