Abstract: Systems and methods are provided for production of renewable jet fuel and/or jet fuel blending component fractions using a single stage reaction system. Although only a single separation stage is used, the systems and methods can reduce or minimize the volume of feedstock that is exposed to hydrocracking conditions while still producing a jet boiling range fraction having beneficial cold flow properties.

Abstract: Systems and methods are provided for using size-reversing materials in vessels where direct heating is used to at least partially provide heat for reforming reactions under cyclic reforming conditions. An example of a size-reversing material is the combination of NiO and Al2O3. It has been discovered that size-reversing materials can undergo a phase transition that can assist with re-dispersion of metal at elevated temperatures. This can assist with maintaining catalytic activity for reforming over longer time periods in the presence of cyclic reforming conditions.

Abstract: Methods for assessing lithology characteristics of bedforms within or relating to a subterranean formation using seismic data may include: assigning a bedform type to a bedform; extracting a cross-section of seismic data along the bedform in-line +/−15° with a fluid flow direction associated with the bedform; analyzing the cross-section to ascertain a structural characteristic of the bedform, wherein the structural characteristic comprises one or more of: a wavelength, a wave height, a bedform slope, a bedform asymmetry, a bedform migration, and a planform crest shape; and estimating a lithology for the bedform based on a correlation between (a) the lithology and (b) the bedform type and the structural characteristic.

Abstract: Processes and systems for producing isomeric mixtures of aromatic amine monomers from aromatic feeds. An example process for producing isomeric mixtures of aromatic amine monomers from aromatic feeds may include nitrating at least a portion of an aromatic feed to produce a mixture of nitrated aromatic compounds. The example process may further include hydrogenating at least a portion of the nitrated aromatic compounds to produce an isomeric mixture of aromatic amine monomers. The example process may further include processing the isomeric mixture of aromatic amine monomers to form a product selected from an aromatic compound with a different functional group than the aromatic amine monomers, a polymerized product, or a reaction product of the aromatic amine monomers and H2S.

Abstract: A method of assigning an octane number to a sample fuel based on the knock intensities obtained from a plurality of reference fuels each having a different assigned octane number while operating an engine at an established compression ratio. The knock intensities obtained from the plurality of reference fuels are plotted relative to the assigned octane numbers of the fuels. A line is fit to the plotted knock intensities. The octane number for a sample fuel is assigned based on the knock intensity obtained for the sample fuel, the knock intensity obtained from a prototype fuel having an assigned octane number, and the fitted line. In embodiments, an R squared value is obtained for the fitted line and compared with a minimum acceptable R squared value and the fitted line is validated if the R squared value is at least the minimum acceptable R squared value.

Abstract: A remote survey system includes an unmanned surface vehicle that includes a body, a propulsion system coupled to the body to provide mobility to the unmanned surface vehicle to traverse a surface of a waterbody, and a thickness detection assembly mounted to a hull of the body and including one or more thickness detection cameras. A central computer system is located at a command center and in wireless communication with the unmanned surface vehicle via a communication module. The one or more thickness detection cameras are positioned to obtain one or more images or videos of an air-oil-water interface on the surface of the waterbody, and a thickness of a released substance present on the surface of the waterbody is determined based on the one or more images or videos of the air-oil-water interface.

Abstract: A method of attenuating annular pressure buildup within a wellbore. The method includes accessing a wellbore, with the wellbore having an annulus disposed between first and second strings of casing. The method also includes placing a column of cement around the second string of casing generally below the first string of casing. The method further includes pumping a fluid mixture into the annulus, forming a fluid column. The fluid mixture comprises a carrier fluid, and a plurality of compressible particles dispersed in the carrier fluid. Each of the compressible particles is fabricated to partially collapse in response to thermal expansion of the fluid mixture. The method also includes placing a wellhead over the wellbore, thereby forming a trapped annulus in the wellbore. The method additionally includes at least partially sealing the annular region along at least one depth above the column of cement to inhibit vertical migration of the compressible particles.
