Abstract
The present disclosure is directed to a non-destructive process for removing metals, metal ions and metal oxides in alumina-based materials without destroying alumina, allowing the regeneration of alumina-based catalysts. The non-destructive process uses an extracting agent that sequesters metals, metal ions and/or metal oxides present in alumina-based materials without destroying the alumina, allowing the regeneration of alumina-based catalysts.
