RECOVERY OF RHENIUM FROM A CATALYST SUPPORT |
摘要 |
<p>The present invention relates to a method for recovering rhenium from an ethylene oxide catalyst containing rhenium and at least silver on a solid support, wherein at least a substantial portion of the rhenium present in the catalyst is extracted by intimate contact of the catalyst with one or more polar non-acidic organic solvents substantially free of water such that a rhenium-containing solution is formed containing the polar non-acidic organic solvent and extracted rhenium, the polar non-acidic organic solvent containing one or more oxygen, nitrogen, and/or halogen atoms in its molecular structure.</p> |
