文章亮点

(1) MgO加入量多或少都不利于提高钙基吸附剂的CO₂吸附能力，确定适宜的MgO含量是非常有必要的；

(2) 钙基吸附剂的动力学吸附过程存在两个阶段，且第一阶段（反应控制）的活化能低于第二阶段（扩散控制）的活化能；

(3) 钙基吸附剂的“自活化”现象提高了吸附剂的CO₂吸附能力，从而验证了吸附剂中MgO的骨架支撑作用。

中文摘要

中国的钢铁行业面临着钢渣利用和CO₂减排的迫切需求, 而钢渣中的Ca和Mg可以用酸溶液萃取，制备捕集CO₂的吸附剂。本文以渣渗滤液为原料，采用共沉淀法制备了钙基吸附剂，其对CO₂的初始CO₂化学吸附容量为0.40 g/g。此外，本文还研究了Ca/Mg摩尔比对钙基吸附剂的形貌、结构和CO₂化学吸附能力的影响。结果表明对CO₂吸附能力最佳的吸附剂是Ca/Mg摩尔比为4.2:1的, 证明了氧化镁在钙基吸附剂中的骨架支撑作用。通过Avrami-Erofeev模型研究了钙基吸附剂的化学吸附动力学，发现CO₂吸附存在两个过程，且第一阶段（反应控制）的活化能低于第二阶段（扩散控制）的活化能。

Abstract

Abstract

Steelmaking industry faces urgent demands for both steel slag utilization and CO₂ abatement. Ca and Mg of steel slag can be extracted by acid solution and used to prepare sorbents for CO₂ capture. In this work, the calcium-based sorbents were prepared from stainless steel slag leachate by co-precipitation, and the initial CO₂ chemisorption capacity of the calcium-based sorbent prepared from steel slag with the Ca and Mg molar ratio of 3.64:1 was 0.40 g/g. Moreover, the effect of Ca/Mg molar ratio on the morphology, structure, and CO₂ chemisorption capacity of the calcium-based sorbents were investigated. The results show that the optimal Ca/Mg molar ratio of sorbent for CO₂ capture was 4.2:1, and the skeleton support effect of MgO in calcium-based sorbents was determined. Meanwhile, the chemisorption kinetics of the sorbents was studied using the Avrami-Erofeev model. There were two processes of CO₂ chemisorption, and the activation energy of the first stage (reaction control) was found to be lower than that of the second stage (diffusion control).
