Publication number: 20240124785Abstract: An improved method for removal of contaminants from low-value and waste fats and oils for the purpose of hydrodeoxygenation into diesel boiling range hydrocarbons. The method includes removing organically bound contaminants from fats, oils, and greases (FOG) by adding water to a contaminated FOG stream, subjecting the mixture to heat, and mixing to promote reaction between the water and the FOG. Then, separating a reacted FOG from the contaminants. The reacted FOG will result in reduced organically bound chlorine contaminants.Type: ApplicationFiled: June 9, 2023Publication date: April 18, 2024Applicant: Renewable Energy Group, Inc.Inventors: Martin Haverly, Ramin Abhari, David A. Slade, Jared Brown

Publication number: 20240124784Abstract: The present technology relates to biofuels, and more particularly, to biomass-based diesel from olefin oligomers. Diesel fuels with cetane number of 49 or greater are prepared by blending hydrocarbons produced by olefin oligomerization with renewable diesel, resulting in a blended fuel that has a lower cloud point than the cloud point of the renewable diesel. A different aspect relates to an integrated process for lipid HDO and olefin oligomerization wherein the propane coproduct of lipid HDO is subjected to dehydrogenation to produce a vapor stream having propylene and hydrogen. The propylene is subsequently oligomerized to iso-olefins and the iso-olefins are combined with the lipid feed for hydrogenation in the HDO reactor.Type: ApplicationFiled: October 2, 2023Publication date: April 18, 2024Applicant: Renewable Energy Group, Inc.Inventors: Ramin Abhari, Martin Haverly

Publication number: 20240124791Abstract: The invention relates to renewable hydrocarbons, and more particularly to biomass-based diesel fuel produced in a process including hydrodeoxygenation (HDO) of phenolic lipids. The process may generally include combining a phenolic lipid and a hydrocarbon diluent to provide a hydrocarbon-diluted phenolic lipid then subjecting the hydrocarbon-diluted phenolic lipid to hydrodeoxygenation in a reactor to provide a reactor effluent including a hydrodeoxygenated phenolic lipid. The hydrodeoxygenated phenolic lipid is separated from the reactor effluent.Type: ApplicationFiled: September 29, 2023Publication date: April 18, 2024Applicant: Renewable Energy Group, Inc.Inventors: Jared Brown, Ramin Abhari, Martin Haverly, David A.

Publication number: 20240076575Abstract: Methods and apparatus for economically producing a biodiesel product from feedstocks. Some embodiments comprise using at least one of a crude feedstock pretreatment process and a free fatty acid refining process prior to transesterification and the formation of crude biodiesel and glycerin. The free fatty acid refining process may include introducing the feedstock to glycerolysis to obtain a glycerolysis product then stripping the glycerolysis product to produce a fatty acid distillate and a stripped feedstock. The fatty acid distillate is recycled to the glycerolysis process to create more higher-molecular weight glycerides and the stripped feedstock (mostly di- and tri-glycerides) proceeds to transesterification to make biodiesel.Type: ApplicationFiled: August 23, 2023Publication date: March 7, 2024Applicant: Renewable Energy Group, Inc.Inventors: Martin Haverly, David A.

Publication number: 20230357648Abstract: A method for converting a bio-oil derived from lignocellulosic biomass to a fuel or fuel blendstock. The method may include contacting the bio-oil with a lipid or lipid derivative to form an organic phase comprising phenolic compounds and an aqueous phase. The organic phase is separated from the aqueous phase and subjected to hydrogenation and deoxygenation in a hydroprocessing reactor to produce a hydrocarbon product, a gas product, and water. The hydroprocessing reactor hydrocarbon product is fractionated into fuel products comprising gasoline and kerosene/diesel.Type: ApplicationFiled: May 5, 2023Publication date: November 9, 2023Applicant: Renewable Energy Group, IncInventors: David Slade, Ramin Abhari, Martin Haverly
