20080305947 | Highly Active Slurry Catalyst Composition - The instant invention is directed to the preparation of a slurry catalyst composition. The slurry catalyst composition is prepared in a series of steps, involving mixing a Group VIB metal oxide and aqueous ammonia to form an aqueous mixture and sulfiding the mixture to form a slurry. The slurry is then promoted with a Group VIII metal. Subsequent steps involve mixing the slurry with a hydrocarbon oil, and combining the resulting mixture with hydrogen gas (under conditions which maintain the water in a liquid phase) to produce the active slurry catalyst. | 12-11-2008 |

20090050526 | Process for Recycling an Active Slurry Catalyst Composition in Heavy Oil Upgrading - The instant invention is directed to a process employing slurry catalyst compositions in the upgrading of heavy oils. The slurry catalyst composition is not permitted to settle, which would result in possible deactivation. The slurry is recycled to an upgrading reactor for repeated use and products require no further separation procedures for catalyst removal. | 02-26-2009 |
20090057201 | HYDROPROCESSING BULK CATALYST AND USES THEREOF - A hydroprocessing bulk catalyst is provided. A process to prepare hydroprocessing bulk catalysts is also provided. The hydroprocessing catalyst has the formula (M | 03-05-2009 |
20090159495 | Heavy oil conversion - A method of converting heavy oil into one or more valuable products comprises hydroconverting heavy oil, recovering an effluent stream from the hydroconverting, and deep catalytic cracking the effluent stream. The hydroconverting comprises reacting a slurry comprising unsupported fine catalyst in heavy oil. The effluent stream comprises unsupported fine catalyst in unconverted heavy oil. The deep catalytic cracking converts unconverted heavy oil into one or more light oil products. | 06-25-2009 |
20090200204 | Hydroprocessing Bulk Catalyst and Uses Thereof - A hydroprocessing catalyst is provided. The hydroprocessing catalyst has the formula (M | 08-13-2009 |
20100065471 | Systems and Methods for Producing a Crude Product - Systems and methods for hydroprocessing a heavy oil feedstock, the system employs a plurality of contacting zones and separation zones with at least some of the fresh slurry catalyst being supplied to at least a contacting zone other than the first contacting zone. The contacting zones operate under hydrocracking conditions, employing the slurry catalyst for upgrading the heavy oil feedstock, forming upgraded products of lower boiling boiling hydrocarbons. In the separation zones, upgraded products are removed overhead and optionally, further treated in an in-line hydrotreater. A least a portion of the non-volatile fractions recovered from the separation zones is recycled back to the first contacting zone in the system. | 03-18-2010 |
20100234212 | HYDROPROCESSING BULK CATALYST AND USES THEREOF - A hydroprocessing bulk catalyst is provided. A process to prepare hydroprocessing bulk catalysts is also provided. The hydroprocessing catalyst has the formula (M | 09-16-2010 |
20120152806 | Hydroprocessing Catalysts and Methods for Making Thereof - A method to upgrade heavy oil feedstock using an ebullated bed reactor and a novel catalyst system is provided. The ebullated bed reactor system includes two different catalyst with different characteristics: an expanded catalyst zone containing particulate catalyst having a particle size of greater than 0.65 mm; and a slurry catalyst having an average particle size ranging from 1 to 300 μm. The slurry catalyst is introduced to the ebullated bed system with the heavy oil feedstock, and entrained in the upflowing hydrocarbon liquid passing through the ebullated bed reaction zone. The slurry catalyst reduces the formation of sediment and coke precursors in the ebullating bed reactor system. The slurry catalyst is prepared from at least a water-soluble metal precursor and pre-sulfided prior to being introduced with the heavy oil feedstock to the reactor system, or sulfided in-situ in the ebullated bed reactor in another embodiment. | 06-21-2012 |
