PROCESS FOR THE REGENERATION OF USED CATALYST IN THE MANUFACTURE OF HYDROGEN PEROXIDE BY THE ANTHRAQUINON PROCESS, AN APPARATUS THEREFOR AND HYDROGEN PEROXIDE MANUFACTURED APPLYING THIS REGENERATION PROCESS.

摘要

Process for the regeneration of catalysts employed in the production of hydrogen peroxide by the anthroquinon process using carrier based catalysts in the hydrogenation stage thereof characterized in that the catalyst which has become inactive due to successive operation is regenerated by a preliminary treatment to remove adhering impurities followed by first an oxidative treatment at pH values below 7 and then a reductive treatment at temperatures below 200C.
