Description/Abstract This report discusses making improved (super-sorbent) calcium-based sorbents commercially for EPA`s LIMB (Limestone Injection in Multistage Burners) process for SO/sub 2/ removal from coal-fired utility boilers.^Two processes for making super-sorbents were investigated: (1) precalcination of limestone to produce a stable, isolable CaO sorbent with the ability to react rapidly and extensively with SO/sub 2/; and (2) manufacturing Ca(OH)/sub 2/, in more reactive forms than are now available commercially.^Precalcination seems to have negligible commercial prospects, both technically and economically.^Modified hydrates, on the other hand, received major attention experimentally and is the primary focus of the report.^Three ways to produce more reactive hydrates were investigated, and two classes of permanent additives were investigated: (1) surfactants and dispersants; and (2) common sugar (sucrose).
