Abstract

An investigation is performed of the patterns of CO₂ chemisorption by the carbon dioxide sorbent Dräger 800+. The dynamics of changes in textural characteristics, phase, and chemical compositions of the material in the process of chemisorption at the level of individual sorbent granules are studied. The dependence of the period of the protective action of the sorbent on the height of its layer, and on the flow rate and concentration of carbon dioxide in the initial gas–air mixture is determined. Based on experimental data, an empirical equation is obtained that can be used to predict the period of protection by a layer of granules of Dräger 800+ absorber at known contact time and concentrations of carbon dioxide in the gas mixture.

流动吸附器中含钙吸附剂的 CO2 吸收模式

摘要

对二氧化碳吸附剂 Dräger 800+的 CO ₂化学吸附模式进行了调查。研究了在单个吸附剂颗粒水平的化学吸附过程中材料的结构特征、相和化学成分变化的动力学。吸附剂的保护作用时间与其层的高度以及初始气体-空气混合物中二氧化碳的流速和浓度的关系被确定。根据实验数据，获得了一个经验方程，可用于预测在已知接触时间和气体混合物中二氧化碳浓度下，一层 Dräger 800+ 吸收剂颗粒的保护期。
