WebAdsorption isotherms of pure C2H4 and C3H6 were measured on 11 adsorbents and at pressures up to 0.8 MPa using a volumetric method. The Brunauer–Emmett–Teller (BET) surface area of the adsorbents had a significant effect on adsorption capacities of both C2H4 and C3H6. The metal organic framework MIL-101 had the highest BET surface … WebFeb 28, 2007 · (B) Adsorption positions are classified into three positions: (a) metal site, (b) carboxylato site and (c) ring site. 2.3.
