Abstract: The present disclosure provides systems and methods for producing a regenerated hydrogenation catalyst used for hydrogenating a biomass feedstock. The method can include a regeneration cycle, in which a fouled hydrogenation catalyst is contacted with (a) a first flushing medium comprising water and a gaseous phase comprising oxygen and (b) a second flushing medium comprising water and a gaseous phase comprising at least 90% nitrogen by volume. In particular, multiple regeneration cycles can be used to improve efficiency in removing sulfur-containing impurities from the fouled catalyst.
