Document Type and Number:
WIPO Patent Application WO/2003/033431
Kind Code:
A1
Abstract:
A porcelain composition comprising an oxide ion mixed conductor having a perovskite crystal structure containing Ba, at least one element selected from Co and Fe, and at least one element selected from among In, Sn and Y&semi a catalyst and ceramic composite material which comprises a selective oxygen−permeable dense continuous layer, a porous intermediate catalyst layer being adjacent to a first surface of the oxygen−permeable layer, a porous catalyst layer containing a mixedly electroconductive oxide layer and being adjacent to a second surface of the oxygen−permeable layer, and a porous reaction catalyst layer containing a metal catalyst and a catalyst carrier being adjacent to the porous intermediate catalyst layer&semi a catalyst and ceramic composite material which comprises a dense ceramic film containing an oxide ion−electron mixedly electroconductive oxide having a perovskite crystal structure and, formed on the surface thereof, a (reforming) catalyst sector containing magnecia and Ni (and optionally Mn)&semi and, a film reactor, an apparatus for producing a synthetic gas, and a method for activating a catalyst which use these composite materials.
