Thermal decomposition study of crystalline limestone

Keywords Limestone; P-wave velocity; Thermal decomposition 1. Introduction The main chemical property of limestone is its ther-mal decomposition, known as ''calcination'', during which quicklime (CaO) and carbon dioxide are pro-duced. It is a reaction that is strongly affected by the partial pressure of the gas phase (PCO 2). An increase in PCO

Study of Limestone Calcination with CO2 Capture

Nov 03, 2007In 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.
