A process useful for treating biologically derived oils in the production of biofuels is described. A biologically derived oil feed is deoxygenated by contacting the feed with a metal titanate catalyst comprising a metal titanate having an MTiOperovskite structure wherein M is a metal having a valence of 2+. The process does not require the addition of hydrogen.

A synthesis gas conversion process for carrying out the process is disclosed. A hydrogen-containing sweep gas is caused to flow across a water permselective membrane adjacent a synthesis gas conversion reaction zone in which synthesis gas is contacted with a catalyst and converted to effluent including water. Water is removed from the reaction zone through the membrane. The sweep gas has sufficient hydrogen partial pressure to cause hydrogen to pass through the membrane into the reaction zone.

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.

An energy-efficient process for dewatering an aqueous organic solution includes using freely available solar energy to concentrate a draw solution within a reservoir. The draw solution is used in conjunction with a membrane to remove water from the organic solution in a forward osmosis process. The draw solution is diluted by the osmosis process, and returned to the reservoir to be re-concentrated and reused in the osmosis process.

Disclosed are embodiments relating to a process for reducing the total acid number of a hydrocarbon feed by contacting the feed with a metal titanate catalyst having an MTiOstructure wherein M is a metal having a valence of 2+, resulting in a hydrocarbon product having a final total acid number lower than the initial total acid number of the feed. The process is useful for pretreating high acid crudes prior to further processing thus avoiding corrosion of equipment used in refining operations. The process can be integrated into conventional refining operations in order to treat various refinery streams. In one embodiment, a process is provided for refining a low acid crude oil and a high acid crude oil by separately introducing a relatively low acid crude oil feed and a relatively high acid crude oil feed to an atmospheric distillation column, wherein the relatively high acid crude oil feed is contacted with a metal titanate catalyst prior to introduction to the atmospheric distillation column.

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.
