Characteristics of Cyclic Calcination/Carbonation Reaction of Ca-based Absorbent
摘要
Abstract
Aiming at the effects of cycle number,absorbent particle size,CO2 concentration in calcinations,carbonation atmosphere and water vapour concentration on characteristics of cyclic calcination/carbonation reaction of Ca-based absorbent,they are investigated experimentally on a lab-scale setup. The results show that the carbonation conversion of Ca-based absorbent decreases from 72% to 30% after 10 cycles in the calcination/carbonation reaction. The small particle size can improve the carbonation conversion of absorbent. The increase of CO2 concentration in carbonation atmosphere can restrain the decrease of conversion rate in carbonation process. The increase of CO2 concentration in calcination atmosphere can accelerate the decrease of the conversion rate in carbonation conversion process,which results in the decrease of cycle performance for CO2 capture. Water vapour reduces the energy barrier of the diffusion across the solid production,which prolongs carbonation reaction time and increases conversion rate.关键词
