    Abstract: Provided are marine fuels or fuel blending compositions, methods of making such fuels or compositions and methods of potentially reducing the life cycle carbon intensity of marine fuels or a fuel blending compositions. The marine fuel or fuel blending composition disclosed herein includes at least 20 vol % of a resid-containing fraction, and from 5 vol % to 80 vol % of one or more renewable fuel blending components. The one or more renewable fuel blending components includes one or more fatty acid alkyl esters. Optionally the one or more renewable fuel blending components may include gas-to-liquid hydrocarbons from renewable synthesis gas, hydrotreated natural fat or oil, hydrotreated waste cooking oil, hydrotreated tall oil, pyrolysis gas oil, or combinations thereof. Optionally, the resulting marine fuel or fuel blending composition can have a BMCI−TE difference value of 15 or less.

    Abstract: A diesel fuel composition as disclosed includes a fossil diesel component, a fatty acid methyl esters component, and a hydrotreated renewable paraffinic diesel component. A method is disclosed for producing the diesel composition and use thereof. Use of the hydrotreated renewable paraffinic diesel component as an oxidation stability improver is further disclosed.

    Abstract: A reactor and process for the production of bio-diesel. The reactor includes one or more coiled reaction lines. The lines are positioned within a tank containing a heat transfer media such as molten salt, maintained at about 750° F. A pump circulates the media within the tank. An emulsion of alcohol; refined feed stock, including glycerides and/or fatty acids; and preferably water is pumped through the reaction lines at temperatures and pressures sufficient to maintain the alcohol in a super-critical state. The curvature of the coils, pump pulsing, and the flow rate of the emulsion keep the emulsion in a turbulent state while in the reactor, ensuring thorough mixing of the alcohol and feed stock. The alcohol reacts with the glycerides and fatty acids to form bio-diesel. The reaction is fast, efficient with regard to energy input and waste generation, and requires minimal alcohol.

    Abstract: Naphtha boiling range compositions are provided that can have improved combustion properties (relative to the research octane number of the composition) in spark ignition engines and/or compression ignition engines. The improved combustion properties can be achieved by controlling the total combined amounts of n-paraffins and isoparaffins that include a straight-chain propyl group (R1—CH2—CH2—CH2—R2). For such a straight-chain propyl group, R2 can correspond to any convenient CxHy group that can appear in a paraffin or isoparaffin. R1 can correspond to a hydrogen atom, making the straight-chain propyl group a terminal n-propyl group; or R1 can correspond to any convenient CxHy group that can appear in a paraffin or isoparaffin.
