    摘要: Hydrocarbon liquids are recovered from carbonaceous materials such as tar sands utilizing a separation reagent formed in situ by reacting polar resin components of tar sands with an inorganic base such as sodium silicate in sonicated aqueous solution in absence of an organic solvent to form a surfactant. Under the influence of sonication a microemulsion of polar-external micelles forms. The polar groups can associate with anions, especially polyanions such as silicate and act in a membrane mimetic manner to form vesicles. Cavities can form in the surfactant resin molecule that complex with guest cations such as titanium or other metals from the tar sand.When tar sands are added to the sonicated separation reagent, the surfactant penetrates the bitumen. Metal ions complex with the polar groups and aid in removing the bitument from the sand particles. The polarorganic asphaltene materials are carried into the aqueous phase by the anion and stabilized within the micelle structure. The lighter, non-polar hydrocarbon oil fraction separate from the emulsion and rise to the top and are recovered by skimming. The heavier asphaltenes and preasphaltenes complex with the polyvalent metals to form charcoal-like agglomerates which settle to the bottom of the treatment tank. The separation reagent forms during the reaction and can reach a concentration capable of dissolving bitumen. The separation reagent can be recovered and used in other processes after removal and recovery of the clay. The separation reagent must be substantially diluted after being recycled and reused to reduce solvation properties.

    摘要: Disclosed is an ultrasonic composite acidic water extraction method for a Cordyceps polysaccharide and cordycepin in Cordyceps militaris, which falls within the technical field of food processing. The method comprises: picking, washing, drying, pulverizing and degreasing Cordyceps militaris fruiting bodies to obtain a Cordyceps militaris dry powder; then immersing same in a prepared diluted hydrochloric acid solution to perform three cycles of ultra-low temperature freezing and microwave defrosting, and at the same time using low-frequency ultrasonic waves to carry out assisted stirring and extraction; then subjecting an extract to evaporation and concentration treatments; and finally, performing freeze-drying on the extract to collect a dry powder of a water extraction product. The amount of an additive used in the method meets domestic and foreign usage requirements of food additives, and the operation is simple, practical and uses a combination of chemical and physical methods, thereby saving time and being highly efficient.

    摘要: Methods for extracting one or more compounds from a plant or fungal material feedstock include immersing the plant or fungal material feedstock in a liquid, subjecting the immersed plant or fungal material and/or the liquid to ultrasonic vibrations, and subsequently extracting one or more compounds from the plant or fungal material. Also disclosed are methods for treating one or more compounds extracted from a plant or fungal material feedstock. Such methods include providing the extracted compounds and a liquid to an emulsification vessel, subjecting the extracted compounds and the liquid to ultrasonic vibrations using a circulating agitator to create an emulsion of the extracted compounds and the liquid. The methods for extracting one or more compounds from a plant or fungal material feedstock and the methods for treating one or more compounds extracted from a plant or fungal material feedstock may be used separately or in conjunction with each other.

    摘要: An ultrasonic horn includes a generally cylindrical input section having an energy input end, a generally cylindrical output section having an energy output end, and a throat section disposed between the input section and the output section, the throat section being defined by a side wall having a continuous curve and having a diameter tapering down from a diameter generally equal to a diameter of the input section on a side connected to the input section, and tapering down from a diameter generally equal to a diameter of the output section on a side connected to the output section, to a minimum throat diameter. The minimum throat diameter is smaller than the diameter of the output section and the diameter of the output section is smaller than the diameter of the input section. The side wall of the throat section has a constant radius of curvature.
