ملخص المقالة :
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.
