20100022388 | Preparation of high activity cobalt catalysts, the catalysts and their use - A method is provided for preparing a supported cobalt-containing catalyst having substantially homogeneously dispersed, small cobalt crystallites. The method comprises depositing cobalt nitrate on a support and then subjecting the support to a two-step decomposition protocol. In the first step, the support is heated in an oxygen-containing, substantially water-free atmosphere to about 160° C. to form an intermediate decomposition product. This intermediate product is then or hydrolyzed and reduced, or hydrolyzed, calcined and reduced. | 01-28-2010 |

20100184895 | Hydrogenation Processes - The present invention is directed to a process for hydrogenating one or more organic compounds especially unsaturated organic compounds by bringing the compound into contact with a hydrogen-containing gas in the presence of a catalyst, which comprises one or more catalytically active metals applied to a porous catalyst support. The one or more catalytically active metals having been derived via a decomposed organic complex of the metal on the support, in particular amine complexes of the metal. The decomposed complex may be treated with hydrogen to activate the catalyst before use as a hydrogenation catalyst. | 07-22-2010 |

20120227584 | AGGREGATES OF SMALL PARTICLES OF SYNTHETIC FAUJASITE ZEOLITE - This invention relates to aggregates of small particles of synthetic faujasite zeolite. Small primary particles of zeolite are clustered into larger secondary particles. The observable average width of the primary particles may be 0.3 micron or less and the observable average width of the secondary particles may be 0.8 micron or more. The silica to alumina ratio of the zeolite may be less than 4:1. | 09-13-2012 |
20120271076 | Iridium-Containing Catalysts, Their Production and Use - A process is described for producing a catalyst composition comprising an iridium component dispersed on a support. In the process, silica-containing support is treated with an iridium compound and an organic compound comprising an amino group to form an organic iridium complex on the support. The treated support is then heated in an oxidizing atmosphere at a temperature of about 325° C. to about 475° C. to partially decompose the organic metal complex on the support. The treated support is then heated in a reducing atmosphere at a temperature of about 350° C. to about 500° C. to convert the partially decomposed organic iridium complex into the desired iridium component. | 10-25-2012 |
20120271077 | Dehydrogenation Process - In a dehydrogenation process a hydrocarbon stream comprising at least one non-aromatic six-membered ring compound and at least one five-membered ring compound is contacted with a dehydrogenation catalyst produced by a method comprising treating the support with a liquid composition comprising the dehydrogenation component or a precursor thereof and at least one organic dispersant selected from an amino alcohol and an amino acid. The contacting is conducted under conditions effective to convert at least a portion of the at least one non-aromatic six-membered ring compound in the hydrocarbon stream to benzene and to convert at least a portion of the at least one five-membered ring compound in the hydrocarbon stream to paraffins. | 10-25-2012 |
