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.
