THE ROLE OF ADSORPTION IN THE CATALYTIC PARA-ORTHO-HYDROGEN CONVERSION

Abstract

Adsorption isotherms were determined for two para-ortho-hydrogen conversion catalysts, hydrous ferric oxide gel and nickel oxide silicate, at temperatures from 63K to 196K and at pressures from 1 to 10 atmospheres. For the catalysts studied, Langmuir's Isotherm holds at 194.6K, while at lower temperatures (approximately 60-90 K), the adsorption mechanism appears to be one where two molecules are adsorbed on five effective centers.
