Efficient separation of C4 olefins using tantalum pentafluor oxide anion-pillared hybrid microporous material
文献摘要：
With the increasing demand for synthetic rubber,the purification of 1,3-butadiene(C4H6)is of great industrial significance.Herein,the successful removal of n-butene(n-C4H8)and iso-butene(iso-C4H8)from 1,3-butadiene(C4H6)was realized by synthesizing a novel TaOF52-anion-pillared ultramicroporous material TaOFFIVE-3-Ni(also referred to as ZU-96,TaOFFIVE=TaOF5-,3=pyrazine).Single-component adsorption isotherms show that TaOFFIVE-3-Ni can achieve the exclusion of n-C4H8 and iso-C4H8 in the low pressure region(0-30 kPa),and uptake C4H6 with a high capacity of 92.78 cm3·cm-3(298 K and 100 kPa).The uptake ratio of C4H6/iso-C4H8 on TaOFFIVE-3-Ni was 20.83(298 K and 100 kPa),which was the highest among the state-of-the-art adsorbents reported so far.With the rotation of anion and pyrazine ring,the pore size changes continuously,which makes smaller-size C4H6 enter the channel while larger-size n-C4H8 and iso-C4H8 are completely blocked.The excellent breakthrough performance of TaOFFIVE-3-Ni shows great potential in industrial separation of C4 olefins.The specific adsorption binding sites within ZU-96 was further revealed through the modeling calculation.
