Systems and methods are provided for catalytic hydroprocessing to form lubricant base oils. The methods can include performing high pressure hydrofinishing after fractionating the hydrotreated and/or hydrocracked and/or dewaxed effluent. Performing hydrofinishing after fractionation can allow the high hydrogen pressure for hydrofinishing to be used on one or more lubricant base oil fractions that are desirable for high pressure hydrofinishing. This can allow for improved aromatic saturation of a lubricant base oil product while reducing or minimizing the hydrogen consumption. The high pressure hydrofinishing can be performed at a hydrogen partial pressure of at least about 2500 psig (&#x2dc;17.2 Mpa), or at least about 2600 psig (&#x2dc;18.0 Mpa), or at least about 3000 psig (&#x2dc;20.6 MPa). The high pressure hydrofinishing can allow for formation of a lubricant base oil product with a reduced or minimized aromatics content, a reduced or minimized 3-ring aromatics content, or a combination thereof.

High pressure hydrofinishing for lubricant base oil production

Methods are provided for forming lubricant base stocks from feeds such as vacuum resid or other 510&#xb0; C.+ feeds. A feed can be deasphalted and then catalytically and/or solvent processed to form lubricant base stocks, including bright stocks that are resistant to haze formation.

A system for treating ambient air is provided. The system includes a flow control structure disposed on a vehicle. The flow control structure is adapted to control flow of ambient air received during movement of the vehicle. The system further includes an actuator operatively coupled to the flow control structure. The actuator is adapted to movably adjust the flow control structure. The system further includes a controller disposed on the vehicle and communicably coupled to the actuator. The controller is configured to control the actuator based on at least a quality of ambient air. The system further includes an air treatment component for selectively receiving ambient air from the flow control structure. The air treatment component is adapted to treat at least one pollutant present in ambient air.

System and method for treating ambient air

An exhaust aftertreatment system may include a reductant tank, a gaseous ammonia source, an injector, first conduit and a second conduit. The injector may receive the liquid reductant from the reductant tank and the gaseous ammonia from the gaseous ammonia source and inject the liquid reductant into a stream of exhaust gas in a first mode, inject the gaseous ammonia into the stream of exhaust gas in a second mode, and both the liquid reductant and the gaseous ammonia into the stream of exhaust gas in a third mode. The first conduit may communicate liquid reductant from the reductant tank to the injector. The second conduit may communicate gaseous ammonia from the gaseous ammonia source to the injector.

Systems and methods are provided for producing lubricant basestocks having a reduced or minimized aromatics content. A first processing stage can perform an initial amount of hydrotreating and/or hydrocracking. A first separation stage can then be used to remove fuels boiling range (and lower boiling range) compounds. The remaining lubricant boiling range fraction can then be exposed under hydrocracking conditions to a USY catalyst including a supported noble metal, such as Pt and/or Pd. The USY catalyst can have a desirable combination of catalyst properties, such as a unit cell size of 24.30 or less (or 24.24 or less), a silica to alumina ratio of at least 50 (or at least 80), and an alpha value of 20 or less (or 10 or less). In some aspects, the effluent from the second (hydrocracking) stage can be dewaxed without further separation. In such aspects, a portion of the dewaxed effluent can be used as a recycle quench stream to cool the hydrocracking effluent prior to entering the dewaxing reactor.

Lubricant basestock production with enhanced aromatic saturation

The present disclosure provides a method of producing an insulation preform having graded porosity for an exhaust treatment component of a vehicle. The method includes obtaining a first granular insulating material having a first diameter, a second granular insulating material having a second diameter less than the first diameter, an inorganic binder, and water. The method further includes producing a slurry comprising the first granular insulating material, the second granular insulating material, the inorganic binder, and water. The slurry is introduced into a mold having at least one surface adapted for vacuum extraction. A liquid phase of the slurry is evacuated from the mold using vacuum extraction to produce a moist preform. The moist preform has graded porosity such that a greater concentration of the second insulation material is adjacent to the at least one surface than the first insulating material. The moist preform is heated to produce the insulation preform.

