- Abstract
- The influence of temperature on attrition of two limestones during desulfurization in a fluidized bed reactor
was investigated. Differences in the microstructure of the two limestones were reflected by a different
thickness of the sulfate shell formed upon sulfation and by a different value of the ultimate calcium conversion
degree. Particle attrition and fragmentation were fairly small under moderately bubbling fluidization
conditions for both limestones. An increase of temperature from 850 ?C to 900 ?C led to an increase
of the attrition rate, most likely because of a particle weakening effect caused by a faster CO2 evolution
during calcination. This weakening effect, however, was not sufficiently strong to enhance particle fragmentation
in the bed. The progress of sulfation, associated to the build-up of a hard sulfate shell around
the particles, led in any case to a decrease of the extent of attrition. Sulfation at 900 ?C was less effective
than at 850 ?C, and this was shown to be related to the porosimetric features of the different samples. (literal)
