As powerful and effective supplement to conventional natural gas in future
the unconventional gas including low concentration coalbed methane and biomass need to remove a large amount of N2 and CO2 to achieve enrichment and purification of CH4. To separate N2 and O2
Cu(INA)2 with pores of a one-dimensional rhombus was chosen as an adsorbent. The synthesized sample was characterized with XRD and TG. Combined with CO2
CH4 and N2 adsorption curves
the grand canonical ensemble Monte Carlo (GCMC) molecular modeling and the ideal adsorbed solution theory (IAST) were used to calculate the adsorption heat of gas and adsorption selectivities for binary mixtures (CH4/N2 and CO2/CH4)
separately; For breakthrough separation experiments
powder samples of Cu(INA)2 were pelletized into particles of a certain size under pressure of 3 MPa. The result revealed that Cu(INA)2 has not only high selective adsorption of CH4 in mixture of CH4/N2 (SCH4/N2=10)
but also better separation for CH4/N2 than CO2/CH4.
