Analysis of Biomass Blend Co-Firing 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

Systems Analysis of Ionic Liquids for Post-combustion CO2 Capture at Coal-fired Power Plants

The main objective of this study is to investigate the feasibility and costs of ionic liquid (IL)-based CO2 capture systems at pulverized coal-fired (PC) power plants. The IL selected for this assessment is trihexyl(tetradecyl)phosphonium 2-cyanopyrrolide ([P66614][2-CNpyr]), achieving a 1:1 and reversible chemical reaction between [2-CNpyr] and CO2. A multi-stage equilibrium-based modeling fra...

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

The effect of post-treatment upon the H₂O adsorption performance of biomass-based carbons was studied under post-combustion CO₂ capture conditions. Oxygen surface functionalities were partially replaced through heat treatment, acid washing, and wet impregnation with amines. The surface chemistry of the final carbon is strongly affected by the type of post-treatment: acid treatment introduces a ...

Ash Deposition in Biomass Combustion or Co-Firing for Power/Heat Generation

This paper presents a concise overview of ash deposition in combustion or co-firing of biomass (woody biomass, agricultural residues, peat, etc.) with other fuels for power/heat generation. In this article, the following five research aspects on biomass combustion ash deposition are reviewed and discussed: influence of biomass fuel characteristics, deposit-related challenges, ash deposition mon...