Apparatus and method of producing insulation preform with graded porosity

An after-treatment system including an exhaust treatment component provided in an exhaust passage, a tank carrying an aqueous reagent, and an electrochemical cell in communication with the tank and configured to receive the aqueous reagent therefrom. The electrochemical cell is configured to convert the aqueous reagent into a first exhaust treatment fluid and a second exhaust treatment fluid. A controller is in communication with the electrochemical cell. The controller is configured to vary amounts and/or composition of each of the first exhaust treatment fluid and the second exhaust treatment fluid produced by the electrochemical cell. An injector is in communication with the electrochemical cell and the exhaust passage, and is configured to receive one of the first exhaust treatment fluid or the second exhaust treatment fluid from the electrochemical cell, and dose the one exhaust treatment fluid into the exhaust passage at a location upstream from the exhaust treatment component.

Exhaust after-treatment system including ammonia and hydrogen generation

Feeds containing triglycerides are processed to produce an olefinic diesel fuel product. The olefinic diesel can optionally be oligomerized to form a lubricant base oil product. The olefinic diesel is generated by deoxygenating the triglyceride-containing feed using processing conditions that enhance preservation of olefins that are present in the triglycerides. The triglyceride-containing feed is processed in the presence of a catalyst containing a Group VI metal or a Group VIII metal and optionally a physical promoter metal.

Production of olefinic diesel and corresponding oligomers

An exhaust aftertreatment system may include a reductant tank, a reactor system, a storage tank, a first conduit and a second conduit. The reactor system may receive reductant from the reductant tank and may output a gas comprising ammonia. The storage tank may receive gas comprising ammonia from the reactor system and may store a volume of gas comprising ammonia. The first conduit may communicate gas comprising ammonia from the reactor system to a stream of exhaust gas. The first conduit may bypass the storage tank. The second conduit may communicate gas comprising ammonia from the storage tank to the stream of exhaust gas.

Feeds containing triglycerides are processed to produce a diesel fuel product and propylene. The diesel product and propylene are generated by deoxygenating the triglyceride-containing feed using processing conditions that enhance preservation of olefins that are present in the triglycerides. The triglyceride-containing feed is processed in the presence of a catalyst containing a Group VI metal and a Group VIII non-noble metal and in the presence of CO.

Production of renewable diesel and propylene

Feedstocks containing biocomponent materials are coprocessed with mineral feeds using a Group VI metal catalyst prior to hydrodesulfurization of the feedstocks. The Group VI metal catalyst is optionally a physically promoted Group VI metal catalyst.

Coprocessing of biofeeds with group VI metal catalysts

An integrated process for producing naphtha fuel, diesel fuel and/or lubricant base oils from feedstocks under sour conditions is provided. The ability to process feedstocks under higher sulfur and/or nitrogen conditions allows for reduced cost processing and increases the flexibility in selecting a suitable feedstock. The sour feed can be delivered to a catalytic dewaxing step without any separation of sulfur and nitrogen contaminants. The integrated process includes an initial dewaxing of a feed under sour conditions, optional hydrocracking of the dewaxed feed, and a separation to form a first diesel product and a bottoms fraction. The bottoms fraction is then exposed to additional hydrocracking and dewaxing to form a second diesel product and optionally a lubricant base oil product. Alternatively, a feedstock can be hydrotreated, fractionated, dewaxed, and then hydrocracked to form a diesel fuel and a dewaxed, hydrocracked bottoms fraction that is optionally suitable for use as a lubricant base oil.

Integrated hydrocracking and dewaxing of hydrocarbons

Provided are processes for making hydrocarbons from renewable feed sources. In an embodiment, there is provided a method for co-producing lube basestock and transportation fuel from a feedstock of biological origin, the method including: a) converting a feedstock of biological origin to a ketone or a dimer acid in the presence of a first catalyst; and b) hydrogenating the ketone or the dimer acid to produce a hydrocarbon in the presence of a second catalyst comprising a hydrogenation catalyst and a hydrothermally stable binder.

Process for making lube base stocks from renewable feeds

Methods are provided herein for co-processing of biocomponent feeds as well processing of mineral feeds in a reaction system at hydrogen partial pressures of about 500 psig (3.4 MPag) or less. The methods include using stacked beds of both CoMo and NiMo catalysts. The stacked catalyst beds provided unexpectedly high catalyst activity as the input feed to a reaction system was switched between a mineral feed and a feed containing both mineral and biocomponent portions. Additionally, use of stacked catalyst beds can allow for maintenance of the activity for the catalyst system in a reaction system while still achieving a desired activity for both types of feeds.
