Copper (II) carboxylate, (Cu-BDC), metal-organic-framework (MOF) has been synthesized
undersolvothermalconditions and used as a new adsorbent for the methane. The Lithium
doping intoCu-BDC, (Li-Cu-BDC), is made by impregnating Cu-BDC with an ethanol solution
ofLiNO3, followed by heat treatment in vacuum. The adsorbent was characterized by X-ray
diffraction (XRD), Fourier transform infrared (FT-IR), Thermogravimetric analysis (TGA).
Inductively coupled plasma atomic emission spectrometry (ICP-AES) and Brunauer-Emmet-
Teller (BET) technique. The Sorption capacity of the methane on Cu-BDC and Li-Cu-BDC
range of pressure 1-20 bar and at 298 K was investigated by volumetric measurement. This
work shows that Li-Cu-BDCCompared with Cu-BDC has higher sorption capacity for CH4.
