Document Type and Number:
WIPO Patent Application WO/1997/016249
Kind Code:
A1
Abstract:
A method for reactivating a ruthenium catalyst, comprising the steps of bringing a ruthenium catalyst whose activity has been reduced due to the use in the hydrogenation of unsaturated organic compounds into contact with oxygen in a liquid phase, and holding the catalyst under a lower partial pressure of hydrogen than that in the hydrogenation and at a temperature which is not lower than the hydrogenation temperature minus 50 �C.
