  • Patent number: 11859141
    Abstract: A desolidification process enables the isolation and extraction of solid additives from an unreacted petroleum residue stream. In a hydrocracking process that mixes a solid additive with a petroleum residue feedstock to convert the petroleum residue to higher-value distillates, the desolidification process enables the recovery of the unreacted petroleum residue for conversion to a saleable product. The desolidification process involves the mixture of one or more solvents with a slurry in which solids are integrated in the petroleum residue to generate a mixture having a decreased density and viscosity as compared to the slurry, which facilitates removal of the solids.
    Type: Grant

  • Publication number: 20230211303
    Abstract: A system for processing a hydrocarbon feed has a final stage reactor and internal separator with cyclone that forms a substantially gas stream and a substantially non-gas stream. The substantially gas stream is sent directly from the final stage reactor and separator to further downstream processing.

  • Publication number: 20140275672
    Abstract: Methods and systems for idling a hydrocracker are provided. The method can include hydrocracking a hydrocarbon in the presence of a catalyst and hydrogen in a reactor to produce a hydrocracked product. A kill agent can be introduced to the reactor in an amount sufficient to reduce hydrocracking by at least 10% therein. In some examples, the kill agent can include one or more nitrogen-containing compounds, such as ammonia, amines, anilines, ammonia-containing compounds, amine-containing compounds, or, aniline-containing compounds. In some examples, the catalyst can include one or more Group VIII metals (e.g., cobalt, nickel, palladium, iron, alloys thereof), one or more Group VIB metals (e.g., molybdenum, tungsten, alloys thereof, or oxides thereof), and a catalyst support, such as a zeolite.
