20070203251 - Methods to prepare carbon-isotope labeled organohalides with high specific radioactivity from carbon-isotope monoxide: Methods and reagents for labeling synthesis of organohalides by transition metal mediated carbonylation reactions using carbon-isotope labeled carbon monoxide are provided. The resultant carbon-isotope labeled organohalides are useful as radiopharmaceuticals, especially for use as precursors in Positron Emission Tomography (PET). Associated PET tracers and kits for PET studies are also... Agent: Ge Healthcare, Inc.

20070197667 - Process for separating a catalyst from a liquid: Gaseous reactants (18) are fed into a slurry bed (14) of solid catalyst particles in a liquid. The reactants react as they pass upwardly through the bed, thereby forming liquid and gaseous products. In a primary filtration stage (30), the liquid product passes through a filtering medium having filtering openings,... Agent: Ladas & Parry

20070191498 - Use of a source of chromium with a precipitated catalyst in a fischer-tropsch reaction: According to the present invention there is provided the use of a source of chromium in combination with a precipitated iron catalyst in a high temperature Fischer-Tropsch process to convert CO and H2 to hydrocarbons and possibly oxygenates thereof. In the process CO and H2 are contacted with the source... Agent: Finnegan, Henderson, Farabow, Garrett & Dunner LLP
