Research progress in piperazine and its derivatives as carbon dioxide absorbent
The reaction mechanism of piperazine with CO2 is introduced.The advantages and disadvantages of single component piperazine derivatives,mixed amines solution absorbent with piperazine-containing organic amines,mixed absorbers with piperazine-containing organic amines and inorganic solvents,and piperazine-modified solid adsorbents for CO2 capture are summarized.The study on CO2 capture by piperazine derivative absorbers is also proposed.
