Abstract: Disclosed herein are processes and systems that utilize olefin cross metathesis of triglycerides to produce jet fuel such as hydrocarbons with carbons numbers from C9 to C16. Jet range hydrocarbons may include paraffins, naphthenes, and aromatics with carbon numbers from 9 to 16 (C9-C16), and isomers thereof. The process described herein is versatile and may be suitable for producing jet range hydrocarbons from many different grades and sources of triglycerides. Further, the process described herein may be selective to jet range hydrocarbons which may result in increased yield as compared to hydrocracking or other processes for producing jet range hydrocarbons from triglycerides.

Abstract: Systems and methods are provided for improving product yields and/or product quality during co-processing of fast pyrolysis oil in a fluid catalytic cracking (FCC) reaction environment. The systems and methods can allow for co-processing of an increased amount of fast pyrolysis oil while reducing or minimizing coke production for a feedstock including fast pyrolysis oil and a conventional FCC feed. The reducing or minimizing of coke production can be achieved in part by adding a low molecular weight, non-ionic surfactant to the mixture of fast pyrolysis oil and conventional FCC feed.

Abstract: A method for partitioning NMR T1-T2 data may comprise: identifying modes in NMR T1-T2 data from a plurality of samples with a multimodal deconvolution or decomposition with regularized nonlinear inversion; deriving a modal properties vector comprising modal properties for each of the modes; performing a cluster analysis of the modes to identify clusters; assigning a poro-fluid class to the clusters based on one or more of the modal properties of the modes in each of the clusters; and deriving partitioned representations for the clusters based on the cluster analysis.

Abstract: Systems and methods are provided for using a high heat capacity gas as at least a portion of the diluent during the regeneration step of a reverse flow reactor process. Instead of using nitrogen or air as the primary diluent gas, CO2 and/or H2O can be added as diluent gas for the regeneration step in the reaction cycle. Increasing the heat capacity of the diluent gas provides a reduction in the peak temperature within the reactor relative to the amount of fuel combusted during regeneration. This can allow for a reduction in the volume of diluent used during regeneration and/or an increase in the amount of fuel used. Reducing the volume of diluent can reduce the pressure drop during regeneration, which can provide a corresponding reduction in the amount of compression required for recycle of the diluent. Increasing the amount of fuel can allow for a corresponding increase in the amount of endothermic reaction performed during the reaction step.

Abstract: Methods for modeling subsurface formations may include: analyzing at least one strata within a stratigraphic structure of a formation to ascertain one or more physical properties for the at least one strata; correlating the one or more physical properties for the at least one strata to one or more formative hydraulic and sediment transport parameters for the at least one strata based on a correlation; modeling deposition of particulate matter during formation of the stratigraphic structure using a model constrained by the one or more formative hydraulic and sediment transport parameters to yield a three-dimensional model of the stratigraphic structure of the formation; and conditioning the three-dimensional model using the one or more physical properties for the at least one strata.

Abstract: This application relates to production of renewable fuels, including a method of producing renewable fuels. The method comprises hydrotreating a biofeedstock by contacting reactants comprising a combined feedstock and hydrogen with a hydrotreating catalyst to produce normal paraffins. The combined feedstock comprises a biofeedstock and an additional feedstock. The biofeedstock has about 10% or more of each of metals, phosphorous, and chlorophyll than the additional feedstock. The biofeedstock comprises the metals in an amount of about 300 parts per million (“ppm”) or less, the phosphorous in an amount of about 300 ppm or less, and the chlorophyll in an amount of about 50 ppm or less. The method further comprises isomerizing at least a portion of the normal paraffins to produce branched paraffins in an isomerization effluent.

Abstract: A quantitative simulation process for producing quantitative model predictions of hydrocarbon composition. The quantitative simulation may include measuring a chemical and isotopic composition of a hydrocarbon sample from a hydrocarbon reservoir. The quantitative simulation may further include measuring geochemical data, geophysical data, and/or geological data for the hydrocarbon reservoir and/or source rock; deriving temperature versus time relationships from a basin model for the hydrocarbon reservoir and/or source rock based on the geochemical data, geophysical data, and/or geological data; generating estimated source-rock maturity parameters based on the temperature versus time relationships; generating an estimated compositional yield for hydrocarbon fractions based on the temperature versus time relationships and the chemical composition of the hydrocarbon sample; and generating, using a mass-conserving isotopic fraction (MCIF) simulator, an estimated isotopic composition of the hydrocarbon fractions based on the estimated compositional yield and the isotopic composition of the hydrocarbon sample.

Abstract: A methodology for modeling oil/water or gas/water paleo zone reservoir properties for hydrocarbon management is provided. Reservoir simulations in a subsurface, such as in an oil region bounded by a gas cap and a water region, may use an initial reservoir simulation model. The methodology determines one or both of the oil/water or gas/water interfaces to honor the equilibrium state of the subsurface. The current configuration of the subsurface may be the result of one or more processes, such as a drainage process and an imbibition process, each of which have different associated curves reflecting the physical phenomena of the fluid/rock properties in the subsurface. The methodology honors the physical process, including comporting with the different curves and with the available data, in order to determine the current state of the subsurface, including one or both of the oil/water or gas/water interfaces.
