基于钙基废弃物的高活性吸收剂合成及其循环捕集 CO2性能
Synthesis of highly reactive sorbent from industrial wastes and its CO2 capture capacity
摘要
Abstract
A kind of industrial solid waste,i.e.,carbide slag, was used as CaO precursor to synthesize CO2 sorbent.The highly reactive synthetic sorbent was prepared from carbide slag,aluminum nitrate hydrate and glycerol water solution by the combustion synthesis method.The results show that the synthetic sorbent exhibits a much higher CO2 capture capacity compared with carbide slag.The CO2 capture capacity and the carbonation conversion of the synthetic sorbent are 0.38 g /g and 0.70 after 50 cycles,which are 1.8 and 2.1 times those of carbide slag.The average carbonation conversion and the CO2 capture efficiency of the synthetic sorbent are higher than those of carbide slag with the same sorbent flow ratios.The required sorbent flow ratios are lower for synthetic sorbent to achieve the same CO2 capture efficiency compared with carbide slag. With the same sorbent flow ratio and CO2 capture efficiency, the energy requirement in calciner for the synthetic sorbent is less than that for carbide slag.关键词
