Abstract
A process is described for reducing the total acid number of a refinery feedstock. A refinery feedstock containing naphthenic acids is contacted with an effective amount of solid catalyst that has been pretreated with an aqueous caustic base, for a period of time sufficient to neutralize at least a portion of the naphthenic acids in the feedstock. Thereafter, the aqueous phase is separated from the neutralized refinery feedstock.
