Modification of CaO by Organic Alumina Precursor for Enhancing Cyclic Capture of Greenhouse Gas
Publication: Journal of Environmental Engineering
Volume 135, Issue 6
Abstract
The modification of CaO sorbent with organic alumina precursor to enhance the sorption capacity during cyclic capture is demonstrated in this study. The results indicate that during the sorption time for each cycle, the sorption capacity of original CaO sorbent is significantly decreased from 0.27 to 0.19 and sorbent after 5 and , respectively. On the other hand, the organic alumina modified CaO has a fresh capacity of sorbent, it increases to sorbent after , and then decreases to around sorbent after . When increasing the sorption time to at the 66th cycle, the sorption capacity of original CaO is 0.2, whereas it is sorbent for organic alumina modified CaO. The results demonstrate that by adding only 5% by weight of species into the CaO sorbent, the sorption capacity can be enhanced up to by weight.
