Activity, Surface Area, and Weight Loss Correlations for Hydrous Ferric Oxide Catalyst
The hydrous ferric oxide (Fe2O3 · xH2O) catalyst developed by Loebenstein and Weitzel has been shown to be quite effective for ortho-para hydrogen conversion. The desire to obtain maximum activity for the hydrous ferric oxide catalyst has led to various activation procedures by previous investigators[2,3,4]. These methods consisted of holding the catalyst at an elevated temperature while either pumping to a moderate vacuum or purging with a pure gas for some specified length of time.
