Abstract

A regenerative process for fluidized-bed combustion of coal with lime additives has been investigated. This process is based on using carbon for lime regeneration from the sulfated limestone. Ten sulfation/regeneration cycles using Greer limestone have been conducted in a TG system and there was no sign of weakening of the S0₂ sorption activity. Kinetic and mechanistic studies on the regeneration reaction have also been performed, which included the effects of temperature, water vapor, particle size, and catalysts such as sodium chloride.
