Abstract: Systems and methods to reduce pour point (PP) temperatures of fat-based compositions for use in transportation fuels. In one or more embodiments, methods and systems reduce the pour point of rendered fats using biologically-derived plant oils for effectively transporting the blended fat based compositions over long distances, thereby advantageously decreasing the heating and mixing requirements needed to maintain the compositional temperature above the pour point. In certain embodiments, the fat based composition comprises rendered animal fats, such as tallow in combination with distilled corn oil (DCO).

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: The invention discloses a method for producing bio-fuel (BF) from a high-viscosity biomass using thermo-chemical conversion of the biomass in a production line (10) with pumping means (PM), heating means (HM) and cooling means (CM). The method has the steps of 1) operating the pumping means, the heating means and the cooling means so that the production line is under supercritical fluid conditions (SCF) to induce biomass conversion in a conversion zone (CZ) within the production line, and 2) operating the pumping means so that at least part of the production line is in an oscillatory flow (OF) mode. The invention is advantageous for providing an improved method for producing biofuel from a high-viscosity biomass. This is performed by an advantageous combination of two operating modes: supercritical fluid (SCF) conditions and oscillatory flow (OF).

Abstract: A method for providing a fuel includes providing a partially purified biogas at a first processing site, where the partially purified biogas is produced by multiple biogas sources and/or from multiple feedstock sources. The partially purified biogas is compressed, fed to a mobile tank, and transported by vehicle to a second processing site. At the second processing site, which may also receive biogas from a plurality of biogas sources, the partially purified biogas is further processed to produce a fuel or fuel intermediate.

Abstract: A gasoline fuel composition for a spark ignition internal combustion engine comprising (a) gasoline blending components, (b) renewable naphtha at a level of 10 to 30% v/v and (c) oxygenated hydrocarbon at a level of 20% v/v or less, wherein the gasoline blending components comprise (a) 0-30% v/v alkylate, (b) from 0 to 15% v/v isomerate; (c) 0 to 20% v/v catalytic cracked tops naphtha; and (d) 20% to 40% v/v of heavy reformate, wherein the total amount of alkylate, isomerate, catalytic cracked tops naphtha and heavy reformate is at least 50% v/v based on the total fuel composition, and wherein the gasoline fuel composition meets the EN228 specification. While the low octane number of renewable naphtha would normally severely restrict its blendability in gasoline to low levels, it has now been found that renewable naphtha can be included in, for example, ethanol-containing gasoline fuel compositions, in surprisingly and significantly high blend ratios of renewable naphtha to ethanol.
