  • Slurry hydroconversion using enhanced slurry catalysts
    Patent number: 10035959
    Abstract: Systems and methods are provided for slurry hydroconversion of a heavy oil feed, such as an atmospheric or vacuum resid. The systems and methods allow for slurry hydroconversion using catalysts with enhanced activity and/or catalysts that can be recycled as a side product from a complementary refinery process.
    Type: Grant
    Filed: June 19, 2014
    Date of Patent: July 31, 2018
    Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANY

  • Integrated hydrocracking and slurry hydroconversion of heavy oils
    Patent number: 9605218
    Abstract: Improved yields of fuels and/or lubricants from a resid or other heavy oil feed can be achieved using slurry hydroconversion to convert at least about 90 wt % of the feed. The converted portion of the feed can then be passed into one or more hydroprocessing stages. An initial processing stage can be a hydrotreatment stage for additional removal of contaminants and for passivation of high activity functional groups that may be created during slurry hydroconversion. The hydrotreatment effluent can then be fractionated to separate naphtha boiling range fractions from distillate fuel boiling range fractions and lubricant boiling range fractions. At least the lubricant boiling range fraction can then be hydrocracked to improve the viscosity properties. The hydrocracking effluent can also be dewaxed to improve the cold flow properties. The hydrocracked and/or dewaxed product can then be optionally hydrofinished.

  • Sequential slurry hydroconversion of heavy oils
    Patent number: 9605217
    Abstract: Systems and methods are provided for sequential slurry hydroconversion of heavy oil feedstocks. One or more low pressure slurry hydroconversion stages can be used to perform a majority of the conversion of a heavy oil feedstock. The bottoms from the low pressure stages can then be slurry hydroconverted in one or more high pressure stages to further convert the feedstock.

  • Slurry hydroconversion with high activity catalysts
    Patent number: 9499752
    Abstract: Systems and methods are provided for slurry hydroconversion of a heavy oil feed, such as an atmospheric or vacuum resid. The systems and methods allow for slurry hydroconversion using catalysts with enhanced activity. The catalysts with enhanced activity can be used in conjunction with demetallization catalysts or catalysts that can be recycled as a side product from a complementary refinery process.
