- Illustrative diesel fuels useful in this disclosure include, for example, fossil diesel, petroleum diesel, synthetic diesel, biodiesel, renewable diesel, hydrogenated oils and fats, dimethyl ether (DME), and the like.
- Petroleum diesel or fossil diesel is produced from the fractional distillation of crude oil at a temperature between 200°C and 350°C and at atmospheric pressure, resulting in a mixture of carbon chains that typically contain between about 9 about 25 carbon atoms per molecule.
- Synthetic diesel is produced from any carbonaceous material, including biomass, biogas, natural gas, coal and others.
- the raw material is gasified into synthesis gas, which after purification is converted by the Fischer-Tropsch process to a synthetic fuel.
- the process is typically referred to as biomass-to-liquid (BTL), gas-to-liquid (GTL) or coal- to-liquid (CTL) depending on the raw material used.
- Paraffinic synthetic diesel generally has a near-zero content of sulfur and very low aromatics content, reducing unregulated emissions of toxic hydrocarbons, nitrous oxides, and particulate matter (PM).
- E-diesel is a synthetic diesel fuel created from carbon dioxide, water, and electricity with a process powered by renewable energy sources to create a liquid energy carrier which is refined to generate e-diesel.
- Acetals can be made as an e-fuel or syn fuel where they are made from captured CO2 and renewable electricity derived hydrogen (e.g., via water electrolysis or via steam reforming with a carbon capture step). See, for example, Ind. Eng. Chem. Res. 2019, 58, 14, 5567-5578 and https://pubs.acs.org/doi/pdf/10.1021/acs.iecr.8b05577 describing the production of oxymethylene dimethyl ethers (OME3-5) from hydrogen and carbon dioxide. See also the life cycle assessment of OME3-5 synfuel production from this study at DOI: https://doi.org/! 0.1039/C9SE00658C.
- OME3-5 oxymethylene dimethyl ethers
- Molecules such as dibutoxymethane can be made via trans acetalization reaction of OME where the larger alcohol such as ethanol and 1 -butanol can be bio-sourced through fermentative pathways, leading to production of low emission fuel.
- OME Organic Chemical Vapor
- the larger alcohol such as ethanol and 1 -butanol
- fermentative pathways leading to production of low emission fuel.
- Biodiesel is obtained from vegetable oil or animal fats (biolipids) which are mainly fatty acid methyl esters (FAME), and transesterified with methanol.
- Biodiesel can be produced from many types of oils, the most common being rapeseed oil (rapeseed methyl ester, RME) in Europe and soybean oil (soy methyl ester, SME) in the U.S. Methanol can also be replaced with ethanol for the transesterification process, which results in the production of ethyl esters.
- the transesterification processes use catalysts, such as sodium or potassium hydroxide, to convert vegetable oil and methanol into biodiesel and the undesirable byproducts glycerine and water, which need to be removed from the fuel along with methanol traces.
- catalysts such as sodium or potassium hydroxide
- Biodiesel can be used pure in engines where the manufacturer approves such use, but it is more often used as a mixture.
- Biodiesel useful in this disclosure can be derived from biological sources such as vegetable, animal, fish, and/or algae.
- vegetable fats/oils refer generally to any plant based material, and can include fat/oils derived from a source such as plants of the genus Jatropha.
- the biological sources can include vegetable fats/oils, animal fats/oils, fish oils, pyrolysis oils, and algae lipids/oils, and in some embodiments can specifically include one or more type of lipid compounds.
- Lipid compounds are typically biological compounds that are insoluble in water, but soluble in nonpolar (or fat) solvents. Non-limiting examples of such solvents include alcohols, ethers, chloroform, alkyl acetates, benzene, and combinations thereof.
- lipids include, but are not necessarily limited to, fatty acids, glycerol-derived lipids (including fats, oils and phospholipids), sphingosine-derived lipids (including ceramides, cerebrosides, gangliosides, and sphingomyelins), steroids and their derivatives, terpenes and their derivatives, fat-soluble vitamins, certain aromatic compounds, and long-chain alcohols and waxes.
- lipids In living organisms, lipids generally serve as the basis for cell membranes and as a form of fuel storage. Lipids can also be found conjugated with proteins or carbohydrates, such as in the form of lipoproteins and lipopolysaccharides.
- vegetable oils examples include, but are not limited to rapeseed (canola) oil, soybean oil, coconut oil, sunflower oil, palm oil, palm kernel oil, peanut oil, linseed oil, tall oil, corn oil, castor oil, jatropha oil, jojoba oil, olive oil, flaxseed oil, camelina oil, safflower oil, babassu oil, tallow oil, and rice bran oil.
- Vegetable oils as referred to herein can also include processed vegetable oil material.
- Non-limiting examples of processed vegetable oil material include fatty acids and fatty acid alkyl esters.
- Alkyl esters typically include C1-C5 alkyl esters.
- animal fats that can be used in accordance with the disclosure include, but are not limited to, beef fat (tallow), hog fat (lard), turkey fat, fish fat/oil, and chicken fat.
- the animal fats can be obtained from any suitable source including restaurants and meat production facilities.

