| 20090159504 | PROCESS TO REDUCE ACIDITY OF CRUDE OIL - A process to reduce the acidity of acidic crude oils for preventing corrosion during processing of the crude oils, including transferring through pipe lines, tanker ships and tank vehicles. Crude oil having substantial amount of organic acid, in particular, naphthenic acid compounds is contacted with supercritical water and a catalyst for deacidification. A treated crude oil product has lower amounts of organic acid compounds than the original crude oil. | 06-25-2009 |

| 20090230026 | Catalyst To Attain Low Sulfur Gasoline - This invention relates to a hydrodesulfurization catalyst, a method for preparing the catalyst, and a method for the preparation of low sulfur gasoline fuel with minimal loss of RON. The catalyst particles include a group VIB metal and a support material having relatively high surface area, and optionally includes one or more group VIIIB metal. The method for preparing the catalyst allows for greater loading of the active metal species on the surface of the support material under aqueous reaction conditions. | 09-17-2009 |

| 20090145807 | PROCESS TO PRODUCE LOW SULFUR CATALYTICALLY CRACKED GASOLINE WITHOUT SATURATION OF OLEFINIC COMPOUNDS - The invention relates to a process for the desulfurization of a gasoline fraction with high recovery of olefins and reduced loss of Research Octane Number (RON). A petroleum fraction is contacted with hydrogen and a commercially available hydrodesulfurization catalyst under mild conditions with to remove a first portion of the sulfur present, and is then contacted with an adsorbent for the removal of additional sulfur. | 06-11-2009 |
