摘要：

Based on the eggshell waste discarded in the food industry, three kinds of organic calcium adsorbents, including calcium acetate, calcium citrate and calcium gluconate, were prepared using the corresponding organic acids. Their cyclic CO2 capture performance and carbonation characteristics were studied on a tailored dual temperature tubular reactor and thermogravimetric analyzer, respectively. Furthermore, variation of the crystalline phases, structural characteristic and microscopic morphology of the prepared CaO adsorbents over the cyclic CO2 capture process were analyzed. The results indicated that the CaO adsorbent derived from calcium gluconate owned highest reactivity and the most pronounced CO2 capture performance with the first carbonation conversion reaching as high as 85.33%, but it also had smaller crystalline grains of CaO than other absorbents with more developed pores within 20-100nm. After the twenty CO2 capture cycles, the neighboring CaO particles involved were found to melt and agglomerate into larger particles, which resulted in loss of the pore structure and reduced porosity, and thereby its carbon capture performance decayed. © 2022, Chemical Industry Press Co., Ltd.
