Abstract
A process for producing products from biomass comprising fermenting biomass to produce a first product stream comprising carboxylic acid salts; acidifying at least one of the first product stream and a second product stream to produce a third product stream comprising acids; extracting such acids from the third product stream with a solvent; separating the extracting solvent from the acids to produce the separated extracting solvent and a fourth product stream comprising acids; and processing the fourth product stream to produce a fifth product stream.
Claims23
A process for producing products from biomass comprising:
- fermenting biomass to produce a first product stream comprising carboxylic acid salts;
- acidifying at least one of the first product stream, a second product stream, and combinations thereof to produce a third product stream comprising acids;
- extracting acids from the third product stream with a solvent, and subsequently separating the solvent from the acids to produce separated solvent and a fourth product stream comprising acids;
- processing the fourth product stream to produce a fifth product stream;
- and
- recycling at least a portion of the fourth product stream or the fifth product stream for use as at least part of the solvent.
A process for producing products from biomass comprising:
- fermenting biomass to produce a first product stream comprising carboxylic acid salts;
- producing acids from the first product stream, a second product stream, and combinations thereof, to form a third product stream;
- extracting acids from the third product stream with a solvent, and separating the solvent from the acids to produce separated solvent and a fourth product stream comprising acids;
- processing the fourth product stream to produce a fifth product stream;
- and
- recycling at least a portion of the fifth product stream to act as the solvent.
A process for producing medium-chain fatty acids from biomass comprising:
- fermenting biomass to produce a first product stream comprising short- and medium-chain fatty acid salts;
- acidifying at least one of the first product stream, a second product stream, and combinations thereof to produce a third product stream comprising acids;
- allowing the third product stream to phase separate into an organic phase and an aqueous phase;
- and
- recovering medium-chain fatty acids from the organic phase.
