    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: A process for re-refining used lubricating oil (ULO), much of which is used motor oil (UMO) relies on more rapid heating, turbulent flows, higher peak temperatures, to achieve rapid thermal cracking, even including metal-bearing additives without catalysts, compared to conventional refining of crude oil and conventional recycling processing of UMO. By thermally cracking this way and scrubbing with recycled, processed liquids from the flow stream, a process readily removes metal-bearing hydrocarbons in typical lubricating oil additives. Those bonded metals consigned to heavy fraction “bottoms,” are commonly non-removable by other recycling schemes. Long chain polymers including paraffins are broken into lighter hydrocarbons with properties typical of fuels containing olefins, naphthenes, and the like. Data and analysis reveal low solids, effective metal removal, comparatively low viscosity and boiling points, and greatly reduced sulfur content in fuel and oil products resulting.

    Abstract: Provided is an n-heptane production method including: a step of distilling a feed containing C6−, C7, and C8+ hydrocarbon components, removing the C8+ and C6− hydrocarbon components, and separating the C7 hydrocarbon component; a step of adding the separated C7 hydrocarbon component to a hydrogenation apparatus and hydrogenating the separated C7 hydrocarbon component; a step of adding the hydrogenated C7 hydrocarbon component to a simulated moving bed (SMB) apparatus and separating the hydrogenated C7 hydrocarbon component into an extract containing n-heptane and a raffinate containing other components; and a step of distilling the extract and separating the n-heptane in an extract column, wherein a purity of the produced n-heptane is 98 wt % or higher.
