Article Preview

ETS-4 with a Si:Ti ratio of 10:1 has been successfully synthesized in our laboratory and its characterization was done using X-ray diffraction (XRD) and scanning electron microscope (SEM). The thermal behavior was studied by thermogravimetric analysis (TGA). The synthesized crystals were pelletized under high pressure without any binder. Thus the pellets have a bidispersed pore structure – intracrystalline macropores and crystal micropores of the order of 0.4 nanometers. Equilibrium isotherms of oxygen, nitrogen and methane on the ETS-4 sample were measured volumetrically. The capacity compares favorably with that of a commercially available adsorbent of similar pore size. Langmuir isotherm fits well to the experimental equilibrium data.
