Performance of TSA and VSA post-combustion CO2 capture processes with a biomass waste-based adsorbent

Biomass Waste Carbon Materials as adsorbents for CO2 Capture under Post-Combustion Conditions

A series of porous carbon materials obtained from biomass waste have been synthesized, with different morphologies and structural properties, and evaluated as potential adsorbents for CO2 capture in post-combustion conditions. These carbon materials present CO2 adsorption capacities, at 25°C and 101.3 kPa, comparable to those obtained by other complex carbon or inorganic materials. Furthermore,...

Water Vapor Adsorption on Biomass Based Carbons under Post-Combustion CO2 Capture Conditions: Effect of Post-Treatment

Energy Savings Potential through Waste Heat Recovery from Flue Gas for Post Combustion Co2 Capture

Flue gas from a plant using fossil fuels contains CO2. Thus power/process plants using fossil fuels contribute to climate change if CO2 in flue gas is not captured. The process of CO2 capture from flue gas is called „postcombustion‟ CO2 capture. Existing plants may be retrofitted with this process to minimize CO2 emission. Amine solutions are mostly used for this process to scrub the flue gas. ...

Post-combustion CO2 capture with a commercial activated carbon: comparison of different regeneration strategies

A commercial activated carbon supplied by Norit, R2030CO2, was evaluated as CO2 adsorbent under conditions relevant to post-combustion CO2 capture (ambient pressure and diluted CO2). It has been demonstrated that this carbon possesses sufficient CO2/N2 selectivity in order to efficiently separate a binary mixture composed of 17 % CO2 in N2. Moreover, this carbon was easily completely regenerate...

Optimal conception of a post-combustion CO2 capture unit with assessment of solvent degradation

The combination of growing energy demand and environmental concerns has made the development of CO2 capture and storage technologies a necessity for the near-future energy mix. Post-combustion CO2 capture is one of the most mature technologies for reducing CO2 emissions in power plants. As a next step for the technology development, large-scale demonstration capture plants have to be implemente...
