Effect of dolomite decomposition under CO2 on its multicycle CO2 capture behaviour under calcium looping conditions.
One of the major drawbacks that hinder the industrial competitiveness of the calcium looping (CaL) process for CO2 capture is the high temperature (∼930-950 °C) needed in practice to attain full calcination of limestone in a high CO2 partial pressure environment for short residence times as required. In this work, the multicycle CO2 capture performance of dolomite and limestone is analysed unde...
متن کاملLimestone Attrition during Fluidized Bed Calcium Looping Cycles for Co2 Capture: the Effect of So2
Attrition of six different limestones was studied during calcium looping cycles for CO2 capture in a lab-scale fluidized bed apparatus. The tests were carried out under realistic conditions representative of a process with calcination in an oxy-firing environment. The focus of the activity was to investigate the effect of the presence of SO2 both in the calcination and in the carbonation stages...
متن کاملCO2 multicyclic capture of pretreated/doped CaO in the Ca-looping process. Theory and experiments.
We study in this paper the conversion of CaO-based CO2 sorbents when subjected to repeated carbonation-calcination cycles with a focus on thermally pretreated/doped sorbents. Analytical equations are derived to describe the evolution of conversion with the cycle number from a unifying model based on the balance between surface area loss due to sintering in the looping-calcination stage and surf...
متن کاملQuantifying the efficiency of CO2 capture by Lewis pairs.
A microfluidic strategy has been used for the time- and labour-efficient evaluation of the relative efficiency and thermodynamic parameters of CO2 binding by three Lewis acid/base combinations, where efficiency is based on the amount of CO2 taken up per binding unit in solution. Neither tBu3P nor B(C6F5)3 were independently effective at CO2 capture, and the combination of the imidazolin-2-ylide...
