摘要:

针对CO2排放及高炉渣资源超负荷储存带来的环境问题,探究了高炉渣基类水滑石衍生物在CO2吸/脱附过程中的动力学机理.研究表明:准二级动力学模型适用于描述CO2吸附过程,其表观活化能范围为-101.80~-52.91 kJ/mol,吸附过程中的化学吸附为主要控制步骤;CO2脱附过程符合3级Avrami动力学模型,平均表观活化能为150.81 kJ/mol,脱附过程类似于晶体成核过程.本研究旨在明晰类水滑石衍生物在CO2吸/脱附过程中的反应路径与作用机理,为该材料实际工程应用提供理论支持.

Abstract:

The kinetics mechanism of CO2 adsorption/desorption on blast furnace slag-based hydrotalcite derivatives was explored to address the environmental issues caused by CO2 emissions and the overburdened storage of blast furnace slag resources. The results reveal that the Quasi-secondary kinetic model was suitable to describe the CO2 adsorption process, with the apparent activation energy ranging-101.80 to-52.91 kJ/mol. Chemical adsorption was the main controlling step of adsorption process. The desorption process followed the third-order Avrami kinetic model, with an average apparent activation energy of 150.81 kJ/mol, resembling the crystallization nucleation process. This study aimed to clarify the reaction pathway and mechanism of CO2 adsorption/desorption in hydrotalcite-like derivatives and provide theoretical support for the practical engineering application.
