PFG NMR has been applied to study intracrystalline diffusion in USY zeolite as well as in the parent ammonium-ion exchanged zeolite Y used to produce the USY by zeolite steaming. The diffusion studies have been performed for a broad range of molecula

Diffusivities of n-octane in particles of industrial fluid catalytic cracking (FCC) catalysts and in zeolite USY, which is the main zeolitic component of the particles, are reported. Diffusion measurements have been performed by using pulsed field gr

The electronic conductivity of some Sr- and Mg-doped lanthanum gallates was measured as a function of the oxygen activity in the p O 2 range of about 10 1 –10 −17 bar using the Hebb–Wagner polarization technique. The investigated compositions w

One method that has been considered for storage of hydrogen as a fuel onboard of vehicles is its adsorption in the voids of porous solids. Zeolites are among the classes of microporous materials that have been extensively studied for this purpose. Ph
