• Titanosilicate has unique properties in adsorptive separations such as air separations. In this study, Ag-ETS-10 was investigated for argon free oxygen production. During laboratory scale breakthrough experiments high purity (99.7+%) oxygen was produced at 100 kPa and 25 °C, with a recovery rate greater than 30%. These results suggest that Ag-ETS-10 could be a strong adsorbent candidate for generating high purity O2 in PSA.
  Furthermore, the kinetics of Na-ETS-10 was investigated using breakthrough experiments. A breakthrough concentration profile of diluted (5+%) methane balance helium was obtained at 100 kPa and 25 oC and was fitted with Aspen adsorption simulator. The macro/ micropore mass transfer coefficients as the adjustable tuning parameters were estimated to be 261.76 (in 1/s) and 6121.87 (in 1/s), respectively. These results are very promising as they suggest the current particles are sufficiently “fast” to be used in an adsorption process near the fluidization limit of the particles.
