    Abstract: The present embodiment describes a method of forming different layers in a solid oxide fuel cell. The method begins by preparing slurries which are then delivered to a spray nozzle. The slurries are then atomized and sprayed subsequently onto a support to produce a layer which is then dried. In this embodiment different layers can comprise an anode, an electrode and a cathode. Also, the support can be a metal or a metal oxide which is later removed.

    Abstract: The present disclosure relates generally to processes and systems for producing liquid transportation fuels by converting a feed stream that comprises both isopentane and n-pentane, and optionally, some C6+ hydrocarbons. Isopentane and smaller hydrocarbons are separated to form a first fraction while n-pentane and larger components of the feed stock form a second fraction. Each fraction is then catalytically-activated in a separate reaction zone with a separate catalyst, where the conditions maintained in each zone maximize the conversion of each fraction to olefins and aromatics, while minimizing the production of C1-C4 light paraffins. In certain embodiments, the first fraction is activated at a lower temperature than the second fraction. Certain embodiments additionally comprise mixing at least a portion of the two effluents and contacting with an alkylation catalyst to provide enhanced yields of mono-alkylated aromatics that are suitable for use as a blend component of liquid transportation fuels or other value-added chemical products.

    Abstract: The invention relates to injecting steam into crude oil for several benefits, primarily of which is to remove salt by transferring the salt into the condensed water from the steam. Steam transfers salt via a different transfer mechanism and therefore doesn't require the high shear mixing of conventional water injection systems. As such, steam injection through a variety of procedures, is more efficient at gathering salt into water that itself is easier to remove from the crude oil.

    Abstract: Processes and systems for maintaining a live culture of activated sludge in the activated sludge unit of a petroleum refinery during an extended refinery shut-down. In the absence of a source of refinery wastewater, a living culture of activated sludge comprising aerobic prokaryotes and/or eukaryotes that nitrify ammonia is maintained by redirecting at least a portion of clarified wastewater leaving the clarifier portion of an activated sludge unit. The redirected clarified wastewater is mixed with an organic food source that may be ammonia and/or ethyl acetate, a source of phosphate ion, and the pH is adjusted to produce a growth media that is returned to the aeration chamber of the activated sludge unit. After a time exceeding one week, the input of refinery wastewater to the aeration chamber is resumed while discontinuing the redirecting of the clarified wastewater.

    Abstract: The invention relates to injecting steam into crude oil in two separate desalting steps to remove salt by transferring the salt into the condensed water from the steam and gravity separating the water from the crude oil. Steam transfers salt from crude oil via a different transfer mechanism. In the invention, salt is also removed via an intermediate step of adding water with harshly mixing the added water with the crude oil between the gravity separation of the first steam desalting step and before steam is added in the second step.

    Abstract: The invention relates to removing salt from crude oil via two steps of adding water with harsh mixing of the added water with the crude oil and gravity separating the salty water between steps where the process additionally includes a step of injecting steam into the crude oil after the first of the two water adding and harsh mixing desalting steps, but upstream of the gravity separation of the first step. The steam separates salt by transferring the salt into the condensed water from the steam.
