  • Patent number: 9446998
    Abstract: The present invention relates to a new process which comprises the steps of hydrotreating, paraffin disproportionation and hydroisomerization to convert biological hydrocarbonaceous oxygenated oils comprising triglycerides into biologically-derived paraffinic jet/diesel fuels, solvents and base oils. A combination of conventional hydrogenation/dehydrogenation catalysts, such as Pt/Al2O3, and conventional olefin metathesis catalysts, such as WO3/SiO2, or inexpensive variations thereof, is generally employed in the paraffin disproportionation step.

  • Patent number: 9404049
    Abstract: A process and system are described for the processing of gas associated with crude oil production, i.e. associated gas. A separation complex is used to separate produced fluids produced from a hydrocarbon reservoir into crude oil, liquefied petroleum gas, water, and natural gas. At least a portion of the natural gas is converted into synthesis gas in a synthesis gas generator. A combination of a synthesis gas conversion catalysts and hydroconversion catalysts are used in a synthesis gas reactor to convert the synthesis gas into a liquid effluent stream containing liquefied petroleum gas and a synthetic crude oil. The liquefied petroleum gas and synthetic crude oil from the synthesis gas reactor is sent to the separation complex. Liquefied petroleum gas is separated both from the synthetic crude oil and a natural crude oil obtained from the produced fluids.

  • Publication number: 20160209102
    Abstract: A refrigerator appliance including a cabinet defining a chilled chamber and a first slide assembly is provided. The first slide assembly is mounted to the cabinet at least partially within the chilled chamber. The refrigerator appliance also includes a door with a frame having a first frame member rotatably attached to the first slide assembly at a first pivot joint. The door is rotatable about the lateral direction at the first pivot joint between an inwardly tilted position and an outwardly tilted position. In the inwardly tilted position the door defines an acute angle with the first slide assembly, and in the outwardly tilted position the door defines an obtuse angle with the first slide assembly. Such a configuration may allow the door to form a more complete seal with the cabinet of the refrigerator appliance despite any, e.g., surface variations of the cabinet.

  • Patent number: 9390875
    Abstract: Electromagnetic actuators capable of generating a symmetrical bidirectional force are disclosed. The electromagnetic actuators include a housing made of a ferromagnetic material and a shaft made of a magnetically inert material movable along an axis within the housing. In one type of actuator, captive permanent magnets are arranged on opposite interior end walls of the housing and an electromagnetic coil is mounted on a central portion of the shaft. The electromagnetic coil is capable of generating a force when energized that causes linear displacement of the shaft in either direction along its axis depending on the direction of current through the electromagnetic coil. In another type of actuator, captive electromagnetic coils are arranged on opposing inner end walls of the housing, and a permanent magnet is mounted on a central portion of the shaft.

  • Publication number: 20160122658
    Abstract: Particulate mercury, in the form of metacinnabar, is removed from crude oil by thermally treating the crude oil at temperatures in a range from 150° C. to 350° C. and at a pressure sufficient to limit the amount of crude vaporizing to no more than 10 wt. %. In the thermal treatment, the particulate mercury is converted into elemental mercury, which can be removed by directly adsorption from the crude onto a support. In one embodiment, the elemental mercury can be removed by stripping the crude with a gas, and then adsorbing the mercury onto a support. The crude oil can be optionally treated prior to stabilization and contains 0.1 wt. % or more of C4-hydrocarbons. Following the thermal treatment, the treated crude is cooled and the pressure is reduced. The C4-hydrocarbons then vaporize from the crude and carry the elemental mercury with them. The elemental mercury in this hydrocarbon gas stream may then be removed by a solid adsorbent.
