  • Methods for high yield production of furans from biomass sugars at mild operating conditions
    Patent number: 10351886
    Abstract: Facile methods for high-yield furfural and HMF production from biomass sugars are described. The methods generally involve converting the biomass sugars in high yield to their ketose isomers, resulting in furan production under low temperature and pressure conditions with efficient recycling of the process streams.
