Abstract: Slurry hydrocracking processes are described. The methods include hydrotreating a heavy residual hydrocarbon feed in a hydrotreating zone under residual hydrotreating conditions to form a hydrotreated effluent. The hydrotreated effluent is separated in an first separator to form an overhead vapor stream and a bottoms stream. The bottoms stream is hydrocracked in a slurry hydrocracking zone under slurry hydrocracking conditions. The effluent from the slurry hydrocracking zone is fractionated in a fractionation zone into at least two streams. Slurry hydrocracking apparatus is also described.

Abstract: A process for converting Fischer-Tropsch liquids and waxes into lubricant base stock and/or transportation fuels is disclosed. The process includes the steps of feeding a Fischer-Tropsch wax to a first isomerization unit to produce an isomerized Fischer-Tropsch wax product; combining a Fischer-Tropsch liquid with the isomerized Fischer-Tropsch wax product to create a mixture of the Fischer-Tropsch liquid and the Fischer-Tropsch wax product; and feeding the mixture to a fractionation column to separate the mixture into a lubricant base stock fraction and at least one transportation fuel fraction.

Abstract: Two-stage hydroprocessing uses a common dividing wall fractionator. Hydroprocessed effluents from both stages of hydroprocessing are fed to opposite sides of the dividing wall.

Abstract: Method, computer program product, and system to perform an operation for a deep question answering system. The operation begins by computing a concept score for a first concept in a first case received by the deep question answering system, the concept score being based on a machine learning concept model for the first concept. The operation then excludes the first concept from consideration when analyzing a candidate answer and an item of supporting evidence to generate a response to the first case upon determining that the concept score does not exceed a predefined concept minimum weight threshold. The operation then increases a weight applied to the first concept when analyzing the candidate answer and the item of supporting evidence to generate the response to the first case when the concept score exceeds a predefined maximum weight threshold.

Abstract: Crude tall oil is subjected to a distillation process that substantially removes impurities. The process produces a combined pitch and a distillate of free fatty acids and rosin acids from two vacuum columns. The distillate stream is amenable to further downstream hydroprocessing.

Abstract: Methods of making synthetic distillate fuel are described. The methods involve the use of an absorbent bed of molecular sieves which adsorb the n-paraffins from a distillate fuel cut. This allows the distillate fuel true boiling point cut point on the distillation column to increase to a higher temperature to make a distillate fuel which meets all of the synthetic paraffinic kerosene (SPK) or synthetic diesel specifications on distillation as well as the cold flow property specification, such as freeze point for SPK or cloud point, cold filter plugging point and pour point for synthetic diesel. This approach could improve aviation fuel yields by about 5 to about 10% and synthetic diesel yields up to 20%.

Abstract: A process is provided to produce an ultra low sulfur diesel using a two stage hydrotreating reaction zone. The first stage hydrotreater may operate with a continuous liquid phase.

Abstract: Methods for processing a hydrocarbonaceous feedstock flows are provided. In one aspect, the method includes providing two or more hydroprocessing stages disposed in sequence, each hydroprocessing stage having a hydroprocessing reaction zone with a hydrogen requirement and each stage in fluid communication with the preceding stage. A hydrogen source is provided substantially free of hydrogen from a hydrogen recycle compressor. The hydrocarbonaceous feedstock flow is separated into an portions of fresh feed for each hydroprocessing stage, and the first portion of fresh feed to the first hydroprocessing stage is heated. The heated first portion of fresh feed is supplied with hydrogen from the hydrogen source in an amount satisfying substantially all of the hydrogen requirements of the hydroprocessing stages to a first hydroprocessing zone. The unheated second portion of fresh feed is admixed with effluent from previous stage to quench the hot reactor effluent before entering a second stage.

Abstract: A method of hydroprocessing hydrocarbons is provided using a substantially liquid-phase reactor having first and second catalyst beds with a heat transfer section positioned therebetween. The first and second catalyst beds and the heat transfer section are combined within the same reactor vessel. Each catalyst bed having an inlet temperature and an exit temperature and having a hydroprocessing catalyst therein with a maximum operating temperature range.

Abstract: A process has been developed for producing fuel from renewable feedstocks such as plant and animal oils and greases. The process involves treating a first portion of a renewable feedstock by hydrogenating and deoxygenating in a first reaction zone and a second portion of a renewable feedstock by hydrogenating and deoxygenating in a second reaction zone and treating the effluents in a finishing reaction zone to provide a diesel boiling point range fuel hydrocarbon product. If desired, the hydrocarbon product can be isomerized to improve cold flow properties. A portion of the hydrocarbon product is recycled to the first reaction zone to increase the hydrogen solubility of the reaction mixture.
