Zusammenfassung:	THE INVENTION COMPRISES A METHOD FOR REDUCING THE AMOUNT OF CARBOXYLIC ACIDS IN PETROLEUM FEEDS COMPRISING THE STEPS OF (A) ADDING TO SAID PETROLEUM FEED A CATALYTIC AGENT COMPRISING AN OIL SOLUBLE OR OIL DISPERSIBLE COMPOUND OF A METAL SELECTED FROM THE GROUP CONSISTING OF GROUP VB, VIB, VIIB AND VIII METALS, WHEREIN THE AMOUNT OF METAL IN SAID PETROLEUM FEED IS AT LEAST ABOUT 5 WPPM, (B) HEATING SAID PETROLEUM FEED WITH SAID CATALYTIC AGENT IN A REACTOR AT A TEMPERATURE OF ABOUT 204.44 TO ABOUT 426.67°C. (ABOUT 400 TO ABOUT 800°F.), UNDER A HYDROGEN PRESSURE OF 204.75 TO 6996.33 KPA (15 PSIG TO 1000 PSIG ), AND (C) SWEEPING THE REACTOR CONTAINING SAID PETROLEUM FEED AND SAID CATALYTIC AGENT WITH HYDROGEN-CONTAINING GAS AT A RATE SUFFICIENT TO MAINTAIN THE COMBINED WATER AND CARBON DIOXIDE PARTIAL PRESSURE BELOW ABOUT 344.75 KPA (ABOUT 50 PSIA).
