摘要：

Metal organic framework material, MIL-101(Cr), synthesized by hydrothermal method was granulated using starch and sodium salt of carboxyl methyl cellulose as binder. The equilibrium adsorption capacities of pure gases CO2, N-2, CH4, and CO were measured at 288, 303 and 313 K up to 850 mm Hg on both powder and granules of MIL-101(Cr). The selectivity of CO2 over N-2 in MIL-101(Cr) was found to be 12.6 at 303 K, more than those for CO2 over CH4 (5.69) and CO (2.90). The CO2 dynamic adsorption studies from binary gas mixture (CO2 + N-2) with five different CO2 concentration in the range 5-50 vol.%, and with two different feed gas flow rates (50 and 100 mL/min), were carried out on MIL-101(Cr) granules. The regeneration of adsorbent was feasible at a relatively low temperature attributed to physical adsorption of CO2. The MIL-101(Cr) showed potential for CO2 adsorption compared with different types of carbon, silica and zeolite based adsorbents reported in the literature. (c) 2012 Elsevier B.V.
