Difference between base promoted-promoted and base catalysed-catalysed

Why is halogenation of ketones in a base isdescribed as being "base promoted"-promoted" and not "base catalysed" -catalysed"?

I seek an answer with reference to the specific step in the mechanism , ifIf the reaction is not "catalyzed" then how is the given base used up  ?
