Porous alumina tube externally coated with a MgO/PbO dense film (in double pipe configuration), tube thickness 2.5 mm, outer diameter 4 mm, mean pore diameter 50 nm, active film-coated length 30 mm. Feed enters the reactor at shell side, oxygen at tube side. Oxidative methane coupling, PbO/MgO catalyst in thin film form (see previous column). r-750X,Pr ed 1 bar. Conversion of methane <2%. Selectivity to Cj products > 97%. Omata et al. (1989). The methane conversion is not given. Reported results are calculated from permeability data. [Pg.140]

Fig. 8.2 Oxygen tracer diffusivities and oxygen permeabilities through liquid boron oxide, fused silica, and a polycrystalline alumina with a grain size of 5 nm. Tracer diffusivity values for B203 and Si02 were obtained from Refs. 9 and 19, respectively. Tracer diffusivity values for A1203 were obtained from data reported in Ref. 18 using a grain size of 5 /im (Ref. 13). Oxygen permeability constants were obtained using the procedure outlined in the text.2...

In this section, a brief overview is given of major membrane concepts and materials. Besides membranes made from a mixed ionic-electronic conductor (MIEC), other membranes incorporating an oxygen ion conductor are briefly discussed. Data from oxygen permeability measurements on selected membrane materials are presented. [Pg.436]

At 1000°C, significant levels of electronic conduction in titania-doped YSZ, as in ceria-doped specimens, are foimd only under strongly reducing atmospheres. Data of oxygen permeability have been presented for the Zr02-Y203-Ti02 system by Arashi and Naito [127] (see also Table 10.1). By virtue of its... [Pg.477]
