Regenerable sorbents have been investigated as an alternative to limestone for the removal of SO<SUB>2</SUB> from fluidized bed combustion. A sorbent prepared by hydration of alumina cement clinker particles at room temperature was developed. Reactivity (sulfation and regeneration) of this sorvent was studied by means of a thermogravimetric analyzer and a small fluidized bed reactor. The SO<SUB>2</SUB> reactivity of the sorbent with above 30 wt% bound water was higher than that of limestone in a range of temperature from 800 to 1, 000°C. Regeneration temperature was lower than that of limestone, and was carried out about 1, 000°C. Also, it was found that for 10 cycles (sulfation/regeneration cycles), the reactivity of the sorbent remained at initial level.
