Abstract

Ammonia-based carbon capture process is one of the promising technologies for CO2 mitigation. However, it has a problem to be solved for practical implementation due to the high volatilityof ammonia, which incurs ammonia lose during regeneration. Effects of Fe3+ or Co2+ on ammonia escape and CO2 desorption in NH4HCO3 solution decomposition process were investigated. The results showed that, the addition of metal ion noticeably decreased ammonia escape and slightly increased desorption proportion due to the complexation of metal ion and free ammonia.The metal ion added also promoted desorption rate in this process. Moreover, metal ion Fe3+ is more effective than Co2+ on CO2 desorption and ammonia escape in the regeneration process.
