Decomposition Of Limestone

2019-3-9 路 in the present work, The effects of temperature (up to 1293 k) and residence time on the decomposition behaviors of limestone particles (0.25?0.5 mm) in a co2 atmosphere were investigated using a continuously operating fluidized bed reactor for co2 capture. The results show that the rate of limestone decomposition was strongly dependent upon the pressure difference between the.
