摘要

在CO

的减排技术中

钙基吸附剂循环捕集CO

由于具有原材料来源广泛、吸附容积大等优点受到越来越多的关注

但钙基吸附剂在循环反应过程中活性会不断衰减。以2种天然前躯体（白云石、石灰石）和3种人工前躯体（葡萄糖酸钙、柠檬酸钙、乙酸钙）制备Ca O吸附剂

对循环曲线进行动力学分析。研究发现以白云石为前驱体制备的吸附剂反应速率较快、循环转化率最高、稳定性好

拟合100次循环后转化率仍高达40%。

Abstract

In the capture CO

process from flue gas

calcium based sorbent has attracted more and more attention because of its advantages of wide source of raw materials and large adsorption capacity. However

its capacity could continue to decrease during the cyclic cycle. In this paper

two kinds of natural precursors（dolomite

limestone） and three kinds of artificial precursors（calcium gluconate

calcium citrate and calcium acetate） were used to prepare high efficiently Ca O sorbents.Moreover

the cyclic kinetic analysis was carried out. It is found that the adsorption rate of dolomite as the precursor is faster

the conversion rate is the highest and the stability is the best. After 100 cycles

its conversion rate can remain at 40%.
