STUDY ON THE CARBONATION REACTION OF Ca-BSASED ABSORBENT
摘要
Abstract
The reaction characteristics of CaO absorbing CO2 were investigated by discussing the influence of reaction conditions on the carbonated reaction and analyzing the dynamic property with unreacted shrinking core model. The results showed that the chemical reaction rate constant of the carbonation reaction is nearly a constant at 650 'C-750 'C; the product layer diffusion coefficient increasing with the increase of temperature; the activation energy of chemical reaction control section was E. = 29. 70 kJ/mol, and of the product control section was Ez = 92. 80 kJ/mol; with the volume fraction of CO2 increasing, the reaction rate and conversion rate increased.关键词
