MgO基CO2吸附剂成型技术研究进展
Research progress on granulation technologies of MgO-based CO2 adsorbent
摘要
Abstract
Carbon capture,utilization and storage(CCUS)technology is an effective way to mitigate the greenhouse effect.Using solid adsorbents to capture CO2 is considered to be one of reliable ways of reducing CO2 emissions.MgO-based adsorbents have attracted much attention due to their wide source,low regeneration temperature and high theoretical adsorption capacity in various solid adsorbents.However,the formed MgO-based adsorbents still face the problems of low mechanical strength,poor stability and easy to escape from the reactor,so they are difficult to be widely used in industry.The effects of different granulation methods and granulation process conditions on the CO2 adsorption performance of MgO-based adsorbents were summarized.In the granulation process,the MgO-based adsorbents with smaller particle sizes have faster carbonation rates and lower wear rates.The chemical properties and mechanical strength of adsorbent particles can be improved by adding proper amount of granulation additives and steam.However,higher calcination temperatures can exacerbate sintering and wear of absorbent particles.In the future,the research should focus on developing simplified processes,low costs and good cycle stability,and prepare absorbent particles with both excellent CO2 adsorption performance and mechanical properties for industrial-scale CO2 capture.关键词
