Catalyst configuration and methods for syngas production

A catalyst composition comprises at least one first layer of a catalytically active metal dispersed on an inert carrier first support and at least one second layer of a reduced metal catalyst consisting essentially of a noble or transition metal supported on or in a stable inorganic metal oxide wash...

Zusammenfassung:A catalyst composition comprises at least one first layer of a catalytically active metal dispersed on an inert carrier first support and at least one second layer of a reduced metal catalyst consisting essentially of a noble or transition metal supported on or in a stable inorganic metal oxide washcoat on a second support, the first layer having a greater thermal stability than the second layer. The catalyst compositions may be used to catalyse the partial oxidation of hydrocarbons, particularly C1 to C4 hydrocarbons, to form synthesis gas mixtures of carbon monoxide and hydrogen. The first layer may, for example, comprise rhodium supported on alumina. The second layer may comprise a porous partially stabilised zirconia monolith having a ceria wash coat supporting a rhodium metal catalyst.
