The present invention relates to biofuels and, more particularly, to biomass-based diesel from olefin oligomers. Diesel fuel having a cetane number of 49 or greater is prepared by blending hydrocarbons resulting from olefin oligomerization with renewable diesel, resulting in a blended fuel having a cloud point lower than the cloud point of the renewable diesel. Various aspects relate to an integrated process for lipid HDO and olefin oligomerization in which the propane byproduct of the lipid HDO is dehydrogenated to produce a vapor stream having propylene and hydrogen. The propylene is then oligomerized to an isoolefin, and the isoolefin is combined with the lipid feed for hydrogenation in the HDO reactor.

A low-cost process is provided to render lignocellulosic biomass accessible to cellulase enzymes, to produce fermentable sugars. Some variations provide a process to produce ethanol from lignocellulosic biomass (such as sugarcane bagasse or corn stover), comprising introducing a lignocellulosic biomass feedstock to a single-stage digestor; exposing the feedstock to a reaction solution comprising steam or liquid hot water within the digestor, to solubilize the hemicellulose in a liquid phase and to provide a cellulose-rich solid phase; refining the cellulose-rich solid phase, together with the liquid phase, in a mechanical refiner, thereby providing a mixture of refined cellulose-rich solids and the liquid phase; enzymatically hydrolyzing the mixture in a hydrolysis reactor with cellulase enzymes, to generate fermentable sugars; and fermenting the fermentable sugars to produce ethanol. Many alternative process configurations are described. The disclosed processes may be employed for other fermentation products.

A method for providing a fuel includes removing hydrogen sulfide and/or carbon dioxide from biogas to provide partially purified biogas, which is filled in a mobile storage system. The partially purified biogas is transported to a centralized processing facility, in the mobile storage system, by truck, rail, or ship. At the centralized processing the partially purified biogas is further processed, either to produce a fuel that is renewable or has renewable content, or to produce renewable natural gas, which is used to produce the fuel that is renewable or has renewable content.

Provided herein is a genetically engineered microorganism comprising knock-in of DNA at an acetolactate decarboxylase gene locus. Replacement of the acetolactate decarboxylase gene with DNA encoding one or more native or nonnative enzymes confers certain advantages, including fermentation stability and increased production of native and nonnative products from gaseous substrates.

A safe and economical method for creating a solid fuel product from biomass-based materials. The method uses a horizontally oriented rotating pressure vehicle to essentially steam-cook the biomass-based materials over a period of time, slowly and safely releasing the steam after the process is complete.

A process for converting pomace derived from the production of fruit wine into a nutrient-rich food product, and a product made by said process. The process comprises milling the pomace, carrying out an anaerobic ethanolic fermentation in an anaerobic fermenter by adding yeast and optionally sugars to produce ethanol; carrying out an aerobic acetic acid fermentation in an aerobic fermenter by adding acetic acid bacteria to produce acetic acid, shearing the acetic acid pomace to produce a raw puree; and further processing the raw puree into a puree or powder. The process can be used to produce a product that qualifies for Kosher certification. The nutrient-rich product can be used as an ingredient in foods as a flavour, texture and color enhancer, to mask bitter flavours or off-notes, as a preservative, to fortify processed foods.

A method, system, and apparatus for decomposing a biomass feedstock include providing a layer of inert particulate matter, such as sand, to line and insulate the bottom surface of a main chamber of a reactor where pyrolysis and oxidation are conducted to produce char and producer gases as primary products. In an embodiment, feedstock positioned in a side region of the reaction chamber insulates side walls of the main chamber from heat in the center region of the main chamber. In an embodiment of the method, a rate of removal of solid products such as char from the reactor is controlled in response to a temperature detected at a position of an extraction tube inlet of the reactor. Activated charcoal may be obtained as a primary product using the system and method, by feeding oxygen into the reactor at an inlet positioned adjacent to an inlet to the extraction chamber.
