Abstract:

In recent years,excessive emission of carbon dioxide(CO2) and other greenhouse gases has increasingly become a serious global issue of climate change.In order to achieve the goal of“Carbon peak and carbon neutralization”,China actively participates in the carbon emission reduction in the world and closely follows the global trend of green and low-carbon development.China is in the transitional period from the old to the new energy structure,the most important source of carbon dioxide is the flue gas emission from fossil fuel fired thermal power plants.Therefore,it is still the key concern by reducing the flue gas emissions.Using ammonia method to capture carbon in carbon capture and storage(CCS) has become one of the current research highlights with many advantages.By analogying the effect of additives on the inhibition of ammonia escape and CO2 removal effect during the ammonia absorption,the effect of inorganic additives on the desorption of rich liquid in regeneration was mainly analyzed,the research progress at home and abroad was reviewed,and the future development direction of this technology was prospected,including the regeneration mechanism,regeneration energy consumption,ammonia escape,recycling of additives and absorbents,and the attempts of transition metal oxides in the process,etc.

Key words: ammonia decarbonization, regeneration process, CO2, ammonia escape, inorganic additives
