摘要： The present invention relates to a method of regenerating a ruthenium catalyst suitable for hydrogenation, which comprises flushing the catalyst with inert gas in a regeneration step until the original activity or part of the original activity has been attained. The method is particularly useful for ruthenium catalysts which are used for the hydrogenation of aromatics.
