The present invention relates to the use of a composition containing 1,8-para-menthenethiol and 3-mercaptohexyl acetate, such as a plant extract and in particular an extract of timur (Zanthoxylum armatum), as odor-masking agent. It also relates to a deodorizing product in the form of an aerosol, candle, or electrical or wick fragrance diffuser, containing this composition.

Provided is a component extraction device for eluting a component in a sample into a supercritical fluid to extract the component from the sample. The component extraction device includes: a container rack including a plurality of sample container holding parts; a rack mounting stand including a mounting section on which the container rack is mounted; a plurality of heating blocks fixedly disposed on a mounting face of the mounting section at positions respectively corresponding to the plurality of sample container holding parts; a plurality of temperature sensors each configured to detect a temperature of each of the plurality of heating blocks; and a control unit configured to respectively control the plurality of heating blocks, based on results of detection by the plurality of temperature sensors.

The present invention generally relates to a method of reducing contamination from plastics. The resulting purer plastic can be used in demanding applications.

Abstract: Described herein is a process for obtaining rare earth elements from coal-based resources. Advantages of this process include low energy demands, application of environmentally-friendly solvents, and high purities of obtained rare earth elements.

Methods and apparatus for cryo-curing plants are disclosed herein, which allow the plant to be picked and ready for sale and use within days. When the plant is cannabis, the process can deliver a product having a desired moisture content and limited loss of terpenes in just 24 to 48 hours.

Textile compositions comprising at least one filamentous fungus are disclosed, as are methods for making and using such textile compositions. Embodiments of the textile compositions generally include at least one of a plasticizer, a polymer, and a crosslinker, in addition to the filamentous fungus. The disclosed textile compositions are particularly useful as analogs or substitutes for conventional textile compositions, including but not limited to leather.

Methods and apparatus consistent with the present disclosure may provide electrical energy and thermal to extraction or separation equipment. Methods and apparatus consistent with the present disclosure may extract and concentrate essential elements plant matter. An amount of wasted heat energy collected from a engine that powers an electrical generator may be provided to an evaporation or separation process when electrical power is provided to extraction or separation processing equipment. Computers or electronics that control equipment consistent with the present disclosure may be remotely controlled via a mobile electronic device, when desired. Such computers or electronics may receive sensor data related to the operation of plat matter extractors, related separation equipment, or other equipment may be used to manage a production line. As such, methods and apparatus consistent with the present disclosure may extract essential elements from cannabis plant matter and process those essential elements into cannabis extracts or isolates.

In a system and process for selectively purifying various pharmacologically-relevant components of a source plant such as cannabis, an initial step provides a low-temperature, robust essential oil/terpene capture that also dehydrates and decarboxylates the starting product—fresh raw cannabis—by means of a vacuum-assisted microwave distillation process. By doing the terpene capture under vacuum distillation temperature may be kept low. The low distillation temperature maximizes yields of thermally-sensitive components such as terpenes and cannabinoids. The system includes an oil/water separator configured to prevent leakage of ambient air into the system.

A cavitation mixing apparatus is provided for performing separations from solid material using subcritical liquid CO.sub.2. A cavitation inducing device inside a cavitation mixing vessel is held in place with a cavitation mixer mount comprising at least one fluid channel for equalizing gaseous pressure of CO.sub.2 around the cavitation inducing device. Also described is method of separating oils from a crude plant oil mixture by injecting crude plant oil into a pressurized mixing vessel comprising liquid carbon dioxide and mixing the crude oil with the liquid carbon dioxide under pressure using powered induced cavitation, the cavitation mixing vessel comprising an encapsulated cavitation inducing device.

Methods of decontaminating bone tissue and an apparatus or system for the same are provided. The methods can be multi-batch processes and include contacting the bone tissue having contaminants with carbon dioxide to decontaminate the bone tissue and to form carbon dioxide having contaminants. The contaminated carbon dioxide is collected and the contaminants are removed to obtain purified carbon dioxide which can be recycled to treat contaminated bone tissue. The contaminated carbon dioxide can be purified by bubbling it through water and/or an organic solvent followed by acid treatment, filtering and liquefying the carbon dioxide. Contaminants that can be removed from contaminated bone tissue, and in turn, from contaminated carbon dioxide include infectious organisms, bacteria, viruses, protozoa, parasites, fungi and mold or a mixture thereof
