20100006475 | CATALYST COMPOSITION AND A PROCESS THAT USES THE CATALYST COMPOSITION FOR THE HYDROCONVERSION OF A HEAVY HYDROCARBON FEEDSTOCK - A catalyst composition that provides for a high percentage conversion of the pitch component of a heavy hydrocarbon feedstock and a process of using the catalyst composition. The catalyst composition comprises a nickel component, a molybdenum component in an amount less than 12 wt % of the catalyst composition, and it may also include an alumina support material having special properties. The weight ratio of the nickel component-to-molybdenum component exceeds 0.25, and the support material preferably has a median pore diameter of from 100-140 Å. The catalyst composition has a characteristically unique Raman spectrum that distinguishes it over other compositions. | 01-14-2010 |
20100243526 | HIGH SURFACE AREA COMPOSITION FOR USE IN THE CATALYTIC HYDROCONVERSION OF A HEAVY HYDROCARBON FEEDSTOCK, A METHOD MAKING SUCH COMPOSITION AND ITS USE - A catalyst composition that is especially useful in the hydroconversion of pitch, micro carbon residue and sulfur contents of a heavy hydrocarbon feedstock without the excessive formation of sediment. The catalyst composition is a reasonably high surface area composition containing alumina and a low molybdenum content with a high ratio of nickel-to-molybdenum. The catalyst composition further has a unique pore distribution that in combination with the special metals loading provide for good conversion of pitch and micro carbon residue without an excessive yield of sediment. | 09-30-2010 |
20100276339 | PROCESS AND CATALYST FOR THE HYDROCONVERSION OF A HEAVY HYDROCARBON FEEDSTOCK - A method of hydroprocessing a heavy hydrocarbon feedstock using a hydroprocessing catalyst having specific properties making it effective in the hydroconversion of at least a portion of the heavy hydrocarbon feedstock to lighter hydrocarbons. The hydroprocessing catalyst comprises a Group VIB metal component (e.g., Cr, Mo, and W), a Group VIII metal component (e.g., Ni and Co) and, optionally, a potassium metal component that are supported on a support material comprising alumina. The alumina has novel physical properties that, in combination with the catalytic components, provide for the hydroprocessing catalyst. The hydroprocessing catalyst is particularly effective in the conversion of the heavy hydrocarbon feedstock. The alumina is characterized as having a high pore volume and a high surface area with a large proportion of the pore volume being present in the pores within a narrow pore diameter distribution about a narrowly defined range of median pore diameters. The support material preferably does not contain more than a small concentration of silica. The alumina component is preferably made by a specific method that provides for an alumina having the specific physical properties required for the hydroprocessing catalyst. | 11-04-2010 |
20100326889 | METHOD OF RESTORING CATALYTIC ACTIVITY TO A SPENT HYDROTREATING CATALYST, THE RESULTING RESTORED CATALYST, AND A METHOD OF HYDROPROCESSING - A method of restoring catalytic activity to a spent hydroprocessing catalyst that has a first carbon concentration. The concentration of carbon on the spent hydroprocessing catalyst is reduced to provide a carbon-reduced catalyst having a second carbon concentration that is less than the first carbon concentration. The carbon-reduced catalyst is exposed to a solution, comprising a chelating agent and a solvent, for an aging time period sufficient to provide for a restored catalytic activity thereby resulting in an aged catalyst having incorporated therein the chelating agent and the solvent. The aged catalyst is exposed to conditions, including a drying temperature, so as to remove from the aged catalyst a portion of the solvent without removing a significant portion of the chelating agent from the aged catalyst thereby resulting in a dried aged catalyst. The dried aged catalyst is then sulfur treated to thereby provide a restored catalyst. The restored catalyst and those catalysts made by the treatment method can be used in a hydroprocessing process comprising contacting the restored catalyst with a hydrocarbon feedstock under hydroprocessing conditions. | 12-30-2010 |
