Abstract: A method for making a high activity ortho-para hydrogen conversion catalyst is set forth wherein a solution of ruthenium cation is mixed with a solution of a poorly coordinating anion such as aluminate to form a precipitate and the precipitate-containing solution is adjusted to a pH of 7 before recovering the catalyst. A product of this process and a method of using such product is disclosed.

Abstract: One aspect of the invention relates to a catalyst composite containing an extruded catalyst support containing an extruded activated carbonaceous material having specifically a defined pore structure. For example, the extruded activated carbonaceous material may have pores wherein at least about 40% of total Hg porosity occurs in pores having a diameter of about 200 ? and larger. Alternatively the extruded activated carbonaceous material may have a first set of pores having a pore diameter of at least about 40 ? and at most about 100 ? with a porosity of at least about 0.15 cc/g, and a second set of pores having a pore diameter of at least about 5,000 ? and at most about 20,000 ? with a porosity of at least about 0.3 cc/g.

Abstract: The present invention provides a carbon-containing catalyst support that includes at least a carbonaceous material nd a thermosetting or sinterable polymer. The components are mixed and the polymer sintered or thermoset to provide a non-crushable, non-friable, and non-breakable composite. A catalytically active metal can be supported on the carbonaceous material prior to mixing, or on the composite after mixing and heating the mixture to sinter or thermoset the polymer.
