Abstract: A method for forming a supported metal-containing powder. The method comprises forming a dispersion of a particulate support in a solution, which comprises a solvent and a dissolved metal. Heat is removed from the dispersion to precipitate the dissolved metal from the solution onto the particulate support. Preferably, enough heat is removed to freeze the solution. Also, the heat is removed is preferably removed from the dispersion by contacting a container containing the dispersion with a cryogenic liquid. After precipitating the dissolved metal onto the particulate support, the particulate support is separated from the solution, preferably by freeze-drying, to yield the supported metal-containing powder, which comprises the particulate support and a precipitated metal thereon.

Abstract: The present invention relates to improved catalyst compositions, as well as methods of making and using such compositions to prepare synthesis gas and ultimately C5null hydrocarbons. In particular, preferred embodiments of the present invention comprise catalyst systems comprising a core and an outer region disposed on said core, wherein a substantial amount of the catalytic metal is located in the outer region of the catalyst support matrix. In addition, the catalyst systems are able to maintain high conversion and selectivity values with very low catalytically active metal loadings. The catalyst systems are appropriate for improved syngas, oxidative dehydrogenation and other partial oxidation reactions, including improved reaction schemes for the conversion of hydrocarbon gas to C5null hydrocarbons.
