Abstract
The performance of a new dry CO2 sorbent KEP-CO2P2 was tested for an extended period of time of 650 hours in a 0.5 MWe CO2 capture test bed at Hadong coal-fired power plant. The mass-produced CO2 dry sorbent, KEP-CO2P2 was tested for CO2 sorption and regeneration capacity. With modification of the process as well as the use of KEP-CO2P2 sorbent in a 0.5 MWe CO2 capture test bed, 85% (81-90%) CO2 removal rate was achieved in continuous operation of 650 hours. Samples were collected and analyzed using particle size analyzer (PSA), ion chromatograph (IC), inductively coupled plasma (ICP), field emission-scanning electron Microscope (FE-SEM), electron probe X-ray micro-analyzer (EPMA) and X-ray diffractometer (XRD). The analysis showed that KEP-CO2P2 was not affected by SOx, and there were no side reactions to consume K2CO3. However, the regeneration of the sorbent was not complete_x000D_
to need future investigation.
