The present disclosure provides a process for forming a biogenic carbon-based fuel or a fuel intermediate from biogenic carbon dioxide and hydrogen. The hydrogen is sourced from a process that produces hydrogen and fossil carbon dioxide from a fossil-fuel hydrocarbon and separates the fossil carbon dioxide from the hydrogen. The process may further comprise carrying out or arranging for one or more parties to carry out at least one step that contributes to a reduction in the GHG emissions of the biogenic carbon-based fuel, or a fuel made from the fuel intermediate, of at least 20% relative to a gasoline baseline. In various embodiments this includes (a) introducing the fossil carbon dioxide underground, and/or (b) using a biogenic carbon-based product selected from a chemical and energy product produced from the non-fossil organic material to displace the use or production of a corresponding fossil-based product.

A process is provided for forming a fuel or a fuel intermediate from two fermentations that includes feeding an aqueous solution comprising a fermentation product from a first bioreactor to a second bioreactor and/or a stage upstream of the second bioreactor, which also produces the fermentation product. The aqueous solution may be added at any stage of the second fermentation and/or processing steps upstream from the second bioreactor that would otherwise require the addition of water. Accordingly, the product yield is increased while fresh/treated water usage is decreased.

Biomass feedstocks (e.g., plant biomass, animal biomass, and municipal waste biomass) are processed to produce useful products, such as fuels. For example, systems are described that can convert feedstock materials to a sugar solution, which can then be fermented to produce ethanol. Biomass feedstock is saccharified in a vessel by operation of a jet mixer, the vessel also containing a liquid medium and a saccharifying agent.

A crystalline pigment or colorant composition having high color intensity and/or low sugar content, and methods and processes of preparation. The composition may comprise purified fruit and/or vegetable color juices.

A device for refining ethanol is disclosed, which includes a fermentation unit, a low-pressure column, a medium-pressure column, a high-pressure column and a membrane separation unit. A method for refining ethanol is disclosed, which specifically includes the following steps: after fermenting the biomass feedstock, feeding fermented mash into a low-pressure column and a high-pressure column which are connected in parallel for refining, mixing two column top distillates, and feeding the mixed column top distillates into a medium-pressure column for further rectification; and purifying the refined ethanol vapor with higher purity obtained after rectification in the medium-pressure column by a membrane separation unit to obtain high-concentration ethanol product vapor. The disclosure couples the differential pressure rectification and the membrane separation unit, adjusts the energy network structure, greatly reduces the vapor usage amount of the whole system, and has the advantages of good separation effect, high product quality and the like.
