A system and method of producing synthesis gas and bio-oil from biomass. The method comprises producing, in a gasification unit, synthesis gas from a carbonaceous feedstock, optionally cooling the synthesis gas discharged from the gasification unit, channeling the synthesis gas towards a hydrothermal processing unit, wherein the hydrothermal processing unit is configured to process a biomass feedstock contained in a pressurized water stream, transferring, in the hydrothermal processing unit, heat from the synthesis gas to the biomass feedstock, and producing a hydrothermal product from the biomass feedstock in the pressurized water stream.

This disclosure describes techniques for using a single feedstock of barley to produce a fermented product and a method for filtering a large-particles stream from a liquid stream containing small particles of a process stream using a series of mechanical separation devices to increase yield.

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.

A method and system are disclosed for producing a zein protein product from a whole stillage byproduct produced in a corn (or similar carbohydrate-containing grain) dry-milling process for making alcohol, such as ethanol, and/or other biofuels/biochemicals. In one embodiment, the method includes separating the whole stillage byproduct into an insoluble solids portion and a centrate (solubles) portion, which includes protein, such as zein protein. Thereafter, the centrate (solubles) portion can be separated into a water soluble solids portion and a protein portion, which includes zein protein. Zein protein may be separated out from the protein portion. The remaining protein portion may be further processed to produce a high protein corn meal. The resulting zein protein portion may be further processed to be sold as a zein protein product and/or used as or in, for example, coatings, fibers, adhesives, ceramics, inks, cosmetics, textiles, food products, pharmaceutical, and biodegradable plastics.

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.
