Integrated processes and systems for the production of distillate hydrocarbons and coke. The process may include feeding a hydrocarbon feedstock, comprising a residuum hydrocarbon fraction, to a residue hydrocracking reactor system to convert hydrocarbons therein, producing a hydrocracked effluent. The hydrocracked effluent may then be fed to a separation system, separating the hydrocracked effluent into one or more distillate hydrocarbon fractions and a vacuum residue fraction. The vacuum residue fraction may be fed to a coker system, converting the vacuum residue fraction into a coke product and a coker vapor effluent, recovering the coke product, and feeding the coker vapor effluent to the separation system. The one or more distillate hydrocarbon fractions are hydroprocessed to produce a hydroprocessed effluent, and the hydroprocessed effluent is separated into product distillate hydrocarbon fractions.

Integrating ebullated bed hydrocracking and coking units

A process for upgrading vacuum residuum and vacuum gas oil hydrocarbons is disclosed. The process may include: contacting a heavy distillate hydrocarbon fraction and hydrogen with a zeolite selective hydrocracking catalyst in a first ebullated bed hydrocracking reaction zone to convert at least a portion of the vacuum gas oil to lighter hydrocarbons. Contacting a residuum hydrocarbon fraction and hydrogen with a non-zeolite base metal hydroconversion catalyst in a second ebullated bed hydroconversion reaction zone may produce a vapor stream containing unconverted hydrogen, acid gases and volatilized hydrocarbons which may be fed along with the vacuum gas oil in the first ebullated bed hydrocracking zone.

The disclosure includes technology for providing custom content for display. In an example embodiment, a computer-implemented method includes storing unique customer types in a non-transitory computer storage device; storing in the computer storage device custom contents in association with one or more of the different customer types; receiving at a user device or a server coupled to the user device interaction data from the user device of a user describing an interaction by the user with a site presented for display to the user on the user device; determining by the user device or the server a customer type for the user; querying by the user device or the server the custom contents stored on the computer storage device for a custom content matching the customer type and associated with the interaction data; and presenting the custom content to the user via the display of the user device.

Embodiments herein relate to a process flow scheme for the processing of gas oils and especially reactive gas oils produced by thermal cracking of residua using a split flow concept. The split flow concepts disclosed allow optimization of the hydrocracking reactor severities and thereby take advantage of the different reactivities of thermally cracked gas oils versus those of virgin gas oils. This results in a lower cost facility for producing base oils as well as diesel, kerosene and gasoline fuels while achieving high conversions and high catalyst lives.

Hydroprocessing thermally cracked products

A process for converting triacylglycerides-containing oils into crude oil precursors and/or distillate hydrocarbon fuels is disclosed. The process may include: reacting a triacylglycerides-containing oil-water-hydrogen mixture at a temperature in the range from about 250&#xb0; C. to about 525&#xb0; C. and a pressure greater than about 75 bar to convert at least a portion of the triacylglycerides and recovering a reaction effluent comprising water and one or more of isoolefins, isoparaffins, cycloolefins, cycloparaffins, and aromatics; hydrotreating the reaction effluent to form a hydrotreated effluent.

Conversion of triacylglycerides-containing oils to hydrocarbons

A process for converting triacylglycerides-containing oils into crude oil precursors and/or distillate hydrocarbon fuels is disclosed. The process may include: reacting a triacylglycerides-containing oil-water-diatomic hydrogen mixture at a temperature in the range from about 250&#xb0; C. to about 560&#xb0; C. and a pressure greater than about 75 bar to convert at least a portion of the triacylglycerides and recovering a reaction effluent comprising water and one or more of isoolefins, isoparaffins, cycloolefins, cycloparaffins, and aromatics; and hydrotreating the reaction effluent to form a hydrotreated effluent.

Conversion of triacylglycerides-containing oils to jet fuel range hydrocarbons

Integrated processes for upgrading crude shale-derived oils, such as those produced by oil shale retorting or by in situ extraction or combinations thereof. Processes disclosed provide for a split-flow processing scheme to upgrade whole shale oil. The split flow concepts described herein, i.e., naphtha and kerosene hydrotreating in one or more stages and gas oil hydrotreating in one or more stages, requires additional equipment as compared to the alternative approach of whole oil hydrotreating. While contrary to conventional wisdom as requiring more capital equipment to achieve the same final product specifications, the operating efficiency vis a vis on-stream time efficiency and product quality resulting from the split flow concept far exceed in value the somewhat incrementally higher capital expenditure costs.
