National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

The Role of Adsorption in the Catalytic Para-Ortho-Hydrogen Conversion.

AD814417

Publication Date	1967
Personal Author	Lander, H. R.
Page Count	35
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.
