20080307779 | Regenerable sulfur traps for on-board vehicle applications - Provided are improved regenerable SO | 12-18-2008 |
20100022670 | Preparation of high activity cobalt catalysts, the catalysts and their use - A method is provided for preparing a supported cobalt-containing catalyst having substantially homogenously dispersed, small cobalt crystallites. The method comprises depositing cobalt nitrate on a support and then heating the support in an oxygen-containing, substantially water-free atmosphere to about 160° C. to form an intermediate decomposition product. This intermediate decomposition product is then calcined and reduced. | 01-28-2010 |
20120083410 | 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. | 04-05-2012 |
