标 题 :Process for regenerating noble metal catalyst for the synthesis of hydrogen peroxide according to the anthraquinone process
发明人：SCHREYER GERD; THEISSEN FERDINAND; WEIBERG OTTO; WEIGERT WOLFGANG
权利人:DEGUSSA
摘要:In situ regeneration of noble metal catalysts for the synthesis of hydrogen peroxide by the anthraquinone process is provided by employing as the working solution coming from the extraction or desorption step and being introduced into the hydrogenation step a solution which contains at least 250 mg/liter of hydrogen peroxide, to thereby completely regenerate the noble metal catalyst by full capacity of the hydrogenation step.
