ULTRA LOW SULFUR MARINE FUEL COMPOSITIONS

Hydroprocessed residual fuel and/or fuel blending components are provided that have a sulfur and nitrogen level comparable to liquefied natural gas (LNG). Because of the low starting level of sulfur and/or nitrogen, the severity of the hydroprocessing that is needed for the crude oil or bottoms fraction in order to remove sulfur to a level that is comparable to LNG is reduced or minimized. This can allow the resulting marine residual fuels to have low carbon intensity, low SOx and NOx emission and high energy density. Since the hydroprocessed fractions correspond to a fuel oil product, the resulting marine fuel can be used in existing fleets, and can be distributed in existing bunkering systems.

HIGH NAPTHENIC CONTENT DISTILLATE FUEL COMPOSITIONS

Distillate boiling range and/or diesel 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. This unexpected combination of properties is characteristic of crude oils that can be fractionated to form distillate/diesel boiling range compositions that can be used as fuels/fuel blending products with reduced or minimized processing. The resulting distillate boiling range fractions and/or diesel boiling range fractions can have an unexpected combination of a high naphthenes to aromatics weight and/or volume ratio, a low but substantial aromatics content, and a low sulfur content. By reducing, minimizing, or avoiding the amount of hydroprocessing 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.

Solvent and Temperature Assisted Dissolution of Solids from Steam Cracked Tar

Processes for preparing a low particulate liquid hydrocarbon product are provided and include blending a tar stream containing particles with a fluid and heating to a temperature of 250° C. or greater to produce a fluid-feed mixture that contains tar, the particles, and the fluid. The fluid-feed mixture contains about 20 wt % or greater of the fluid, based on a combined weight of the tar stream and the fluid. Also, about 25 wt % to about 99 wt % of the particles in the tar stream are dissolved or decomposed when producing the fluid-feed mixture.

Catalytic stripping process

Method of Treating Pyrolysis Oil From Waste Plastics

The present disclosure provides a method of treating waste plastic pyrolysis oil. The method includes a first step of washing waste plastic pyrolysis oil with water and then removing moisture; a second step of mixing the waste plastic pyrolysis oil from which the moisture is removed and a sulfur source to prepare a mixed oil; a third step of hydrotreating the mixed oil with hydrogen gas in the presence of a hydrotreating catalyst; a fourth step of separating the hydrotreated mixed oil into a liquid stream and a gas stream to obtain liquid pyrolysis oil; and a fifth step of recovering hydrogen gas from the separated gas stream and recycling the recovered hydrogen gas to the third step.
