Abstract
The invention relates to a novel mixed ion and electron conducting catalytic ceramic membrane and to its use in hydrocarbon oxidation and or dehydrogenation processes, the membrane consists of two layers, layer 1 which is an impervious mixed ion and electron conducting ceramic layer and layer 2 which is a porous catalyst-containing ion conducting ceramic layer.
Claims9
A ceramic membrane structure comprised of a first layer which is a mixed oxygen ion and electron conducting impervious ceramic layer and a second layer which is associated with said first layer and which is a catalyst-containing porous ion conducting ceramic layer.
A ceramic membrane structure comprised of first layer which is mixed oxygen ion and electron conducting impervious stabilized zirconia ceramic doped with a Group-VB, VIB or titanium oxide, and a second layer which is associated with said first layer and which is a porous, catalyst-containing, stabilized zirconia ceramic layer.
A ceramic membrane structure comprised of a first layer which is a mixed oxygen ion and electron conducting impervious ceramic layer comprised of about 77-88 mole % zirconia, about 10-13 mole % yttria, and about 1-10 mole % titania, and a second layer which is associated with said first layer and which is a catalyst-containing porous ceramic layer.
A ceramic membrane structure comprised of a first layer which is a mixed oxygen ion and electron conducting impervious ceramic layer and a second layer which is associated with said first layer and which is a catalyst-containing porous ceramic layer comprised of zirconia stabilized with about 8 to 15 mole % calcia, yttria, scandia, magnesia and/or mixtures thereof.
