Sustainable biomass-based carbon adsorbents for post-combustion CO2 capture

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

Holey graphene frameworks for highly selective post-combustion carbon capture

Atmospheric CO2 concentrations continue to rise rapidly in response to increased combustion of fossil fuels, contributing to global climate change. In order to mitigate the effects of global warming, development of new materials for cost-effective and energy-efficient CO2 capture is critically important. Graphene-based porous materials are an emerging class of solid adsorbents for selectively r...

Membrane Systems Engineering for Post-combustion Carbon Capture

This study proposes a strategy for optimal design of hollow fiber membrane networks for post combustion carbon capture from power plant multicomponent flue gas. A mathematical model describing multicomponent gas permeation through a separation membrane was customized into the flowsheet modeling package ASPEN PLUS. An N-stage membrane network superstructure was defined considering all possible f...

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...
