Abstract: A method of removing THC and/or THCA from a mixture is provided, the mixture including at least one other cannabinoid. The method comprises passing a first feedstock stream through a first chromatographic resin arranged in a simulated moving bed (SMB) chromatography configuration to provide a primary raffinate stream, preparing a second feedstock stream, the second feedstock stream comprising the primary raffinate stream or a concentrated primary raffinate stream, and passing the second feedstock stream through a second chromatographic resin to provide an eluate stream, the eluate stream having less than 0.3 wt % THC on a solvent free basis. The cannabinoid products can be used in various pharmaceutical and nutraceutical applications.
Abstract: A method for purification and separation of cannabinoids, such as cannabidiol and tetrahydrocannabinol, e.g., from dried hemp and cannabis leaves can use a continuous simulated moving bed process, a batch column chromatography method, or a single column, and a combination of one or more of a sequence of purification steps including: filtration, decolorization, activation or decarboxylation, dewaxing, polishing, and crystallization to separate a cannabinoid from the cannabis plant and to provide various cannabinoid products. The cannabinoid products can be used in various pharmaceutical and nutraceutical applications.
Abstract: A method of removing THC and THCA from a non-decarboxylated hemp extract, the non-decarboxylated hemp extract including THC and THCA and at least one cannabinoid is provided. The method comprises passing a first feedstock stream through a first chromatographic resin arranged in a simulated moving bed (SMB) chromatography configuration to provide a primary raffinate stream, preparing a second feedstock stream, the second feedstock stream comprising the primary raffinate stream or a concentrated primary raffinate stream, and passing the second feedstock stream through a second chromatographic resin to provide an eluate stream, the eluate stream having less than 0.1 wt % THC on a solvent free basis. The cannabinoid products can be used in various pharmaceutical and nutraceutical applications.
