ABSTRACT:
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.
