Title:
METHOD OF PRODUCING GAMMA-BUTYROLACTONE FROM BIOMASS
Document Type and Number:
WIPO Patent Application WO/2023/191452
Kind Code:
A1
Abstract:
An improved method of producing gamma-butyrolactone (GBL) product with high purity in high yield from a starting biomass containing poly-4-hydroxybutyrate (P4HB) and water is disclosed. The method includes recycling a part of GBL product to replace the water to obtain a substantially water-free biomass slurry that is subjected to a conversion process to convert the P4HB to GBL.
