The process is based on the discovery that deactivating contaminants present in typical hydrocarbon feeds, such as chlorides, can be removed with an alumina guard bed prior ... 11/16/06 - 20060258530 - Prox catalyst for oxidizing carbon monoxide A catalyst for preferentially reducing carbon monoxide in a hydrogen stream. The catalyst is formed from a chemical composition including a hexaaluminate, a metal hydroxide and a precious metal. The composition may be disposed on a support or may be extruded or cast into or onto a support. Incorporation of ... 02/16/06 - 20060035783 - Fluid/slurry bed cobalt-alumina catalyst made by compounding and spray drying A method for producing a cobalt on alumina catalyst is disclosed. The catalyst is prepared by thoroughly mixing cobalt nitrate into a peptized alumina slurry, and then spray-drying the slurry to form attrition resistant microspheres. The cobalt prepared by this invention is fully reducible. Optionally, metals such as ruthenium can ... 01/26/06 - 20060019826 - Selectively suppressing catalytic hydrogenation The hydrogenation activity of a heteroatom removal catalyst, having activity for both heteroatom removal and hydrogenation, is selectively suppressed by a treatment which comprises contacting the catalyst with (i) hydrogen, (ii) a selectively deactivating agent that suppresses the catalyst's hydrogenation activity, and (iii) a protective agent, such as CO, that ... 12/01/05 - 20050266987 - Catalysts with high cobalt surface area A catalyst or precursor thereto comprising cobalt and/or a cobalt compound on a transition alumina support having a total cobalt content of at least 41% by weight and a cobalt surface area, after reduction, greater than 25 m2 per gram of total cobalt. The catalyst or precursor may be made ... 09/29/05 - 20050215429 - Catalyst powder, exhaust gas purifying catalyst, and method of producing the catalyst powder A method of producing catalyst powder of the present invention has a step of precipitating a transition metal particle and a base-metal compound in a reversed micelle substantially simultaneously, and a step of precipitating a noble metal particle in the reversed micelle. By this method, it is possible to obtain ... ### FreshPatents.com Support |
