A smokable product is an organolepticly homogenous smokable material comprising shredded hemp paper that has been treated with a solution of cannabinoids and terpenes, and a wrapping paper to hold the smokable material in a rolled form. A method includes grinding cannabis plants, removing terpenes and cannabinoids from the cannabis plants, leaving cannabis fibers, pulping the cannabis fibers to produce hemp paper, shredding the hemp paper to produce shredded paper, combining at least the terpenes and cannabinoids into a solution based upon a predetermined formula, spraying the shredded paper with the solution to produce smokable material, and rolling the smokable material into a cigarette.

A process for producing an aroma-laden gas (10) comprises the following steps: a) providing a liquid phase (5), which contains a solvent and one or several aromatic substances (1, 2, 3); b) guiding through a solid phase extraction column (3) of the liquid phase provided in step (a) by obtaining the solid phase (35) laden with one or several aromatic substances; separating one or several aromatic substances from the laden solid phase by means of at least one gas (2) in a liquid and/or supercritical state; and optionally d) collecting the gas (10), which is laden with one or several aromatic substances (1, 2, 3).

A method for separating and recovering compounds from biomass is provided. In the method, an aqueous extraction fluid in essentially gaseous phase, such as steam, is propagated through a reaction area containing biomass feedstock. When extraction fluid advances through the biomass feedstock, in predetermined reaction conditions, a target compound separates from the essentially solid feedstock matter and travels, with the extraction fluid, towards the end of the reaction area, in where the target compound is recovered in the form of an essentially liquid medium. The method is beneficial for extracting long-chain hemicelluloses from cellulose-containing feedstocks.

An apparatus and method for extraction of oils from botanical material using high-pressure hydrocarbons such as propane, or butane, or mixtures thereof are described. A high-pressure propane or butane saturated liquid/vapor mixture formed by pressure reduction through a valve placed before an extraction column, thereby serving as an expansion port was employed. The apparatus is capable of both continuous liquid extraction or batch-style liquid operation through the use of a manifold valve, which directs the solvent liquid/vapor in the system to either a supply tank or an extraction column.

Electric jacket systems and methods for extraction are described. A system may be arranged or arrangeable for electrically controlling a temperature of one or more extraction system components. The system may include a first plurality of thermoelectric devices, the first plurality arranged or arrangeable for coupling with a first extraction system component at multiple locations along the first extraction system component. The system may further include a controller operably coupled to the first plurality of thermoelectric devices, with the controller configured or configurable to establish or maintain at least a first target temperature by selectively applying or causing the selective application of electrical power to the first plurality of thermoelectric devices.

The invention relates to a method of separation by fractionalization of the antioxidant active ingredients of Rosemary plant, which are the diterpenes Carnosic acid and Camosol and the phenolic acid Rosmarinic Acid, through column chromatography method. The production process involves the passage of rosemary extract, which is obtained in/with a proper solvent, through a column packed with a suitable packing material, the separation of the part rich in carnosic acid and carnosol, and the obtainment of a deodorized product in powder form after drying. During the process, another extract containing rosmarinic acid with high antioxidant activity is also obtained. The invention thus allows the use of an extract rich in carnosic acid and carnosol and another extract containing rosmarinic acid—which are obtained at once with no need for additional processes like acidification, precipitation, membrane filtration or deodorization—in food, pharmaceutical and cosmetic sector applications.

Disclosed are extraction solvents used in compositions and methods to refine synthetic feedstocks derived from plastic. Methods of refining plastic-derived synthetic feedstocks are also provided. For example, a method of refining a plastic-derived synthetic feedstock composition may include adding an extraction solvent to a synthetic feedstock composition derived from plastic pyrolyis to provide an extract phase and a raffinate phase, wherein the extraction solvent includes a polar organic extraction solvent immiscible in the synthetic feedstock. The methods may also include separating the raffinate phase from the extract phase to obtain a refined synthetic feedstock.

An arrangement of a mobile harvester decarboxylator with a terpene collector includes a heated enclosure for use in the field with terpene collectors coupled to ducted fume hoods of the heated enclosure. The terpene collector may include a chilled coil that condenses and separates oil-based terpenes from water-based terpenes via a centrifugal effect and/or immiscibility.

The present disclosure relates to a metal recovery process comprising a solvent extraction process. In an exemplary embodiment, the solution extraction system comprises a plant with a first and second circuit. A high-grade pregnant leach solution (“HGPLS”) is provided to the first and second circuit, and a low-grade pregnant leach solution (“LGPLS”) is provided to the second circuit. The first circuit produces a rich electrolyte, which can be forwarded to a primary metal recovery, and a low-grade raffinate, which can be forwarded to a secondary metal recovery process. The second circuit produces a rich electrolyte, which can also be forwarded to the primary metal recovery process. The first and second circuits are in fluid communication with each other.

A process is disclosed for extracting cannabinoids from plant materials. The process comprises providing a pressurizable extraction vessel having a rotatable drum with baffles, along with providing a solvent permeable filter bag. The plant material is placed within the filter bag, and the filter bag containing the plant material is placed within the extraction vessel. The extraction vessel is then filled with subcritical liquid carbon dioxide and rotated to so that the plant material is in contact with the liquid carbon dioxide. After a selected period of time, the liquid carbon dioxide solvent containing the cannabinoid extracted from the plant material is removed from the vessel, and sent to a separator. The separator separates the cannabinoid from the liquid carbon dioxide solvent.
