Hydroprocessing method and system for upgrading heavy oil using a colloidal or molecular catalyst
ActiveUS20050241993A1Inhibits eliminates formationEasy to useCatalyst regeneration/reactivationCatalyst activation/preparationColloidFuel oil
Methods and systems for hydroprocessing heavy oil feedstocks to form an upgraded material involve the use of a colloidal or molecular catalyst dispersed within a heavy oil feedstock, a hydrocracking reactor, and a hot separator. The colloidal or molecular catalyst promotes hydrocracking and other hydroprocessing reactions within the hydrocracking reactor. The catalyst is preferentially associated with asphaltenes within the heavy oil feedstock, which promotes upgrading reactions involving the asphaltenes rather than formation of coke precursors and sediment. The colloidal or molecular catalyst overcomes problems associated with porous supported catalysts in upgrading heavy oil feedstocks, particularly the inability of such catalysts to effectively process asphaltene molecules. The result is one or more of reduced equipment fouling, increased conversion level, and more efficient use of the supported catalyst if used in combination with the colloidal or molecular catalyst.

This invention relates to a novel method for economically processing vacuum residue from heavy crude oils by selectively processing the difficult and easy components in reactors whose design and operating conditions are optimized for the specific feed. The process utilizes an integrated solvent deasphalting (SDA) / ebullated-bed design wherein the heavy vacuum residue feedstock is initially sent to an SDA unit operated with C4 / C5 solvent to achieve a high deasphalted oil (DAO) yield. The resulting SDA products, namely asphaltenes and DAO are separately treated in ebullated-bed reactor(s) systems whose design and operating conditions are optimized for a particular feedstock. The resulting net conversion, associated distillate yield and product qualities are greatly improved relative to treatment of the entire residue feedstock in a common ebullated-bed reactor system.
