In this work spent limestone-based sorbents, generated in fluidized-bed desulphurization tests under simulated combustion conditions, were reactivated by means of a hydration process at 25°C (for times ranging from 1 to 24 h) and further reinjected in the fluidized-bed reactor. The final calcium conversion degrees of resulphated sorbent particles were related to the redistribution of sulphur inside the spent sorbent particle structure and to a “molecular cramming” phenomenon, both dependent on the hydration reaction time.

Abstract
In this work spent limestone-based sorbents, generated in fluidized-bed desulphurization tests under simulated combustion conditions, were reactivated by means of a hydration process at 25°C (for times ranging from 1 to 24 h) and further reinjected in the fluidized-bed reactor. The final calcium conversion degrees of resulphated sorbent particles were related to the redistribution of sulphur inside the spent sorbent particle structure and to a “molecular cramming” phenomenon, both dependent on the hydration reaction time.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
