Abstract

A useful partial oxidation catalyst element includes a catalyst component, a support component, and a substrate. The catalyst component is formed by combining a catalytically active metal with a first support material to form a mixture and calcining the mixture. The support component is formed by calcining a second support material, not containing the active metal. The first and second support materials include particles having an average particle diameter of less than 20 microns. A catalyst material is formed by combining the catalyst component and the support component, wherein the catalyst material contains less than 20% of the catalyst component by weight. The catalyst material is applied to a substrate configured for gas flow therethrough, thereby formulating the partial oxidation catalyst element. The partial oxidation catalyst element is especially useful for fuel reforming and fuel cell applications.

Method of treating intermetallic alloy hydrogenation/oxidation catalysts for improved impurity poisoning resistance, regeneration and increased activity

Patent Wright, Randy B [Idaho Falls, ID]

Alternate, successive high temperature oxidation and reduction treatments, in either order, of intermetallic alloy hydrogenation and intermetallic alloy oxidation catalysts unexpectedly improves the impurity poisoning resistance, regeneration capacity and/or activity of the catalysts. The particular alloy, and the final high temperature treatment given alloy (oxidation or reduction) will be chosen to correspond to the function of the catalyst (oxidation or hydrogenation).

Cobalt Fischer-Tropsch catalysts having improved selectivity

Patent Miller, James G [Pearl River, NY]; Rabo, Jule A [Armonk, NY]

The promoter(s) Mn oxide or Mn oxide and Zr oxide are added to a cobalt Fischer-Tropsch catalyst combined with the molecular sieve TC-103 or TC-123 such that the resultant catalyst demonstrates improved product selectivity, stability and catalyst life. The improved selectivity is evidenced by lower methane production, higher C5+ yield and increased olefin production.
