The present invention relates to a method for the valorization of gaseous effluents derived from alcoholic fermentation, comprising: a step of alcoholic fermentation in a bioreactor producing a fermented matter and a gaseous effluent, wherein the gaseous effluent comprises carbon dioxide; a step of extraction of the gaseous effluent from the bioreactor, followed by compression thereof, in order to obtain a compressed gaseous effluent; and a step of production of a suspension of alkaline bicarbonate in a bicarbonate production unit, wherein the bicarbonate production unit is divided into at least two compartments arranged successively in series. The present invention also relates to a corresponding plant.

Embeddable extensions of the functionality of email and calendaring applications are described herein. An originating email and calendaring application formats meeting items to include extensible content, e.g., within the body field of the meeting item. Recipient email and calendaring applications receive the meeting items and, depending on whether they are configured to provide an extended functionality, will either deploy the extensible content item according to the extended functionality or present the extensible content item according to a standardized functionality. The body field includes the extensible content item according to the standardized functionality that is interpretable by configured clients to provide the extended functionality.

A method of producing an aromatic chemical, comprises: providing a feedstock comprising biomass to a first reactor to produce a first product stream, wherein the first product stream comprises methane and carbon dioxide; combining the first product stream with a recycle stream to form a second reactor feed stream; passing the second reactor feed stream through a second reactor to produce a second product stream comprising aromatics and hydrogen gas; recovering aromatics from the second product stream to create a recovery stream depleted of aromatics; combining the recovery stream with a stream comprising carbon dioxide to form a combined recovery stream; passing the combined recovery stream to a third reactor to produce the recycle stream comprising gas; and forming an aromatic chemical from the second product stream.

A process comprising (i) providing a gaseous stream including greater than 1% by volume carbon dioxide; (ii) providing water; (iii) converting the carbon dioxide and the water to an organic intermediate and oxygen gas in the presence of light; (iv) separating the oxygen gas from the organic intermediate; and (v) converting the organic intermediate to ethylene and carbon dioxide after said step of separating the oxygen gas from the organic intermediate.

Processes and systems for recovering products from a corn fermentation mash. In one example, a process for recovering products from a corn fermentation mash can include separating ethanol from a fermentation mash to produce a whole stillage. The fermentation mash can be derived from a ground corn product milled from a plurality of corn pieces. The plurality of corn pieces can include whole corn kernels, fragmented corn kernels, size-reduced corn kernels, milled corn kernels, or a mixture thereof. Greater than 25 wt % of the ground corn product can have a particle size of greater than 105 μm and greater than 80 wt % of the ground corn product can have a particle size of 425 μm or less, as measured according to AOAC 965.22-1966. The process can also include separating the whole stillage to produce a fiber rich portion and a filtrate.
