A simple one-dimensional mathematical model validated with high- temperature entrained-flow reactor data successfully explained dis- persed calcium hydroxide particle surface area evolution resulting from concomitant calcination and sintering. An integrated first-order calcina- tion rate expression and a second-order sintering rate form accurately predicted time-resolved surface area generation and degradation. The effects of water vapor and gaseous carbon dioxide concentration on asymptotic specific surface areas and sintering rates were noted. This methodology for predicting sorbent surface area evolution will enable more accurate sulfation modeling efforts in furnace sorbent injection (FSI) applications, where calcination, sintering, and sulfation can all occur on the same time scale.
