Abstract

Poor cycling stability is the main bottleneck restricting the development and application of calcium-based CO2 adsorbent.The precursors were prepared from stone powder and steel slag，and the optimum conditions for preparing adsorbent were determined by response surface method.The influence and mechanism of steel slag on the cyclic stability of the adsorbent were studied by calcium cycle testing and SEM，XRD，BET detection.The results showed that the optimum conditions for preparation of the adsorbent were calcination temperature of 860 ℃，calcination time of 95 min，in an air atmosphere，mass ratio of stone powder，steel slag and cement 90:7:3，and at this time the effective decomposition value of the adsorbent was 94.06%.After 35 calcium cycles（GX35），the CO2 adsorption capacity and carbonation conversion rate of the adsorbent with steel slag were 0.426 1 g/g and 78.60%，respectively，which were better than the CO2 capture performance of the adsorbent without steel slag after 20 calcium cycles（SX20）.GX35 contained a relatively large number of pores with diameters ranging from 1 nm to 3 nm and it had a loose sponge-like structure overall，while SX20 contained few pores with diameters below 5 nm and it had a tight structure.The adsorbent with steel slag showed a smaller change in crystal growth and pore structure during the calcium cycle compared to the adsorbent without steel slag.Steel slag could play the role of accelerate decomposition，block separation，disperse limiting，skeleton support and nucleation，inhibited crystal aggregation and particle agglomeration，and reduced pore structure collapse and plugging amplitude，and enhanced the anti-sintering ability and cycle stability of the adsorbent.
