Cyclic CO2 Capture Performance of Carbide Slag: Parametric Study

摘要：

In this work,CO2 capture performance of carbide slag has been investigated in a thermogravimetric analyzer (TGA).Effects of operation parameters including particle size,reaction temperature and reaction duration on CO2 capture capacity were studied.The experimental results indicate that the increase of particle size ranging from 80~180μm has a positive effect on the CO2 capture capacity of carbide slag.The sorbent reactivity decreases with an increase of calcination temperature.The prolonged exposure to carbonation conditions has a beneficial effect on sorbent behavior as a function of the number of calcination/carbonation cycles;however,the duration in the calcination step has little effect.Based on the experimental results,the reaction rate constant of carbonation reaction is obtained from Jander equation.It is found that it decreases with the increasing cycles.
