Methods, systems, devices and materials for producing biofuels under nanoscale control (“nanobiofuels”) are provided. In one aspect, the invention provides method for producing a biofuel, including providing a hydrocarbon producing organism; exposing the biological hydrocarbon producing organism to conditions effective to cause substantial release of the hydrocarbon from the biological hydrocarbon producing organism; and isolating at least a portion of the hydrocarbon. At least one of the actions of providing, exposing, and isolating is performed using a corresponding nanoscale control.

The invention relates to a continuous process for converting carbonaceous material contained in one or more feedstocks into a liquid hydrocarbon product, said feedstocks including the carbonaceous material being in a feed mixture including one or more fluids, said fluids including water and further liquid organic compounds at least partly produced by the process in a concentration of at least 1% by weight, where the process comprises converting at least part of the carbonaceous material by pressurizing the feed mixture to a pressure in the range 250-400 bar; heating the feed mixture to a temperature in the range 370-450° C., and maintaining said pressurized and heated feed mixture in the desired pressure and temperature ranges in a reaction zone for a predefined time; cooling the feed mixture to a temperature in the range 25-200° C. and expanding the feed mixture to a pressure in the range of 1-70 bar, thereby causing the carbonaceous material to be converted to a liquid hydrocarbon product and separating from the converted feed mixture a fraction comprising liquid hydrocarbon product.

A process for production of biofuels from algae can include cultivating an oil-producing algae by promoting sequential photoautotrophic and heterotrophic growth. The method can further include producing oil by heterotrophic growth of algae wherein the heterotrophic algae growth is achieved by introducing a sugar feed to the oil-producing algae. An algal oil can be extracted from the oil-producing algae, and can be converted to form biodiesel.

Systems and methods are provided for separating high value by-products, such as oil and/or germ, from grains used for alcohol production. In one embodiment, a method for separating by-products from grains used for alcohol production includes, subjecting milled grains to liquefaction to provide a liquefied starch solution including fiber, protein, and germ. The germ is separated from the liquefied starch solution. The separated germ is ground, e.g., to a particle size less than 50 microns, to release oil to provide a germ/oil mixture. Then, prior to fermentation, the oil is separated from the germ/oil mixture to yield an oil by-product. The pH of the germ/oil mixture can be adjusted to about 8 to about 10.5 and/or cell wall breaking enzymes or chemicals may be added to help release oil from the germ. In one example, the oil yield is greater than 1.0 lb/Bu.

The present invention relates to the co-production and isolation of mycoprotein and ethanol from carbohydrate feedstock material (e.g cereals). The present invention also provides a fermentation system for the co-production of mycoprotein from a carbohydrate feedstock material.

Ethanol is produced by the simultaneous production of both First and Second generation (1G, 2G) fuel grade ethanol in the same production plant. A First Generation feedstock such as corn is continuously fed to the first generation section and a lignocellulosic feedstock such as corn stover from the 1G corn is supplied to the second generation area Thus, there is a common fermentation area for both the C5 and C6 sugar fermentation. The invention can economically be best implemented in places where there are incentives offered for the use of various feedstocks. Specifically, the invention allows the D3 rin to be maximized in an existing first-generation ethanol plant with the installation of the front end of the 2G equipment.

A continuous process for the synthesis of biodiesel from microalgae oil by transesterification with supercritical methanol, where the synthesis of biodiesel is carried out in a single transesterification step in a reactor that operates continuously, said process being ideal to be carried out at industrial scale since it can provide a continuous flow of biodiesel.

The presently disclosed subject matter relates to an industrial system for processing various plant materials to produce marketable materials. Particularly, the system integrates subcritical water extraction technology and includes a pre-processing module and a two-stage extractor (processing module) with constant control of temperature, pressure, and/or residence time. In some embodiments, the final product of the disclosed system can include feedstock constituents for biofuel production (sugars and/or oil), biochar, raw materials for various industries (such as pulp for manufacturing paper or cellulose for use in various industries). The disclosed system can be modular or non-modular, stationary or mobile, and can include prefabricated elements with programmed automatic or manual operation so that it can be easily moved and/or assembled on site.

A process for the continuous production of lactic acid (a first fermentation product) and of a second fermentation product selected from the group consisting of alcohols and biogas, may include starting from the milling, necessarily carried out under dry conditions, of cereals and more particularly of corn. In the context of this process, a main flow and a flow of wastes which are difficult to ferment are recovered from the milling. These two flows are treated separately but simultaneously so as to produce, by fermentation, on the one hand, lactic acid and, on the other hand, an alcohol and/or biogas.

A system is for producing products, advantageously solvents, by fermentation, advantageously multi-stage fermentation. The fermentation is complemented with pervaporation as in situ product recovery technology, combined with a multistage condensation of the permeate. The condensates are separately introduced in the downstream processing of the system to recover the produced products, advantageously solvents. The system for producing products, advantageously solvents, by fermentation is simplified and has an overall improved energy efficiency, compared to systems described in the art.
