Abstract: A process for the preparation of a granulated or pelletized weak anion exchange medium from a phenol-containing organic material like peat, followed by low-temperature torrefaction of the granules to produce a high degree of physical stability of the granules at high-pH conditions, followed by chemical pretreatment of the stable granule via a hydrolysis reaction, and optionally surface treatment with acids, followed by the main chemical treatment of the hydrolyzed granule via separate aldehyde and amine reagents, or alternatively via an adduct reagent like hexamethylenetetramine is provided by this invention. The weak anion exchange medium of this invention can be used in a variety of aqueous solution treatment processes, such as wastewater treatment for removing mineral acids like H2SO4, HNO3, HCl, HBr, HF, H3PO4, HI, or formic acid from the wastewater. The resulting anion exchanger medium is particularly useful for treating wastewaters in a low-pH environment.

Abstract: The invention provides improved processes for the extraction of betulin, lupeol, betulinic acid, suberinic acids, and/or other organic compounds and compositions from birch bark. In some embodiments, the birch bark can be physically processed prior to the extraction process, which can further improve the yield of the extraction. The bark processing can include, but is not limited to, one or more of pelletizing the bark, baling the bark, pucking the bark, or compressing the bark, to a form that is more dense per volume unit than prior to the processing.
