Abstract

The dechlorination test of modified calcium-based sorbent and that of unmodified calcium-based sorbent were compared in a small-scale dual-layer granular bed filter in order to investigate the calcium utilization and dechlorination efficiency. The results showed that the activity of modified calcium-based dechlorinating agent hydrate was greatly increased. When Ca/Cl=2.5, the dechlorination efficiency reached 99% at 600°C, and 80% at 500°C and 700°C, which was significantly higher than that of general sorbent Ca(OH)₂. The calcium utilization of modified calcium-based sorbent was 42.4% at 500°C, 53.8% at 600°C, and 45.7% at 700°C, while that of general calcium-based sorbent was only 36.8% at 600°C.
