The present invention relates to agricultural practices for maximizing carbon sequestration, enhanced productivity, sustainable farming and minimizing greenhouse gas emissions. In one embodiment, there is provided a method comprising: planting a Brassica carinata variety as a second crop in rotation with a first crop or to replace fallow; implementing land management practices to reduce the use of fossil fuel inputs and to maximize the capture of atmospheric carbon by the plant material of Brassica carinata; harvesting of the Brassica carinata variety to obtain the grain; and returning about 70% to about 90% of all plant material from the Brassica carinata variety aside from the grain to the soil. As a result, the overall greenhouse gas emissions associated with agriculture are reduced. In some embodiments, the method further comprises producing grain for use in the production of a plant-based feedstock for producing low carbon intensity fuels; for adding carbon in soil; and/or acquiring a carbon credit.

The process produces a diesel from a biorenewable feedstock by hydrotreating to remove heteroatoms and saturate olefins. The biorenewable feedstock is contacted in a guard bed reactor in the presence of hydrogen to saturate olefins and remove metals to produce a contacted feed stream. The contacted feed stream is then heated in a charge heater to a higher temperature than in the guard bed reactor and hydrotreated in the presence of a hydrotreating hydrogen stream and a hydrotreating catalyst to deoxygenate the contacted feed stream to provide a hydrotreated stream.

The present invention provides a composition comprising 10-40 mass % of C.sub.8-30 linear alkanes, up to 20 mass % of C.sub.7-20 aromatic hydrocarbons, at least 90 mass % of which are monoaromatic, and no more than 1 mass % in total of oxygen-containing compounds; wherein the total amount of C.sub.8-30 alkanes in the composition is 50-95 mass %, and the total amount of C.sub.8-30 alkanes, C.sub.7-20 aromatic hydrocarbons and C.sub.8-30 cycloalkanes is at least 95 mass %; wherein the composition comprises 45-90 mass % in total of C.sub.8-30 cycloalkanes and C.sub.8-30 branched alkanes; and wherein the amounts are based on the mass of the composition. Also provided is a method of producing the composition comprising the step of hydroprocessing a biological feedstock using a catalyst and the step of fractionating the product of the hydroprocessing step.

The present disclosure is related to refining one or more grain oil composition streams (e.g., distillers corn oil or syrup) in a biorefinery to provide one or more refined grain oil products, where each grain oil product has targeted amounts of a free fatty acid component and the fatty acid alkyl ester component.

A composition of additives for fuel including: one or more copolymer(s) including:at least one unit of the following formula (I): wherein R1 is selected from hydrogen and methyl group, R2 is selected from C1 to C34 hydrocarbon-based chains, an aromatic ring, an aralkyl containing at least one aromatic ring and at least one C1-C34 alkyl group, andat least one unit of following formula (II): wherein R1 is selected from hydrogen and methyl group, Z is selected from the oxygen atom and NR group with R being selected from a hydrogen atom and C1 to C12 hydrocarbon-based chains, G includes a C1 to C34 hydrocarbon-based chain substituted with at least one quaternary ammonium group and optionally one or more hydroxyl groups, group G also possibly containing one or more nitrogen and/or oxygen atoms and/or carbonyl groups 25 at least one compound selected from succinimides substituted with a hydrocarbon-based chain.

A multipurpose fuel composition is disclosed which contains a petroleum derived jet fuel component and a renewable jet fuel component, wherein the multipurpose fuel composition has a freezing point of 40 C. or below, and an exemplary cetane number more than 40, preferably more than 45, more preferably more than 50.

The present disclosure relates to co-processing at least a fossil-based feed, pyrolysis liquid and a distillation residue from tall oil distillation in an oil refinery conversion process.

A method for producing a renewable base oil from a feedstock of biological origin includes providing a feedstock, the feedstock including: 2-95 wt % of a mixture of free fatty acids; 5-98 wt % fatty acid glycerols selected from mono-glycerides, di-glycerides and tri-glycerides of fatty acids; 0-50 wt % of one or more compounds selected from the list consisting of: fatty acid esters of the non-glycerol type, fatty amides and fatty alcohols; a major part of the feedstock being a mixture of free fatty acids and fatty acid glycerols; subjecting all or part of the feedstock to ketonisation reaction conditions where two free fatty acids react to yield a ketone stream, and subjecting the ketone stream to both hydrodeoxygenation and to hydroisomerisation reaction conditions, to yield a deoxygenated and isomerised base oil product stream containing the renewable base oil.

Hydrotreatment of biological oil is disclosed for producing renewable base oil and a diesel oil from low value biological oils. Low value biological oils containing free fatty acids and fatty acid esters can be processed into a renewable base oil and a renewable diesel oil in an efficient manner by first separating at least part of the free fatty acids from the feedstock and then processing separately this free acid feed in a ketonisation reaction followed by hydrodeoxygenation and hydroisomerisation reactions to yield a renewable base oil stream. The remaining free fatty acid depleted feed is processed in a separate hydrodeoxygenation and hydroisomerisation step to yield a renewable diesel stream.

A C.sub.31 renewable base oil is disclosed that is suitable as a base oil to provide low viscosity base oils, such as having both low Noack volatility and low CCS-30 C. viscosity and/or to provide low viscosity base oils at the same time having a combination of acceptable HTHS and KV100 to allow the industry's base oil blenders to formulate high quality engine oils, such as SAE grade 0W-20, 0W-16, 0W-12 or 0W-8.
