The report discusses making improved ('super-sorbent') calcium based sorbents commercially for EPA's LIMB (Limestone Injection in Multistage Burners) process for SO2 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 SO2; and (2) manufacturing Ca(OH)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).
