Abstract: A process for reducing total acid number (TAN), comprising: contacting, without hydrogen addition, a liquid hydrocarbon having a high initial TAN with a ternary catalyst comprising titanium-oxide, a metal promoter, and a porous support; wherein the contacting occurs over a short time or at a defined LHSV, and at a low contacting temperature, and wherein the contacting reduces the initial TAN by at least 20%. Also, a new ternary catalyst that reduces the TAN, wherein the ternary catalyst has a molar ratio of titanium to metal from the metal promoter that is greater than 3:1.
