蒸汽活化对天然钙基吸收剂循环碳酸化捕获CO_2的影响
|
摘要
为探明蒸汽活化对钙基CO_2吸收剂活性再生的影响规律,基于热天平系统研究了活化温度、蒸汽浓度、操作频率、碳酸化及蒸汽活化时间以及活化方法对天然钙基吸收剂CO_2捕获性能的影响.结果表明,300~400,℃对天然吸收剂活化效果最优;提高活化水蒸气浓度和频率有利于再生吸收剂碳捕获性能;短时间活化效果低于长时间活化工况;煅烧后水蒸气活化可大幅再生吸收剂活性,而在反应过程中通入蒸汽活化效果不佳;从捕获总量和活化效率考量,高频率短循环方式活化效果更佳.
To study the steam reactivation of natural Ca-based sorbent,the influences of steam hydration temperature,steam concentration,hydration frequency,hydration duration and reactivation strategy on the cyclic carbonation/calcination performance were investigated by using TGA.The results show that the hydration temperature of 300—400,℃ is superior to 500,℃ for natural sorbents reactivation.Carbonation conversion increases with the rise of steam concentration,hydration frequency and hydration duration.Steam hydration after every calcination could regenerate sorbent reactivity more remarkably than steam injection in carbonation and calcination process.Short cycle with high frequency hydration shows the best performance regarding the amount of CO_2 capture and reactivation efficiency.