- Alkyl esters typically include C1-C alkyl esters. One or more of methyl, ethyl, and propyl esters are preferred.
- Algae oils or lipids are typically contained in algae in the form of membrane components, storage products, and metabolites. Certain algal strains, particularly microalgae such as diatoms and cyanobacteria, contain proportionally high levels of lipids. Algal sources for the algae oils can contain varying amounts, e.g., from 2 wt % to 40 wt % of lipids, based on total weight of the biomass itself.

- OME3-5 oxymethylene ether mixture
- a method for reducing one or more of criteria emissions and greenhouse gas emissions of a diesel combustion engine comprising: introducing a diesel fuel composition into a fuel supply for the diesel combustion engine, and combusting the diesel fuel composition in the diesel combustion engine; wherein the diesel fuel composition comprises a diesel fuel blended with a diesel fuel blending component; wherein the diesel fuel blending component comprises one or more C8-C12 ethers, wherein the one or more C8-C12 ethers are represented by the formula
- R 3 and R4 are the same or different and are an alkyl group having from about 4 to about 6 carbon atoms; and wherein the diesel fuel composition, when combusted in the diesel combustion engine, reduces one or more of criteria emissions and greenhouse gas emissions of the diesel combustion engine, as compared to one or more of criteria emissions and greenhouse gas emissions produced using an otherwise identical diesel fuel composition without the diesel fuel blending component.
- ranges from any lower limit can be combined with any upper limit to recite a range not explicitly recited, as well as, ranges from any lower limit can be combined with any other lower limit to recite a range not explicitly recited, in the same way, ranges from any upper limit can be combined with any other upper limit to recite a range not explicitly recited.
- Every point or individual value can serve as its own lower or upper limit combined with any other point or individual value or any other lower or upper limit, to recite a range not explicitly recited.

Abstract
La présente divulgation concerne une composition de carburant diesel comprenant : (i) un carburant diesel ; et (ii) un constituant de mélange de carburant diesel comprenant un ou plusieurs acétals (par exemple, un acétal en C9, à savoir le dibutoxyméthane (DBM), ou un ou plusieurs éthers en C8 à C12 (par exemple, un éther en C10, à savoir l'éther d'isoamyle (Isame)). Le constituant de mélange de carburant diesel est mélangé avec le carburant diesel pour former la composition de carburant diesel. La composition de carburant diesel, lorsqu'elle fait l'objet d'une combustion dans un moteur à combustion diesel, réduit un ou plusieurs éléments parmi des émissions ciblées et des émissions de gaz à effet de serre du moteur à combustion diesel, par comparaison avec un ou plusieurs éléments parmi des émissions ciblées et des émissions de gaz à effet de serre produites au moyen d'une composition de carburant diesel identique mais ne contenant pas le constituant de mélange de carburant diesel. La présente divulgation concerne également un procédé permettant de réduire un ou plusieurs éléments parmi des émissions ciblées et des émissions de gaz à effet de serre d'un moteur à combustion diesel.
