Degradation behavior of high surface area .
· Hydrated lime sorbents with a high surface area were prepared by hydration of Diethylene glycolcoated quicklime. A durability test for sorbents was carried out in a consistent chamber condition at a temperature of 50 °C and a humidity level of 60% relative humidity for 168 h. With respect to SO 2 reactivity, the deteriorated sorbents showed lower reactivity toward SO 2 gas than an as ...
