- Abstract
Large particle size limestone (CaCO3) is an important raw material used in many branches of industry. For lacking of reaction parameters of large particle size limestone, numerical analysis method is used to study the decomposition reaction kinetics of limestone to understand the thermal decomposition reaction and obtain dominant parameters of large particle size limestone (20, 30, 40 mm). The results show that the decomposition reactions of three different particle sizes at 900~1000 temperature conform to the phase interface reaction mechanism model (cylindrical symmetry), and the reaction activation energy E is ranging from 30 to 34 kcal/mol and the pre-exponential factor lnA is ranging from 7.5 to 9s-1, which are conference data for practical engineering.
