Particulate solids for catalyst supports and heat transfer materials

Abstract From the Canadian patent

A particulate, precalcined low silica content zirconia especially one stabilized with yttria, is useful as a catalyst support or as a heat transfer solids component for conducting chemical reactions at high temperature, in oxidizing reducing or hydrothermal, conditions, especially in syn gas operations. An admixture of precalcined particulate low silica content zirconia particularly a low, silica content yttria-stabilized zirconia is employed in a preferred, embodiment as a heat transfer solid in concentrations ranging, generally from about 10 wt% to about 99.9 wt% with a particulate, catalyst, notably a nickel-on-alumina catalyst in concentration, ranging generally from about 0.1 wt% to …
