  • Process for treating biomass to produce materials useful for biofuels
    Patent number: 9873665
    Abstract: Since biomass is always accompanied by caustic inorganic materials, we have found that the formation of the anion salt of ?-hydroxysulfonic acid represent the largest “loss” of the ?-hydroxysulfonic acid in the potential reversible acid pretreatment process. By titrating the ?-hydroxysulfonic acid salt with strong mineral acid and then reverting the alfa-hydroxysulfonic acid as its primary components, the acid components can be recovered substantially quantitatively.
    Type: Grant

    Date of Patent: January 23, 2018
