20100029474 | Hydrotreating catalyst system suitable for use in hydrotreating hydrocarbonaceous feedstreams - A stacked bed catalyst system comprising at least one first catalyst selected from conventional hydrotreating catalyst having an average pore diameter of greater than about 10 nm and at least one second catalyst comprising a bulk metal hydrotreating catalyst comprised of at least one Group VIII non-noble metal and at least one Group VIB metal and optionally a binder material. | 02-04-2010 |
20110172089 | PROCESS FOR PRODUCING LOWER-HYDROCARBON AROMATIZATION CATALYST AND LOWER-HYDROCARBON AROMATIZATION CATALYST - [Task] To improve activity of a lower hydrocarbon aromatization catalyst and the catalyst stability. | 07-14-2011 |
20130225400 | METHOD FOR PREPARING HYDROREFINING CATALYST - A method for preparing hydrorefining catalyst comprises the following steps: (1) mixing an aqueous ammonia solution with a polyamine complexing agent to form a mixed solvent; (2) adding a cobalt salt to the mixed solvent, dissolving the cobalt salt, and then adding a molybdenum salt and optional salts of other active components, and dissolving them to prepare an impregnating solution; and (3) impregnating a support with the impregnating solution, followed by aging, drying, and activating the impregnated support to form a hydrorefining catalyst. The hydrorefining catalyst prepared by this method has good activity, selectivity and stability in use. | 08-29-2013 |
