영어 초록
The effects of potentially important process variables in a fly ash/hydrated lime sorbent
producing process on the reactivity of the sorbents were investigated. The process variables
investigated were fly ash/hydrated lime weight ratio, reaction temperature, reaction time and
additive concentration. The fly ash/hydrated lime sorbents were produced in a lab-scale batch
reactor and the reactivity of the produced sorbents was evaluated in terms of SO2 removal
efficiency and sorbent conversion determined in a lab-scale fixed-bed reactor. The experimental
conditions in the sorbent producing process were designed following a 24 factorial design
method and the effects of the process variables were analyzed by ANOVA technique. The
analyses of the experimental results showed that as the fly ash/hydrated lime weight ratio was
increased, the SO2 removal efficiency decreased but the sorbent utilization increased due to the
decrease of the Ca/S ratio with increasing fly ash/hydrated lime weight ratio. It was also shown
that both the SO2 removal efficiency and the sorbent utilization increased with increasing
reaction temperature, with increasing reaction time or with increasing additive concentration
due to the increased rate of silica dissolution at higher reaction temperature and at higher
additive concentration or due to the increased amount of dissoluted silica from fly ash with longer reaction time.
