TREATMENT OF ALKALI SILICA GEL AND ALKALI POROUS METAL OXIDE COMPOSITIONS

摘要

A method for treating Group 1 metal/silica gel compositions that are pyrophoric is provided to convert them into Group 1 metal/silica gel compositions that are no longer pyrophoric. A method for treating Group 1 metal/porous metal oxide compositions that are pyrophoric is provided to convert them into Group 1 metal/porous metal oxide compositions that are no longer pyrophoric. The pyrophoric Group 1 metal/silica gel composition or the pyrophoric Group 1 metal/porous metal oxide composition is treated with a low amount of dry oxygen or low concentration of dry oxygen mixture to convert them into compositions that are no longer pyrophoric or reactive with dry oxygen or air.
