Abstract: Kerosene boiling range or jet fuel boiling range compositions are provided that are formed from crude oils with unexpected combinations of high naphthenes to aromatics weight and/or volume ratio and a low sulfur content. The resulting kerosene boiling range fractions can have an unexpected combination of a high naphthenes to aromatics weight ratio, a low but substantial aromatics content, and a low sulfur content. Such fractions can potentially be used as fuel after a reduced or minimized amount of additional refinery processing. By reducing, minimizing, or avoiding the amount of refinery processing needed to meet fuel and/or fuel blending product specifications, the fractions derived from the high naphthenes to aromatics ratio and low sulfur crudes can provide fuels and/or fuel blending products having a reduced or minimized carbon intensity.

Abstract: Marine diesel fuel/fuel blending component compositions and fuel oil/fuel blending component compositions are provided that are derived from crude oils having high naphthenes to aromatics volume and/or weight ratios and a low sulfur content. In addition to having a high naphthenes to aromatics ratio, a low sulfur content, and a low but substantial content of aromatics, such fuels and/or fuel blending components can have a reduced or minimized carbon intensity relative to fuels derived from conventional sources. The unexpected ratio of naphthenes to aromatics contributes to the fuels and/or fuel blending components further having additional unexpected properties, including low density, low kinematic viscosity, and/or high energy density.

Abstract: Method of refining whole crude oil or a wide cut crude oil, the methods comprising a combination of a hydrotreating reactor, a distillation tower, and an optional flash evaporation separator. The methods can also include light ends processing, fluid catalytic cracking, reforming, hydrocracking, and demetalization. In some methods a whole crude oil is first processed through a flash evaporation separator to create a wide cut crude oil and in other methods, the flash evaporation separator is not used as the whole crude oil is first treated in a hydrotreater.

Abstract: Provided are two-stage processes by which primary alcohols such as ethanol or 1-butanol are converted into distillate-range ethers and olefins utilizing Guerbet coupling followed by intermolecular dehydration. The ethers can be used, for example, as cetane-improvers in diesel fuel, while the olefins can be hydrogenated to afford paraffins.

Abstract: Systems and methods are provided for direct conversion of methane and/or ethane to methanol. The methods can include exposing methane to an oxidant, such as O2, in a solvent at conditions that are supercritical for the solvent while having a temperature of 310° C. or less, or about 300° C. or less, or about 290° C. or less. The solvent can correspond to an electron donor solvent that, when in a supercritical state, can complex with O2. By forming a complex with the O2, the supercritical electron donor solvent can facilitate conversion of alkane to methanol at short residence times while reducing or minimizing further oxidation of the methanol to other products.

Abstract: Provided is a method for determining air release performance of a lubricating oil. The method involves determining air release time of the lubricating oil in accordance with ASTM D3427 at a designated temperature; determining surface tension of the lubricating oil at the temperature used in ASTM D3427; determining kinematic viscosity of the lubricating oil in accordance with ASTM D445 at the temperature used in ASTM 3427; and utilizing the surface tension, ASTM D3427 air release time, and ASTM D445 kinematic viscosity to determine air release performance of the lubricating oil. Surface tension is correlated with ASTM D3427 air release time at an ASTM D445 kinematic viscosity of at least about 30 cSt. The method has higher measurement sensitivity and reproducibility/repeatability than ASTM D3427.

Abstract: Provided are octane enhancing additives and methods that improve a liquid fuel composition's octane rating. A liquid fuel composition may comprise a liquid fuel and an octane enhancing additive. The octane enhancing additive may comprise an indoline compound with a bicyclic ring structure, wherein the indoline compound comprises a six-membered aromatic ring and a five-membered aliphatic ring that share a carbon-carbon aromatic bond. The five-membered aliphatic ring may be heterocyclic and may comprise a nitrogen positioned in an alpha position to the six-membered aromatic ring.

Abstract: Systems and methods are provided for controlling the morphology of coke produced during delayed coking. The morphology control is achieved in part by introducing elemental sulfur into the coker feedstock prior to coking. The elemental sulfur can be introduced into the feed under conditions so that the sulfur is well-dispersed within the feed for a sufficient period of time. This can allow for relatively even reaction of sulfur with components throughout the feed, resulting in a relatively small, uniform domain size distribution for the coke produced during delayed coking. This coke can correspond to shot coke. By producing coke with a small and relatively uniform domain size distribution, the risk of uneven heating within the coke can be reduced or minimized.
