A system and method for renewable diesel synthesis utilizes a triglyceride feedstock derived from biological sources. The first step involves hydrolysis of the triglycerides into an intermediate feedstock comprising a mixture of free fatty acids and glycerol (separated from the FFA by decantation and then distilled). The FFA is then further processed in a distillation step to produce a stream free of catalyst poisons and utilized as feedstock for hydrotreatment in a renewable diesel production process. By converting the initial triglyceride feedstock to an FFA feedstock, the need to hydrotreat at typical high temperature that promote the decarboxylation reaction is obviated, thereby reducing the production of CO2, generating a significantly higher proportion of saturated, long chain C14, C16 or C18 hydrocarbons (as opposed to short-chain carbons such as propane), and the more valuable glycerol product is secured.

The present invention relates to methods of producing industrial products from plant lipids, particularly from vegetative parts of plants. In particular, the present invention provides oil products such as biodiesel and synthetic diesel and processes for producing these, as well as plants having an increased level of one or more non-polar lipids such as triacylglycerols and an increased total non-polar lipid content. In one particular embodiment, the present invention relates to combinations of modifications in two or more of lipid handling enzymes, oil body proteins, decreased lipid catabolic enzymes and/or transcription factors regulating lipid biosynthesis to increase the level of one or more non-polar lipids and/or the total non-polar lipid content and/or mono-unsaturated fatty acid content in plants or any part thereof. In an embodiment, the present invention relates to a process for extracting lipids. In another embodiment, the lipid is converted to one or more hydrocarbon products in harvested plant vegetative parts to produce alkyl esters of the fatty acids which are suitable for use as a renewable biodiesel fuel.

The present invention generally relates to oil compositions and methods of producing such oil compositions. More particularly, the present invention relates to an oil composition recovered from a fermentation product as well as methods of recovering such oil compositions for use in various processes such as bio-diesel production as well as in various edible applications.

A process comprises feeding a stream of reactant compounds to a reactor and discharging a liquid plasma into the reactant stream in the reactor, wherein the plasma initiates or accelerates a reaction of the reactant compounds to form a product composition. The reactor can comprise one or more chambers, a high-voltage electrode positioned at a first portion of the one or more chambers, a ground electrode positioned at a second portion of the one or more chambers, and a dielectric plate between the ground electrode and the high-voltage electrode that comprises openings through which the reactant stream can pass from the first portion to the second portion or from the second portion to the first portion. Discharging the plasma can include supplying electrical power to the high-voltage electrode such that plasma is discharged where the reactant stream flows through the openings.

An unleaded gasoline composition comprises, based on the total volume of the unleaded gasoline composition, 50 to 96 vol. % of an unleaded gasoline; 2 to 20 vol. % of a mixed butanol; and 2 to 30 vol. % of a distillate oil fraction comprising a paraffin, an olefin, a naphthene, and an aromatic at an initial boiling point cut of 180° C., wherein the unleaded gasoline, the mixed butanol, and the distillate oil fraction are selected to provide the unleaded gasoline composition with a Research Octane Number of 90 to 101, determined in accordance with ASTM D 2699; and a Motor Octane Number of 81.4 to 90, determined in accordance with ASTM D 2700.

Systems and methods to provide low carbon intensity (CI) transportation fuels through one or more targeted reductions of carbon emissions based upon an analysis of carbon emissions associated with a combination of various options for feedstock procurement, feedstock refining, processing, or transformation, and fuel product distribution pathways to end users. Such options are selected to maintain the total CI (carbon emissions per unit energy) of the transportation fuel below a pre-selected threshold that defines an upper limit of CI for the transportation fuel.
