摘要: The modification of CaO sorbent with organic alumina precursor to enhance the sorption capacity during cyclic capture is demonstrated in this study. results indicate that 10 min time for each cycle, C O2 original significantly decreased from 0.27 0.19 and 0.12 g ∕g after 5 60 cycles , respectively. On other hand, modified has a fresh 0.22 sorbent, it increases 0.24 then decreases around 0.15 . When increasing at 66th 0.2, whereas 0.26 CaO. demonstrate by adding only 5% weight Ca12 Al14 O33 species into can be enhanced up ∼27% weight.
