  • Patent number: 9816039
    Abstract: A heavy petroleum oil feed is upgraded by having its amenability to cracking improved by subjecting the oil to selective partial oxidation with a catalytic oxidation system to partially oxidize aromatic ring systems in the heavy oil. The partially oxidized oil can then be cracked in the conventional manner but at lower severities to lower molecular weight cracking products. The cracking following the partial oxidation step may be thermal in nature as by thermal cracking, delayed, contact or fluid coking or fluid catalytic cracking or hydrogenative as in hydrocracking.

  • 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.

  • 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.

  • Patent number: 6617482
    Abstract: A process is described for removing polar compounds from an aromatic feedstock which contains polar compounds and which is then used in an alkylation process. The process comprises contacting the feedstock in an adsorption zone at a temperature of less than or equal to 130° C. with an adsorbent selective for the adsorption of said polar compounds and comprising a molecular sieve having pores and/or surface cavities with cross-sectional dimensions greater than 5.6 Angstroms. A treated feedstock substantially free of said polar compounds is withdrawn from the adsorption zone and fed to an alkylation zone for contact under liquid phase alkylation conditions with an alkylating agent in the presence of an alkylation catalyst.
