The present invention provides a method and composition regeneration of an aminal that has previously been reacted with a sulfide selected from hydrogen sulfide and mercaptans. The method includes contacting a scavenging mixture which includes an aminal, and an oxidation catalyst with a gas such as air, oxygen enriched air, oxygen, ozone enriched air and ozone. The composition includes an aminal, and an oxidation catalyst. The method and composition are useful for the regeneration of an aminal base sulfur scavenging compound.

La présente invention concerne un procédé et une composition permettant la régénération d'un aminal qui a été mis à réagir précédemment avec un sulfure choisi parmi des hydrogènes sulfurés et des thiols. Le procédé consiste à mettre en contact un mélange d'épuration comprenant un aminal et un catalyseur d'oxydation avec un gaz tel que de l'air, de l'air enrichi d'oxygène, de l'oxygène, de l'air enrichi d'ozone et de l'ozone. La composition de la présente invention comprend un aminal et un catalyseur d'oxydation. Le procédé et la composition sont utilisés pour la régénération d'un composé d'élimination du soufre à base d'aminal.
