Abstract
copper benzene-1, 3, 5-tricarboxylate (Cu-BTC) metal organic framework is a promising material for CH4 storage. However, the shortcomings of high adsorption heat and low thermal conductivity restrict the industry application of the Cu-BTC material. A new hierarchical pores material of Cu-BTC/CuO/Carbon fiber paper (Cu-BTC/CuO/CFP) is synthesized to improve the thermal conductivity and gas separation of Cu-BTC. The results show that the thermal conductivity of the hierarchical pores material is 17.64 times higher compared to that of pure Cu-BTC. The selectivity of equimolar CH4/H2 in Cu-BTC/CuO/CFP is similar to that of pure Cu-BTC, while the selectivity of equimolar CH4/N2 in Cu-BTC/CuO/CFP is 2.15~2.65 times higher compared to that of pure Cu-BTC at pressure range from 0 to 100 kPa and 0°C.
