OXIDATIVE DEHYDROGENATION OF PROPANE ON CATALYTIC MEMBRANE REACTORS

The oxidative dehydrogenation of propane (ODHP) has been studied in a catalytic membrane reactor using either an ODHP catalyst (V-Mg-O or Ni based) supported on commercial porous alumina membranes, or a V-Mg-O catalyst bed enclosed in a zeolite membrane. No significant membrane e ffects were found on the macro-and mesoporous V-Mg-O and Ni membranes. In contrast, the zeolite microporous membrane revealed to be an effec tive gas barrier, allowing a marked increase in propene yields at low C3H8/O-2 ratios under separate feeding configuration.
