Methods of refining a whole crude oil stream. The methods involve first processing the crude either through a hydrotreating reactor comprising a dewaxing reactor bed or a flash evaporation separator. The treated streams are then further processed through a demetalization reactor bed, a hydroprocessing reactor bed, or both. The stream can then be still further processed via additional hydrotreating, distillation, or both.

This disclosure relates to new processes to produce high paraffinic diesel from crude oil, such as tight oil from the Permian basin. This disclosure also relates to high paraffinic diesel compositions and high paraffinic diesel blends.

Method of refining whole crude oil or a wide cut crude oil, the methods comprising a combination of a hydrotreating reactor, a distillation tower, and an optional flash evaporation separator. The methods can also include light ends processing, fluid catalytic cracking, reforming, hydrocracking, and demetalization. In some methods a whole crude oil is first processed through a flash evaporation separator to create a wide cut crude oil and in other methods, the flash evaporation separator is not used as the whole crude oil is first treated in a hydrotreater.

Disclosed is a method of producing a lubricating base oil, including providing a feedstock including a diesel fraction, subjecting the feedstock to catalytic dewaxing, and recovering a lubricating base oil from a product of the catalytic dewaxing. A lubricating base oil produced thereby and a lubricant product including the lubricating base oil are also provided.

Processes for preparing a low particulate liquid hydrocarbon product are provided and include blending a tar stream containing particles with a fluid and heating to a temperature of 250° C. or greater to produce a fluid-feed mixture that contains tar, the particles, and the fluid. The fluid-feed mixture contains about 20 wt % or greater of the fluid, based on a combined weight of the tar stream and the fluid. Also, about 25 wt % to about 99 wt % of the particles in the tar stream are dissolved or decomposed when producing the fluid-feed mixture.

A process for purification a hydrocarbon stream including: (a) Providing a hydrocarbon stream having a diene value of at least 1.0, a bromine number of at least 5 g and containing at least 10 wt % of pyrolysis plastic oil; b) contacting the effluent obtained in step a) with a silica gel, clays, alkaline or alkaline earth metal oxide, iron oxide, ion exchange resins, active carbon, active aluminium oxide, molecular sieves, alkaline oxide and/or porous supports, and/or silica gel, or any mixture thereof; c) performing a first hydrotreating step; d) contacting the effluent obtained in step c) with silica gel, clays, alkaline or alkaline earth metal oxide, iron oxide, ion exchange resins, active carbon, active aluminium oxide, molecular sieves, alkaline oxide and/or porous supports and silica gel, or any mixture thereof; e) performing a second hydrotreating step; and f) recovering a purified hydrocarbon stream.

A process for maximizing production of heavy naphtha from a hydrocarbon stream is disclosed. The process comprises providing a hydrocarbon feed stream comprising diesel to a separation column to provide a light diesel stream and a heavy diesel stream. The heavy diesel stream is hydrocracked in the presence of a hydrogen stream and a first hydrocracking catalyst in a first hydrocracking reactor at a first hydrocracking pressure of 13790 kPa to 17237 kPa to provide a first hydrocracked effluent stream. The light diesel stream is hydrocracked in the presence of a hydrogen stream and a second hydrocracking catalyst in a second hydrocracking reactor at a second hydrocracking pressure of 3450 kPa to 6205 kPa to provide a second hydrocracked effluent stream. At least a portion of the first hydrocracked effluent stream and at least a portion of the second hydrocracked effluent stream are fractioned to produce heavy naphtha.
