Hydrothermal liquefaction of lignocellulosic biomass to bio-oils with controlled molecular weights

The disclosed invention is a process for liquefaction of hydrolysis residue of lignocellulosic biomass, original lignocellulosic biomass or municipal solid waste in alcohol-water media at alkaline conditions, for the production of low-M.sub.w bio-oils. The disclosed process is characterized in that it works for the direct liquefaction of the biomass, and operates under mild conditions (<300 C. and <10 MPa) employing alkali compounds as catalysts (NaOH, KOH, CaO, Na.sub.2CO.sub.3, K.sub.2CO.sub.3, Ca(OH).sub.2 or Ba(OH).sub.2). The process is further characterized in that it employs mixed solvents (glycerol-water, ethylene-glycol, water, glycerol-alcohol-water or ethylene-glycol-alcohol water), where all solvents are recyclable and reusable. The low-Mw bio-oils from hydrolysis residue of lignocellulosic biomass, original lignocellulosic biomass or municipal solid waste can be utilized as a liquid bio-fuel or bio-based chemicals for the production of various bio-based materials.

System and method for filtering organic compounds
10894224 · 2021-01-19 ·

A system and method for removing undesirable organic compounds so that the desirable cannabinoids, terpenes, and any other beneficial organic compounds can be easily and effectively captured is provided herein. The system and method makes use of diatomaceous earth filters through which a solution containing the organic compounds is rinsed with liquid non-polar solvent. The undesirable components remain in the diatomaceous while the beneficial organic compounds pass through and are collected in a liquid solution.

PROCESS FOR SEPARATING A CONSTITUENT/CANNABINOID USING A CHROMATOGRAPHIC RESIN

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.

Mobile Crop Processing System and Method
20200392059 · 2020-12-17 · ·

A mobile crop processing system includes a self-propelled harvester that shears and chops plant material, a mobile extraction assembly that follows the harvester and receives the chopped plant material to produce a crude oil output while discarding unwanted moisture and biomass in the field, a field-based extraction assembly that separates the crude oil into reclaimed solvent and essential oil, and a transporter for carrying containers of crude oil and solvent between the mobile and field-based extraction assemblies. The mobile extraction assembly includes a pre-treatment assembly for mixing plant material with solvent, a dewatering and maceration assembly for removing moisture from the plant material, and a separation assembly for removing additional moisture and biomass. Using the system, crops can be harvested and processed in the field when they are ready to be cut. The system can operate continuously until a desired portion of the field has been cut and processed.

Cannabidiol isolate production systems and methods

The disclosure includes systems and methods of producing cannabidiol (CBD) isolate. In some embodiments, a method includes dissolving, via an agitated vessel, CBD oil in a solvent to thereby form a slurry comprising CBD isolate and excess solvent, and sending at least a portion of the slurry from the agitated vessel to an agitated Nutsche filter dryer. Some embodiments include pressurizing an internal portion of the agitated Nutsche filter dryer to remove the excess solvent and capture the CBD isolate in a filter of the agitated Nutsche filter dryer.

Method for extracting compositions from plants

Methods for extracting and concentrating cannabinoids using ultrasound-enhanced solvent extraction. Freshly harvested cannabis plant materials, which may be selectively chosen plant parts or the entire plant itself, are shredded to a particular particle size. The plant material is then mixed with a solvent to form a slurry, and thereafter subjected to ultrasound to release intracellular contents into the solvent. Filtering steps are then applied to remove biomass, waxes and chlorophyll. Water removal and solvent recovery steps are further applied to ultimately derive an extract having high concentrations of target cannabinoids, and in particular cannabidiol (CBD). The methods may be deployed on-site in batch or continuous flow processes, and may further be utilized to derive other types of materials from plants, such as essential oils.
