PROCESSES FOR CONVERTING BIOMASS INTO HIGH-VALUE PRODUCTS

Resumen de: US20260265674A1

A method for extracting carboxylic acids from an aqueous fermentation broth is disclosed. The method involves first contacting the broth with carbon dioxide under pressure to acidify the mixture.

In other embodiments, heat or gas stripping is applied to release the free carboxylic acid and regenerate the extractant for recycling. The process may be enhanced by using membrane-based liquid-liquid contactors.
