Kinetics and structural evolution of sorbents at high temperatures. Final report, September 1, 1994--February 29, 1996

The focus of this project is on furnace sorbent injection technology using dry calcium-based sorbents for the flue gas desulfurization. The goal is to provide fundamental research kinetics and effects of sorbent properties, aimed at improving SO{sub 2} removal and increasing sorbent utilization in a cost-effective manner. The fifth year project work has been carried out in two phases: (1) modified sorbent studies to understand the influence of sorbent modifications (both physical and chemical) on reaction mechanisms, and (2) development of a comprehensive sulfation model to interpret and predict short-time simultaneous calcination, sulfation and sintering processes. This report discusses these two phases of research
