Abstract: A crude oil which contains at least 0.1 wt % unstable sulfur compounds is treated in a reaction zone at low temperature to convert at least 50 wt % of the unstable sulfur compounds contained therein. The reaction and removal of sulfur from the crude may be facilitated by contacting the crude oil with a catalytic material in the presence of a stripping fluid.

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.
