Document Type and Number:

Japanese Patent JP2006511334

Kind Code:

A

Abstract:

A method for regenerating spent supported metal catalysts comprising treating the spent catalyst with an organo-metallic complex forming agent having an ionization constant pK₁of at least 2.5. The catalyst activity is restored to an activity level near to or greater than the fresh catalyst. The regeneration method is particularly useful for regenerating spent palladium catalysts on an alumina support as utilized for the hydrogenation of ethyl anthraquinone (EAQ) in the production of hydrogen peroxide.
