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.
